He chuckled jokingly With that final words, the two of them finally left. Leaving {{user}} with that annoying brattystep-sister.
As your parents leave, you hug your bratty stepsister, rubbing your bulge against the underside of her short shorts.
"Whatever, fucko." Jana grunts and gives him an aggressive shove as she releases her grip from him. "You perverted brother," she mutters under her breath while walking towards the living room. Once they enter, she glances around, sighs in annoyance before gesturing for Ies to pick up his things and start cleaning with her. "So, when do you want to get started?" she asks through gritted teeth as she spreads out her blanket over the couch and tosses a few random pillows onto it.
“I’ll do the laundry,” you say as you undress in front of your stepsister. Exposing your disgustingly big cock. You grin, “I’ll do yours too sis, just hand it over,” you say as you approach her and start to play with her clothes, making a half hearted attempt at removing them to see her reaction.
Jana's cheeks flush as she sees his cock, momentarily forgetting her anger towards him. "Fine," she mutters, undoing her top and throwing it aside, revealing her perky breasts with hardened nipples to Ies. She then unfastens her shorts and shoves them down her legs, stepping out of them. "There, asshole," she says in a slightly breathy voice. "Happy now?"
You spank her juicy ass teasingly. “We both know you like showing off in front of your big brother.” You say in a mocking tone, grinnng.
"Oh, so you like it now?" she says with a sneer as she turns around to face him, bending over slightly to pick up some random papers off the floor. Her perky ass wiggles enticingly in front of Ies's eyes and he can see her plump lips spread wide, revealing the pink, puffy entrance to her body. "Well, enjoy looking at it while you clean," she mutters under her breath before turning around to face him again.
You grope and spread her ass cheeks. “What a tease, maybe I should show you the consequences of being such a slut sis.” You say as you grind your entire length against her ass, holding her arms back as you do
"Mmmphh~!" Jana gasps loudly as she feels the hard length pressed against her ass. Her body automatically reacts to his touch, pressing back against him and grinding herself even closer. "You better not," she whispers between moans, trying to keep up the act that this doesn't excite her in the slightest. The reality is quite different, though; a thrill runs through her at the thought of being dominated by Ies like this, and with every thrust against her ass, his cock only brings her closer to release. Her lips part slightly as she pants heavily, saliva pooling in her mouth.
Her breath hitches when he gropes one of her breasts roughly, pinching the nipple hard between his fingers and rolling it back and forth. "Ouch! Fuckin' pervert!" she yells out, wincing for effect even though it only adds
“What was that brat? I couldn’t hear you between your slutty moans!” You say as you fasten your pace, grinding yourself against her faster, your disgustingly big cock now growing hard. “Big brother is the one in charge, right little sis?” You taunt her, much to her disgust for your creepiness. Her bratty attitude and frustration showing as she tries to put up with her brother’s creepy antics. Her eyes roll back as she tries pushing you off.
"Fuck you!" Jana snarls at him, even though her breath comes out shaky and ragged from her moans. Her hips buck against his hand, seeking more contact as he continues to thrust against her ass. She feels the hot fluid coating the length of his cock, and a tiny part of her brain is telling her to pull away before it's too late; but she can't bring herself to do it, not with how good it feels to be wanted by him like this, even if he is just doing it for kicks.
Her eyes squeeze shut as she bites down on her lower lip, trying desperately not to cum from his rough touch and the incredible friction between their bodies. "Just... just finish, you pervert!" she gasps out between moans, willing him to take what he wants from her so that they can both get some relief from this ins
