Emily hushed Claire as she giggled. They were currently sneaking into my room. It was late and Mom was already asleep, so we definitely wouldn't want to wake her up to catch us messing around. I was sitting on my bed in just my boxers when they opened the door.
"So, think you'll be ready?" Claire asked. Emily and her had made plans for me. She was in nothing but a t-shirt, her legs crossed, showing off her cute pussy. Emily in nothing but her panties, crawled over closer to us, her tits swinging. My sister and I hardly wore anything in the house now, our time together in the tub had made us very comfortable with each other's bodies.
"Yeah, I- I guess so." I spoke up.
"You want to, don't you? I mean, she is sexy." Claire said. "If I had a dick, I know I'd want to."
"Have you had sex before?" Emily asked quietly. "L-like, will you be losing your virginity to her?"
"Emily! Of course he's had sex before." She rolled her eyes at her question. "Just look at him, and look at this."
Claire pulled back one of my boxer legs, showing off my soft cock. Even when flaccid, it had a decent length, though I was flustered at her showing it off so suddenly. She took my soft shaft in her hand, making it start to grow in her hand.
"You think a cock like this hasn't fucked before?" She wiggled it as if to further her point. "Your girlfriends had to have loved this thing." Claire smiled at me with a soft blush.
"Come on Claire, don't make him talk about this stuff!" Emily said all flustered. "You don't have to tell us anything Jack." Her face was beet red.
"What? Oh come on Em, don't get embarrassed about this stuff. We're gonna have to watch him fuck Mom anyways." She said, a devious grin on her face.
"Y-yeah I guess so..." Emily said, her arms crossed. She was still a bit nervous about sex stuff, it was still pretty new for her.
"I have once." I spoke up. "But it was pretty awkward, to be honest."
"Who was it with? That girl you went to prom with, in high school? It was her, wasn't it?!" Emily said, almost accusatory. Was I imagining things, or was my sister getting jealous?
"Emily, Emily. Don't pull a Mom and get upset Jack's been with someone else. There's enough of him to go around. Once Mom gets a good fucking she'll come to her senses and let us all share his big dick."
Claire spoke with my cock still in her hand, her idle rubbing making me hard, the erection sticking up out from the loose boxer leg.
"God just look at this thing." Claire spoke again, a mischievous glimmer in her eye. "I'd fuck it right now. But the minute it slides into me, I'd moan so loud it would wake up Mom in an instant."
Emily gazed at my boner like it was some forbidden treasure. "Y-you can't do that anyways! Mom said not to, and we can't disobey her rules."
Claire rolled her eyes. "Whatever. You've always been the goody-two-shoes Emily. Gotta live a little, girl."
Claire continued jerking me off, my soft moans escaping my lips. "But- you're right, I don't wanna get on Mom's bad side again. I just got in her good graces after eating her out last week.. For now... Jack, I haven't even gotten a taste of this cock yet."
My dick twitched a bit at Claire's words. She was right, for all the teasing she did around the house, we'd hadn't done anything sexual yet.
Claire, still stroking me, had me at full mast. She looked at me and bit her lip. "You haven't even tried to do anything with me Jack, why's that?" Her other hand went straight for my balls, massaging them. Both her hands were on me now, and god they felt nice.
"Has me waving my ass around not been good enough for you? Only like girls with big tits?" She asked, in a joking sad tone, teasing me. Her face grew closer to mine as she stroked, as if to plant a kiss. "That's so disappointing Jack. Though I bet I can convince you you'll like us small chested girls just as much."
Claire's lips met mine, planting a hot wet kiss. Her lips were so thin, soft. She was a very good kisser, our lips locking immediately. She pushed her tongue in my mouth pushing against mine, and our tongues danced together.
Her hands still stroked me as we kissed, one hand on my bare chest now to support herself, but the other still firmly stroking me. My hips bucked as she continued. For a second, she pulled away her lips and licked the palm of her hand, covering it in her saliva. I saw her eyes as she did it, twinkling with lust.
She went back to kissing me, as she palmed the head of my cock, rubbing my sensitive bellend. She stroked up and down, making me quiver. It was like she found a cheat to make my body lose control.
"Mmph, fuck, Claire!" I breathed out as I broke our kiss. I didn't want it to stop, but I didn't want to cum so soon. Her face was filled with lust, mouth covered in saliva with her mouth hanging open. She licked her lips some more, then dropped her head down.
The next thing I felt was Claire's tongue on my tip, then her lips right around me. My body quivered some more, hips thrusting. I look down to see her beautiful blonde hair bobbing up and down on my cock. Claire was always good with boys, and now I knew why. She was an amazing cocksucker with plenty of experience, I was sure. My mouth gaped open as she easily deepthroated my entire length, her tongue touching the top of my ballsack.
gluck, gluck, sluck, gluck
The sounds coming from her mouth were exciting, and so sexy. My cock was gliding down her throat, then right back up as her head continued to bob on her big brother's cock.
I needed to cum, I was dying for it. Impatient, or maybe just entirely needy, I grabbed the back of her head, and with her mouth stroked my cock to my perfect rhythm. Up and down, up and down. I felt her throat muscles trying to swallow it, and quivered. It was coming.
My hips thrusted one last time as my orgasm shot through my cock to my entire body. Claire's head was secured deeply on my dick as my hips quivered, shooting rope after rope of cum down her throat. Finally she pulled away and caught her breath.
"Oh fuck Jack. Jesus. I'd never taken it- so fucking deep." She sputtered a bit as she spoke and caught her breath. "If that's anything like the pounding you're going to give Mom tomorrow, she's going to get addicted. Holy shit..."
We both looked at Emily after forgetting for a minute she was in the room. She sat there red in the face, fingers rubbing her pussy through soaked panties.
"G-good luck tomorrow, Jack." She smiled.
...
7PM came quickly the next day.
"They left? Where?" Mom asked.
"I don't know, they just left. Maybe to hang out with a friend?"
"With the water shortage still happening? They better not be going to a pool, did you hear about the family who would go just to take a bath, and drink from it? They used it as a bathroom too!" Mom, always up to date on the latest scandals.
"Well, they're going to miss bath time..." She sounded a bit sad, despite the 'drama' lately, family bath time had become a bit of a nice place to relax with everyone all together in one place. Mom had even installed a bigger tub to give more room for everyone. This past week though, she was quieter even when we were all together. "Guess it's just us today."
I followed Mom to the bathroom, where she undressed and tossed her clothes in the bin. I watched her as she exposed her naked curves to me, first by taking off her shirt. Mom wasn't like my sisters, walking around in barely anything, but I had noticed she'd forgone her bra most of the time. I'd see her fabric-stretching tits push her nipples against her shirts every day now.
Mom saw my gawking. "Aren't you used to this by now?" She smirked, teasing me by pinching one of her nipples with her hand and giving her boob giving a jiggle. "You young men are so predictable. But what is a mother to do?" She shrugged. I knew she liked the attention though, she always made sure to put on a little show when she undressed in front of me.
Next, she started to take off her pants, wriggling her jeans off of her fat ass with a little shake, the pants tight on her figure. I watched as they slid off of her, catching a view of her wide backside. I was surprised when I saw her bare ass, no panties covering it up.
"Hmm."
