You’re at your mate’s house waiting for him to get ready for a night out when you’re greeted by his sister who’s also getting ready to go out, but when she introduces herself she’s topless and doesn’t even realize it! So obviously you get your COCK out and start WANKING when she leaves the room! But she finishes getting ready and catches you JERKING it in her living room! But when you tell her it’s over her, she’s flattered and can’t resist teasing you more! LUCKY!
