Stepping Into It Ch 4

This is a work of fiction, inspired by an adult comic I recently came across. All participating characters are over 18, and any descriptions matching real persons are coincidental. It contains gay male, lesbian sex, incest, as well as group sex, exhibitionist/voyeur, and some erotic couplings. If you are bothered by any of these themes, look elsewhere for your porn.

Otherwise, enjoy...

Lilly ran to her room and barricaded the door, ensuring no one could open it. She was in tears as she sealed herself in, having realized her mistake at being naked in front of her stepbrother and now-ex-girlfriend. What a shitty day this turned out to be!

She'd agreed to stop calling Jack a pervert only to go right back to calling him one for stealing her girlfriend, and she responded to it by streaking downstairs, forgetting to put her clothes on in her rage. Her tears turned to sobs, which then turned to heaving sighs. After a long silence, she resolved herself and got up, grabbed a spare set of clothes, and went to work clearing her barricade.

If Jack could be naked in the house, so could she. If Jeff and her mother could fuck in the living room, so should she! If everyone wanted to be sex-fueled deviants and fuck whomever they wanted, so WOULD she! As soon as she was done, she wrapped herself in a robe and opened the door to find Jack standing there, his hands behind his back and his face subdued.

"Hey, look, I'm really sorry you said that. That, I just wanted to..." Jack started, but before he said another word, Lilly dropped her robe.

"I'm done." She said, "Here, have your fill."

Jack gulped, "What?"

Lilly shook her hips, which made her breasts jiggle, "Have your fill. I'm done with my clothes, I'm done with your perverted staring, and I'm done caring about everything else. You want to fuck Sara? Go ahead, she's all yours, and maybe mine if the mood arises. Just stop bothering me, and I'll stop bothering you." She said.

Jack scratched his head, "And you're choosing to say this, in the nude, why?"

"Because I'm also done with my clothes." Lilly said, "From now on, I'm a nudist at home; that way, no one can say I'm a prude, and I won't care if you stare at me."

Jack sighed and looked away, "Whatever." He grumbled and walked away. Lilly watched him leave, and her mind started racing.

"Aren't you going to stare at me?" She demanded.

"Nope!" Jack said, "Not interested."

"What?! Jack!"

"Leave me alone!" Jack yelled as he descended the stairs. I'm not interested in entrapment today!"

Frustrated, Lilly followed him only to stop dead at the base of the stairs. Sara, who'd come in with Jack, was standing in the living room, as naked as she was. Jack, having ignored Lilly's nudity, embraced Sara and started taking his shirt and pants off. Lilly watched as Jack quickly shed his clothes and sat down, his gaze on the TV and nowhere near her. Her eyes had lingered on Jack's until a shift in the air made her eyes linger downward and she saw his erect cock between his legs. A hand was gently caressing it, Sara's, and she gazed up at Sara's eyes, which were fixed on hers.

Sara watched Lilly watching Jack for any signs of noticing her, but Jack appeared fixated on the hockey game on screen. It was almost as if he didn't want to spy on Lilly, as he had previously been. She took some initiative and leaned into Jack's side, rubbing her body against his. He didn't object and even moved his arm around her shoulders, pulling her in. She responded in kind by grasping his cock and rubbing it slowly in her hand, bringing it to full erection, her eyes never leaving Lilly's gaze.

Lilly's eyes widened in turn, seeing the erect nine-inch beast come to life. She suddenly felt her mouth begin to water and her pussy began to secrete moisture of its own. She shook her head and went to sit down, only to be surprised that her body moved, seemingly on its own accord, and she found herself sitting on the couch, opposite Jack.

Jack continued to ignore her, his attention on the game while his left hand rubbed circles on Sara's back, who encircled his cock in her hand in response. He leaned in and whispered, "Straddle me," to her, grinning. Sara smirked as she nodded and moved, taking his cock in both of her hands as she mounted his lap and sank his cock inside her.

Lilly watched as Sara started bouncing up and down on Jack's cock as Jack placed his hands on her asscheeks, squeezing and infrequently spanking her. After a few minutes, he started grinding upwards, formed a rhythm, and started to fuck in earnest, and soon Sara began to moan and grunt with each of Jack's thrusts. Jack, meanwhile, had taken on hand off her ass and moved to her breasts, taking one of her tits in his hand and brought it to his mouth. He sank his teeth around the nub and nibbled, before taking the whole mound in his mouth and suckling like he was looking for milk.

Lilly's eyes flared as she watched and she cursed herself that her pussy burned for that same kind of affection and lust. She squirmed in her seat and tried in vain to adjust herself for comfort. She couldn't take her eyes off the sight, no matter what she tried.

A moment later, Jack pushed himself off the couch, pulling Sara with him as he flipped around and planted Sara on her back, astride the couch, so that her head was between Lilly's crossed legs and started pounding her with a great deal of force. Sara grunted as her head was pushed into Lilly's legs, and Lilly squirmed to move out of the way, only to remember that she was right up against the armrest. Lilly then realized that Jack had somehow managed to entrap her while avoiding being trapped by her. He had somehow maneuvered her between the proverbial rock and hard place, unable to escape.

Anger filled her eyes, and her lust died away. "You sound like a wounded animal." She said, annoyed, "If this is the best you got, I do not doubt that Sara will leave you in no time!"

"Fuck off." Jack grunted, "I'm driving her nuts!"

"He is, Lil, he really is!" Sara gasped, smirking up at Lilly, "You should try his cock out!"

Lilly scoffed, "Not on your life, Sara. The day I let him touch me will be a cold day in Hell!"

"Good because I'd rather drink water directly from a swamp than touch you." Jack retorted, "Now shut up and let me concentrate!"

"Oh, am I distracting you?" Lilly asked, "Are my tits swaying too fast for you to move in and out of MY girlfriend?"

"So she's YOUR girlfriend again?" Jack asked, "Last time I checked, you gave her leave to fuck me and anyone else a little while ago."

"He's right, Lil, you told us when you stormed outside in nothing but your skin!" Sara added, her grin widening, "Oh, right there, Jack!"

Lilly shook her head, "I was pissed that you had your arms around her! It's not like she's actually having fun with your puny cock inside her."

"You know what? If you think I'm so puny, why don't you risk it and see how cold Hell actually is?" Jack asked, taking his free hand and slapping Sara's breasts as he spoke, which made her yelp.

Lilly's eyes narrowed, "Don't think I won't?"

"I think you won't, because once you do, those 'pervert' lines will reverberate back onto you!" Jack said, "You'll regret ever harassing me because you'll realize I have the best cock you've ever had and you'll want more, but you'll probably never get any more if you keep calling me names and making me feel like the outsider!"

Lilly shook her head, "Finish up in her and let's find out!"

"No, do it now!" Sara gasped, "I'm about to cum!"

Jack smirked and sped up. A minute later, Sara let out an ear-piercing screech as her pussy exploded. Jack smirked and pulled out, pulling Sara upward into a deep kiss. He kept his eyes open and glared at Lilly as Sara adjusted herself into a sitting position, then licked at her lips for a moment before he broke the kiss and stood up, his cock standing straight up before him.

"Is it a cold day in Hell?" He asked.

Lilly's eyes hardened as she jumped a little down on the couch and turned over, her ass sticking in the air, "Fuck me, pervert!"

Jack and Sara grinned as Jack lined up his cock at her snatch and shoved all the way in. Lilly let out a loud scream of surprise as she felt all nine inches of his cock bury into her and felt Jack's hands clamp down on her ass. Without warning, Jack started thrusting in and out of her, not giving her a chance to adjust.

"Jack! Wait! I'm not used to having so much cock inside....AHHH!" Lilly tried but failed as she felt herself surrender to his mighty beast within moments of him entering. Jack smiled as he knew he'd won her over without ever trying.

"You like it, don't you?" He asked.

"Fuck you!" Lilly gasped, shaking her head.

"No, I'm fucking YOU!" Jack retorted, "Now, say you're enjoying it and I'll let you have an orgasm!"

"And if I don't, what then?" Lilly asked, looking over her shoulder.

"Then I'll pull out and shove this cock up your ass!" Jack said, spanking her ass cheeks with both hands.

"Ahh! No! Don't!" Lilly demanded, "I've never had anything in there!"

"Then say it!" Jack said, embedding his cock balls-deep inside her, "Say it, or feel my cock leave your pussy and play with your anus."

Lilly shook her head, and regretted it as soon as she felt him pull out.

"WAIT!" She practically yelled as she felt him pull almost all the way out. He paused and leaned down so his mouth was an inch away from her earlobe.

"Yes, stepsister?" He whispered.

"I like your co,k inside me," Lilly whispered.

"Say it again?" Jack said, putting an inch back inside her.

"I like your cock inside me," Lilly said, a little louder.

"One, more, time!" Jack added, shoving almost all of his cock back inside her.

"I LOVE YOUR COCK INSIDE ME, NOW FUCK ME TIL I CUM!!!!!!!!" Lilly screamed at the top of her lungs.

Jack smirked as he did as she demanded, thrusting into her. He fucked her with abandon for twenty minutes, and made her cum twice, both times making her squirt clear liquid all over the floor and counch cushions. As he fucked her as hard as he could, he felt himself nearing his own end and began to speed up.

"I'm about to cum," he breathed, "Are you on the pill?"

Lilly's eyes widened, "No! I went off it when I dumped Eric!" She said, breathlessly.

"Okay, then!" Jack said as he pulled out and flipped Lilly around. He lined his cock up with her face and began jerking off. Within seconds, a torrent of three blasts erupted from his cock and splattered her lips, cheeks, and forehead, coating her with his cum.

Lilly opened her mouth in shock, which was a mistake as the last little globs of his cum entered her mouth and she tasted his seed, which made her eyes widen in realization. When Jack pulled away, Sara jumped in and began licking up the cum from Lilly's face. Lilly kept her mouth and eyes shut as Sara lapped up all of the cum until her face was nearly cum-free. When she opened her eyes, Sara moved in and kissed Lilly on the lips, and they shared the taste of Jack's cum together.

After a moment of them locking tongues, they broke apart, and Lilly lay back on the couch.

Jack leaned in, "I was good, wasn't I?"

Lilly looked up at him and snarled, "Yes, but don't ever think this gives you permission to fuck me again!"

Jack grinned, "Good, because I've gotten my fill of you!" He said, standing tall, his cock deflating, but still semi-erect, "I've got a bigger prize in mind."

Lilly glared at him as a crazy thought crossed her mind, "You don't mean..."

But before she could put the thought into words, the lights of a car reached the driveway outside, and Lilly glanced over to see her mother and stepdad opening their doors. She immediately got up and ran out of the room, up the stairs and into her bedroom. Jack and Sara, likewise, grabbed their clothes and ran up the stairs as well. Two doors slammed shut seconds before the front door opened.

Laura and Jeff grinned as they walked into the quiet house. 'The kids must be studying,' Laura thought as she closed the door behind them and took her shoes off. They walked into the living room and noticed that the TV was on, but no one was watching it. Jeff sighed as he moved to shut it off when he noticed a small pair of panties lying on the floor near the couch. He gestured for Laura to join him as he picked up the panties and showed her.

"Huh, looks like someone got lucky a moment ago!" She said.

"But who, and where, are they now?" Jeff asked.

Laura stepped up and took the panties from her husband, examining them. "These aren't Lilly's, so they must be Sara's, " she said when she noticed a glob of something on the floor. She poked Jeff and pointed.

Jeff took a tissue and wiped up the glob, and examined it, "Fresh sperm." He said aloud, "Either they had a boy over and were having a threesome, or Jack has gotten lucky, either with Sara or a girl who has Sara's taste in panties."

"And if either scenario is the case, where are they now?" Laura added, "Let's put our groceries away and check on the kids, shall we?"

And they did exactly that, taking the panties into the kitchen where Jeff placed them on the table while Laura put takeout and put it on the counter before dropping the sodas and wine in the fridge to cool. When she was done, she ascended the stairs and knocked on Lilly's door.

"I'm busy!" Came Lilly's voice.

"When you're decent, come down to dinner!" Laura said, stepping away and moving to Jack's door.

"I'm studying!" Jack yelled as soon as she knocked.

"If you're studying human anatomy, it's a little late to change careers." Laura said, "If you have a study buddy, be sure to let them know their panties are on the kitchen table!"

"God damnit!" Came Sara's muffled voice.

Laura grinned, "Sara, I'm not going to pretend that I know what's going on, but you two better be dressed in five minutes or your food's going in the trash!"

With that, she walked back to the kitchen. Three minutes later, Lilly, Sara, and Jack arrived in the kitchen where Jeff and Laura were seated at the table. Sara went and grabbed her panties without a word and stood off to the side as Jack and Lilly sat down, grabbed a plate full of food and started to eat, only for Jeff to clear his throat, and they put their forks down.

"I'm not going to pretend like I know what you were doing upstairs," Jeff said, "But can either of you explain how Sara's panties ended up on the floor near a glob of semen?"

Jack quickly cleared his throat, "Sara wanted to experiment, and I was a willing participant. Lilly caught us, and we scrambled to get dressed, and I guess she just forgot to put those on. You guys were coming in, and we didn't want to get caught a second time, so we ran."

Jeff nodded and turned to Lilly, "Is this true?"

Lilly looked from Jack to Jeff before she said, "Yes, it's true."

Jeff looked at Laura, who shrugged, "Okay, tuck in." He said. They ate their dinner in silence, after which Sara was sent home and Lilly and Jack returned to their respective rooms. Jeff and Laura went and did a deep cleaning of the living room.

***

While Jeff and Laura cleaned the living room, Lilly went to Jack's room and knocked.

"Who is it?" Jack called.

"It's me, can I come in?" Lilly said.

"You may," Jack said.

Lilly opened the door and slipped in, closing it behind her. Jack was sitting on his bed, his shirt off and a pair of pyjama pants on. A book was in his hand, which he bookmarked and set aside.

"What's up?" He asked.

Lilly shifted nervously, "Thank you for not telling the complete truth." She said, "I know that it would have raised a lot of questions."

"Forget about it." Jack said, "And remember that what happened today isn't going to continue."

Lilly blinked, "Why not?" She asked, surprising herself with her words, "I mean, yes, I know we can't have sex again, but...what the fuck was that today?"

"What was what?" Jack asked.

"You decline my declaration that you can see me nude, you ignore me and fuck MY girlfriend in front of me, then somehow convince me to let you inside me. How did you do that, anyway?" Lilly said.

"I did nothing." Jack said, "You did that on your own."

"You must have done something!" Lilly demanded, "Drugs, hypnosis, something!"

"I'm not the one who exposed themselves in front of their stepsibling." Jack said, "I'm not the one who followed them into the living room, watched them fuck Sara, or prostrate themself on the couch for a good fucking. You did that of your own accord. I can't explain it any more than you can, but maybe you can."

"How?" Lilly asked.

"By answering a few key questions." Jack said, "Do you find me attractive?"

Lilly blinked and looked uncomfortable. "Does it matter?"

"Yes." Jack said, "Am I attractive to you?"

Lilly sighed, "You are."

Jack smiled, "Good. Next question, do I have a nice cock?"

Lilly sighed again. "Yes. Where is this going?"

Jack waved it off, "Somewhere. Last question: Do you want to fuck my dad?"

"Go fuck yourself!" Lilly said, turning to the door.

"Stop right there!" Jack said, standing up. Lilly stopped, and looked embarrassed that she did, "You want to know why you did what you did? I'll tell you: It's because you want to stop being a prude. You see me embracing nudity at home, enjoying the fruits of a good sex life, and you want to free yourself from the shackles of the past, where your ex fucked your father and you couldn't handle it.

"You want to be free of the guilt that you didn't see it coming, and you want the freedom to experience something like it yourself. So, I ask again. Do. You. Want. To. Fuck. My. Father? Yes or No?"

Lilly sighed and turned back around, "Yes."

Jack smiled, "Good. Take your clothes off."

Lilly shook her head, "You're a freak."

"And you're a pervert." Jack retorted, "Now, fucking strip and let's have some fun!"

Lilly reluctantly obeyed, pulling her shirt and pants off, dropping her panties, and pulling her socks off within seconds of being ordered. Jack smirked as he watched her and when she was completely nude, pushed his pyjama pants down, revealing his erect cock. He approached and reached out for Lilly, who backed up to the closed door, but he reached her before she could grasp the handle.

Jack took hold of her breast in one hand and grabbed her crotch with the other. He sank three fingers into her pussy with ease as he twerked her nipple with his other forefinger and thumb. Lilly let out a pained moan, fighting the urge to shout. Jack then closed the gap and sank his lips on her unattended tit, which made Lilly gasp in ecstasy as he ran his tongue over her nipple and mound. He grinned into her breast as he worked her body over.

Each movement made her squirm. All three at the same time made her cum in seconds. He felt her pussy moisten with cum as he pulled his fingers out and released her nipples, standing inches away as he brought his hand to her mouth.

"Taste yourself." He said.

Lilly obeyed, opening her mouth and took his fingers inside, her tongue lapping up her pussy juices. He smiled as he shoved his cock inside her without warning, and pushed his fingers deeper inside her mouth to prevent her from objecting. Without ceremony, he fucked her fast and hard. After a few minutes, he pulled his hand from her mouth and with both his free hands, lifted her off the ground by her hips and pulled them around to clamp on his ass. She instinctively wrapped her arms around him as he held her in place against the door and they kept on fucking.

After a while, Jack felt a need to cum and sped up, ensuring that Lilly came on his cock before he put her legs down and let her sink to the ground before he repeated what he'd done earlier and came all over her mouth and cheeks. This time, however, he pulled her to her feet after he was done and licked up his own cum instead. Lilly's eyes widened as she felt his tongue on her face and was shocked when he opened his mouth and kissed her, sharing his cum with her.
