My senior's girlfriend is the envy of everyone. She's very beautiful, with fair skin, big tits, and a huge ass. To be honest, she's just too sexy. She's someone who catches my eye and makes my crotch throb just by being next to me, so she snuck in when my senior wasn't looking during a drinking party and tried to seduce me... And so, for the three days that my senior was away on a business trip, I held her in my arms countless times, cuckolded her, and creampied her. Until he came home, I gave in to my carnal desires and immediately fucked her and creampied her. My sexy-looking girlfriend was even more lewd than I'd imagined.
