YOU RAN QUICKLY TO your room, attempting to shut the door in sapnap's face but failed and he grabbed your hips and threw you on your bed, "you can run, but you can't hide" he chuckled tickling your sides, as you thrashed against your sheets. all this started solely because you stole his fries from the take-out dinner you had last night.
your legs wrapped around his hips, pulling him closer to your body, his chest was pressed against yours, unintentionally squishing your boobs, he glanced down his eyes catching your cleavage that was exposed by the white cropped tank top. you obviously weren't wearing a bra underneath due to your nipples poking through the fabric.
he knew he wasn't supposed to look at you like this, you were his "little sister", but the forbidden fruits are always sweeter, right? the both of you exchanged ragged breaths, your chest rose to press your chest impossibly closer to his toned one. he laughed again, not because it was funny, but because he was nervous.
one of the hands he had against your hip came up and cupped your cheek, "what would you do if i kissed you?" what kind of question was that? he internally scolded himself for it. "i'd kiss you back of course." your reply was forward, and he wasn't prepared for it. instead of thinking of a way to one-up what you said, he kissed you, you both most likely would regret it in the end, but right now you wanted to indulge in whatever you planned on doing until your mom and his dad got home from their anniversary trip.
you threaded your fingers through his hair, pulling his mouth closer to yours, his tongue played with your bottom lip trying to get you to open your mouth and let his in. when you did, sapnap's tongue ran against the roof of your mouth. "we shouldn't-" you started against his lips, but cut yourself off quickly when his hand trailed down to your boobs.
he pulled away, "we can stop if you want, i'm sorry if i made you uncomfortable" he clarified respectfully, he didn't want you to be uncomfortable with him in any way after whatever you do or don't do tonight happens. you shook your head mumbling something along the lines of how you were fine and you wanted to continue.
sapnap nodded with a cheesy smile, "you're not a virgin or anything-" he started but, you cut him off, "no, i'm not." it was short and sweet, your first time wasn't the best experience, the guy couldn't even make you come. he nodded at your rushed words decided not to push you into an explanation, reaching to tug off the short shorts you were wearing.
he tugged them down just past your thighs, his fingers pushed against your slit through your panties, a high-pitched moan ripped to your reactions to the way he touched you. that dumb cocky smile was still on his face, and how he had you quivering from barely touching you was boosting his already humongous ego. his fingers wrapped around your panties, and he looked up at you asking for permission to remove them, when you nodded he tossed them somewhere on your bedroom floor.
he lifted himself away from you, he pulled his hoodie and t-shirt over his head, and you took a moment to admire him, "you're hot" slipped from your lips and you clapped a hand over your mouth, as they say, honesty is the best policy. sapnap looked down at you, he let out a breathy laugh at how straightforward you were, you wouldn't even talk to him and if you did you were telling him and his friends to shut the hell up from your room.
his fingers slipped into you, circling your clit with his rough thumb, he pumped them into you quickly. he enjoyed watching you thrash, you attempted to lift your hips into his hands, but he was quick to push them back down that damn smirk was back again. "you're my needy whore" he was thoroughly enjoying every minute of this, you never expecting having your mom's boyfriend's son having you at his mercy while they weren't home, you had no issue with it, you just never thought it would happen.
"i want you to say it, say you're my needy whore" he repeated locking eyes with you, and it felt like your stomach was doing somersaults. when you said what he asked it was barely a whisper, his hand gripped your chin, forcing eye contact, "louder" and his fingers' speed increased, as he pinched your puffy clit.
"i'm your needy whore" it was louder this time, and he smirked mumbling about how much of a good girl you were. his fingers' pace sped up unexpectedly and your eyes rolled into the back of your head. you reached down between your bodies, grabbing his wrist as he continued to pump his hand at ungodly speeds.
there was no warning when your orgasm approached, aside from your pussy clamping for on his fingers, and your moans became louder, sounding almost like a pornstar. he fucked you with his fingers through it, mumbling words of praise. your arousal coated his hand, heavy breaths raked through you, "you did so well for me" sapnap praised pressing a kiss to your lips.
you wanted nothing more than to get on your knees for him at that very moment, but there was a distant click, which sounds like the front door's lock turning, footsteps, your name, and a knock on your bedroom door. curses flew from your and sapnap's mouth, "honey, we're home early!" she started excitement laced in her always sugary sweet tone, "oh, is sap in there with you?" your mom questioned her voice was slightly muffled due to being outside the door, she tried to open the door, but then sapnap cringed remembering how he locked it.
you locked eyes with sapnap, aggressively making aimless hand motions, trying to get him to reply to your mother for you, "uh- yeah! we're both in here" he stumbled over his words at first before thinking of something to say, "why's the door locked" she asked still trying to open the door and get to you two, sapnap got up from where he was sitting, he had no idea how to answer her question so he chose not to even reply.
he turned the lock and opened the door for her to walk into the room, when she walked into the room you were underneath the covers of your bed with your laptop in your lap, you were thanking god netflix chose to load fast today and clicked on a random show in the recommended, pausing it as you didn't want to miss the part you were "watching".
your mom looked at you waiting for you to get up and hug her, but you pointed at your stomach, silently telling her you had a stomach ache or something, "are you alright?" the only damn things she's done was question you since she walked to the door, "just um- cramps, sap and i were just watching a movie" you nodded pointing at the screen, that displayed american horror story.
"better go start unpacking" she mumbled walking toward the door, once she was gone it felt like a weight was being lifted off your shoulders, meanwhile sapnap was thinking about how he was going to text dream, quackity, george, and karl about how he was almost caught fingering his step-sister.
