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 breath catches as his huge length fills her up completely, stretching her tight entrance and forcing a moan out of her throat "Fuck..." She whispers hoarsely, grinding against him roughly now, feeling the head of his cock nudge against something inside her that makes her whole body tremble with desire "Shh..." He murmurs, holding her steady as she continues to ride his cock, clearly in complete control but obviously struggling to keep from cumming on his lap already "Let's finish this round first... then we can see how much more satisfying I am than a stupid video game."

Her hands fly off the controller, reaching back to grip onto his wrists as she tries to steady herself on him with both arms instead "Taran..." She gasps out, her breath quickening even more, trying and failing to concentrate on the game anymore. Her nipples are hard beneath his hands, begging for him to touch them "Fuck... you're so good at that... I can't think..."

"You know I could kick your ass if you weren't such... a distraction," she pants, eyes closed as his hands massage her tender nipples through the thin fabric of her bra. "But maybe that's just what I need to make my comeback. Shutting you out." She shoves him gently with one hand, grinning wickedly as she focuses on their sibling rivalry once more... for now.

"Well, then..." She bites her lower lip and slowly presses herself down harder on his cock, grinding against him with newfound determination "Prove it."

Her body tenses as he touches her just right, the sensation spiraling straight through her core and up to her head in a blinding rush of pleasure that threatens to send her over the edge. She tries to hold out just a little longer, but it's nearly impossible with him grinding against her like this. With one final thrust, she comes hard around his fingers, "Yes!" Her voice cracks as she cums, her tight pussy squeezing and massaging his cock relentlessly

Her body is still shaking with orgasmic aftershocks as he comes inside her, his thick seed filling her up and spreading heat through her entire being. She collapses against him bonelessly, too spent to even muster a taunt or insult right now. Instead, she nestles closer into his chest, nuzzling his neck as their breaths slowly return to normal. "You know I love it when you do that," she whispers. "Well... I just love you." His words send another shiver down her spine and a satisfied smile curves across her lips. For now, the bitchy front is gone, replaced with the loving girlfriend who has always been there for him - flaws and all. They stay like this for a while longer, content in their post-orgasmic cuddle, until Riko finally wins the round and laughs at them both, "Guess you'll have to find someone else to be your little distraction now!"
