The seniors in the club, who are notorious as the "slutty sisters," have targeted me, a guy with a girlfriend!? I made a mistake by showing kindness to my seniors, who got drunk and couldn't go home, by letting them stay in my room. When they get drunk and horny, they sneak around like hyenas, pressing their big tits against her and forcing her to get a hard on, wanting to fuck her. Their battle-hardened combination of nighttime sex makes my useless dick instantly fully erect... and they suck him until he runs out of sperm.
