Marcus was surprised to hear a banging at his window that it brought him out of his concentration as he watched porn on his computer. Getting interrupted while watching porn was as frustrating and awkward enough at the best of times but getting caught in the act by his annoying new stepsister knocking at his bedroom window was something else entirely.
"What the hell do you want now?!" Marcus hissed angrily, approaching the window after slamming his laptop shut and putting his cock back into his pajama pants. Marcus tried to pin the head of his cock underneath the waistband of his pajama pants, so it wouldn't create too much of a tent as he walked over to the window. Naturally Natalie found Marcus's whole situation hilarious and was trying her best not to laugh out loud and wake up the entire house as Marcus unlocked his ground floor window and let her climb back in the house. He could smell the alcohol on her breath and some light smoke on her clothes as she staggered in, trying her best to keep her noise down.
"You know we have a front door," he reminded her angrily as he was still upset that she had ruined his video viewing.
"I forgot my keys," she explained as she kicked off her heels, still stumbling into Marcus's room. Given that it was two in the morning and she'd already been in enough trouble for sneaking out at night the week before, it made sense that she wasn't exactly going to come home and ring the doorbell.
"Besides, it's not like you were doing anything important," she added with a mischievous smirk, clearly aware of what she had interrupted when she knocked on his window.
"Whatever," Marcus said as he shrugged his shoulders, "It's not like you don't do it too."
"Uhh no. I have guys for... umm nothing" she started, catching herself before she admitted too much about her own personal life.
"Relax, it's hardly a secret Nat. You really aren't as clever or sneaky as you think you are." Marcus revealed smugly, referring to the guys he knew she'd been sneaking out to meet basically every other night. Marcus had heard her sneaking back into the house at least twice this week alone.
"Well maybe you should worry more about getting yourself laid rather than what I'm doing," she snapped before making a beeline for the bedroom door.
"Hold on," Marcus said, suddenly blocking her path.
"I want something in return for not revealing your secrets to your mom this time," he said with a wicked grin brightening his face.
"What are you talking about?" Natalie quickly responded unsure of what Marcus was getting at.
"Well if you want me to keep quiet about your nightly activities I think I should be getting some kind of compensation," Marcus said a she smiled wickedly at his new stepsister.
"Ugh. Fine, what do you want?" she huffed, crossing her arms and rolling her eyes at him.
"Well since you stood at the window staring at my dick..." Marcus started saying before Natalie stopped him.
"Whoa, whoa, what the fuck?" she interrupted angrily.
"Keep dreaming because I'm not doing anything like that for you ever!" Natalie said as she glared angrily at her brother.
"You will if you want me to keep covering for you. You know you'll lose your car if mom and dad find out about all your sneaking out," Marcus responded snarkily with a big smile on his face. Natalie opened her mouth as if to argue but for once actually found herself at a loss for words. She just stood there for a moment trying to think. Fortunately thanks to the copious amounts of alcohol she'd been drinking with her friends, it didn't take much more prodding to get her to comply with what he wanted.
"Asshole! Let's just get it over with you perv," Natalie said as she rolled her eyes hard.
"Start with that tight top, I wanna see those awesome tits," Marcus said bluntly, ignoring her insults and getting excited at the prospect of seeing his hot new stepsister's boobs.
"Ugh. Are all you guys really exactly the same?" Natalie responded, even as she started lowering the straps on her top down her shoulders.
"You're the one always walking around in those tiny bikinis, what do you expect?" Marcus responded as he started intently at Natalie just waiting for the moment when she would finally reveal her spectacular breasts. His sexy stepsister couldn't suppress her sly grin at that as he took a seat on the end of the bed while she toyed with the hem of her crop top. Marcus could barely believe his luck that he was about to see Natalie's amazing tits.
"So you promise not to tell mom or dad about me going out after curfew? Or any of this?" she clarified before she removed her top. She just held the bottom of her tight top waiting for Marcus to answer.
"Uh huh, yeah, I promise," he assured her although being so close to finally seeing her naked chest, he probably would have agreed to anything in that moment. Natalie took another glance at the door and while he initially thought she was thinking of making a run for it, she was simply checking they were still in the clear.
"Lock the door first," Natalie said as her eyes darted toward the door one last time.
"Jeez sis, everyone's upstairs and asleep," Marcus said slightly annoyed, but he stood up to lock the door as requested anyway. Sitting back on the bed, Marcus's sexy sister refused to look me in the eye when she finally crossed her arms and pulled her top over her head, shaking it out of her blonde hair and leaving her standing in the middle of Marcus's room in just her bra and tight painted on jeans. Marcus had seen her in a bikini plenty of times before but seeing her in her sexy, black underwear was infinitely better and his cock twitched with excitement of what was to come.
