going to the beach with stepbro!dennis (or bf!dennis and stepdad!robby? 🫣) and wearing the tiniest bikini you can find, it barely covers anything, one wrong move and your nipple is out, the bottoms is basically a g string.
i feel like with stepbro!dennis he would get really possessive and be groping you all day, maybe even moving your bottoms to the side to snag a peek at your cunt 🤭
with bf!dennis and stepdad!robby i think dennis would try to control himself since he doesnt wanna make a bad impression on your stepfather. but robby is shamelessly ogling you, staring directly at your boobs when talking to you, or asking you to sit on his lap while he's hard as a rock 🤭 bonus points for some tummy mention because my mind is still reeling from that tummy shot in the trailer 😵💫
stepbro!dennis would be all OVER goin to the beach with you. absolutely elated as soon as you bring it up, not just to see you half naked but in general just to have fun. mostly to see you half naked
warnings: fauxcest, stepdad!robby, stepbro!dennis.
so like your family definitely has one of those big ass beach tent things that you can’t see inside of and he’s using that to his advantage. offering to help you moisturize sunscreen into your skin, using it as an excuse to get handsy. once you’re laid out his hands are all over you, back, arms, ass, thighs, legs. resting his knees over the back of your legs so you can’t get up before pulling your bottoms to the side. “den—dennis! what are you doing? mom and dad could be back any second.” comes your panicked whines trying to push the man off you. “m’sorry just..you look so pretty I just wanna see okay?” youre huffing about it but you relent.
he leans down nosing over the back of your neck, inhaling deeply. the smell of salt on your skin and your sweat is enough to have him half hard. his tongue peeking out as he licks down your shoulder. “you’re so gross!” ignoring you he continues moving down your back in wet streaks. lifting your arm and sticking his nose there, where the scent of your sweat is the strongest n licking there too. him panting all the while, you squeal, the sensation a confusing mess of arousing and horribly ticklish. continuing his earlier practice he tugs the bottoms to the side coming up off your back to peer between your legs. the peek he gets sends a shiver though him. bringing his spare hand down to pull apart the glistening mess “wanna taste you..you’re wet.” a finger slides through your sticky mess, ever so slightly pushing against your hole “can’t den, you know that— you said just a look!.”
he’s basically pouting knowing you’re right. but god if this isn’t the hottest thing he’s seen. holding his sister down and touching her to his hearts content. the previous half boner he was sporting now growing into a full hard-on. he likes it, loves it even knowing that he isn’t forcing you but the fact that he could..and you’d like it is enough to have him just as wet as you.
maybe he even slides his cock between the cheek of your ass and the swimsuit, rutting against you until he’s spilling all over your lower back.
now, for stepdad!robby he definitely noticed dennis’ behavior towards you, mostly because he was staring too. with his darling stepdaughter running around in scraps, how could he not look? you’re breathtaking. young and pretty, it makes his cock twitch from where he sits in his folding chair. watching you and dennis splash around, unfortunately for you though all the running around loosens the tie on your top. causing you to rush out of the water and back into the tent and past michael with a yelp. while dennis tries to hide his obvious boner robby is gently asking if you need help. and of course your nodding with a “yes please.” voice shy n low.
ordering you to sit on his lap so he can retie it for you has you happily obliging. plush thighs on top of his firm ones, covered in course hair that makes you squirm. “gotta come closer honey..s’okay.” large hands grip your hips sliding you back on his lap. his soft tummy presses to your back and his hands begin to work at your top. all your squirming making him groan, “stop moving.” “sorry..” the friction making his dick kick to life in his shorts pressing against your cunt. “robby you’re—“ he hums out a low “shh”
“your fault for all that moving baby.” once he’s done you try to get up but his palms keep you still. “give me a sec honey, I need to calm down before you get up.”
imagining both of them perving on you all day is so fun. maybe dennis even intentionally loosens the straps of your bottoms while you both swim. so he has an excuse to go under water and “look” for them. which, there is no looking he grabbed them they second they came off. he just wants to look, n maybe even finger you in the water who knows!!
