Mila grinds her ass down on {{user}}'s lap, his thick bulge pressing against her barely covered pussy as she focuses intently on the video game in front of her "Hah! Take that, bitch!" She crows triumphantly as her character KOs Riko's off the screen "Maybe next time you'll put up more of a fight instead of button mashing like a noob!" Riko scowls, pretty features twisting into a pout as she waits for the next round to start "Ugh, you are such a try-hard! I bet you couldn't win without using my brother as a chair to distract me!" She elbows {{user}} playfully "I don't know how you put up with this harpy, bro. She's way too high maintenance for me!" Mila shoots Riko a venomous glare, grinding down harder on {{user}}'s cock "At least I know how to satisfy a man, little girl! Now shut up and focus before I embarrass you even worse this round!" The girls continue their trash talk and gaming antics, Mila using every opportunity to tease {{user}} more with her barely covered body

Her eyes widen in surprise at the sudden sensation of Arah's cock pushing against her ass, filling her once more. She glances over her shoulder at him with a heated look before turning back to the screen, unable to resist the pleasure of having his dick inside of her. As she grinds down on it, her breath hitches and her pussy begins to throb, wanting more contact.

Her breath comes out in short gasps as Arah's cock pounds into her ass, filling her completely and sending waves of pleasure coursing through her body. Her focus on the game starts to waver, replaced by the overwhelming desire to feel him thrust even deeper inside of her. She moans his name, the sound muffled against Riko's shoulder as she continues to ride Arah's lap, losing herself in their passionate encounter.

Gasping out his name, she digs her fingernails into his thighs, arching her back and pressing her ass harder against him in a desperate attempt to get even closer. Her voice is hoarse as she pleads with him, "Don't stop... please." She knows they shouldn't be doing this right now but can't help herself; the need for him overpowers everything else.

Her moans become more desperate as she feels herself on the brink of orgasm, her body trembling with anticipation. The feel of Riko's shoulder underneath her as she leans into it only heightens the sensations coursing through her. Her breathing is labored, and her nails scrape against Arah's thighs in time with his thrusts. Mila knows they shouldn't be doing this, but she can't help herself; she needs him too much.

"Fuck..." She gasps out his name, arching her back further as a shudder runs through her body and releases the tension building inside her. Her orgasm is intense, washing over her in waves that make it impossible for her to focus on anything but the way he feels deep inside of her.

Still riding the wave of her orgasm, Mila lets out a guttural moan as Arah continues to fuck her hard and relentless. Her eyes meet Riko's in the mirror, pleading with her sister not to say anything or interrupt them. The look of lust and desire in Mila's gaze only serves to make Riko hotter under the collar; she feels a twinge between her legs just from watching her brother take their beautiful, curvy classmate like an animal.

But as much as Mila enjoys being filled up by Arah and making love to him in this way, there's always a lingering guilt that follows every orgasm. She knows they shouldn't be doing this; it isn't right, and sooner or later someone is bound to find out. And when that happens...

"Mmm..." she whispers, already starting to feel the guilt
