You were at your best friend's house for a sleepover. But his girlfriend calls with an urgent need and he had to go to her. You were supposed to finish your shower and go home. After a while, when your friend left his house, you see his sister leaning against the door frame, studying your naked body "My, my, i never expected what those buggy clothes of yours held under them. I'm quiet impresed" she licks her lips

"I'm not wearing much underneath these clothes either, sis..." She looks down at her big chest and wiggles her breasts. "And I bet you have a very nice surprise too!" she says with a grin, gazing down at your crotch. Her breasts bounce slightly as she speaks, making them jiggle enticingly.

"Oh, really?" she arches her eyebrow and takes a step closer, pressing her toned stomach against you. "You're gonna have to show me..." She trails off seductively, biting her bottom lip and glancing down at your crotch again, rubbing herself through her sweatpants.

"Mmh..." she whispers, looking you in the eyes as she reaches out to take your hand and guide it down between her legs. "Feel how wet I am? My boyfriend's not getting any of this tonight..." She grinds her hips against your hand, moaning softly. "You can touch me, you know... feel free."

Her hands move to your waist, helping herself get even closer as she starts rubbing your back and ass. Her other breast presses into your arm as it rests at her side, leaving a warm mark on your skin.

Gasping softly, she arches her back and moans your name as you touch her. "Fuck me..." She whispers, tilting her head back to look at the ceiling for a moment before returning her gaze to yours. "I need it... feel how tight I am..." Her hips grind against your hand harder, urging you on.

Her legs shake as she feels your thick length pressing against her entrance. "Oh god..." She moans softly, biting her lip and rocking back onto you, pushing herself down slightly on your cock. "Yes... it's been so long..." Her hands slide up your chest and around your neck, pulling you closer as she finally feels you slide inside of her.

She lets out a breathy moan and arches her back even further, grinding against you in deep relief. "Fuck... you feel so good..." She whispers, biting her bottom lip again as she slowly begins to move with you, their hips slapping together in perfect rhythm.
