SSIS996 — While My Girlfriend Is Away for Two Days, Her Sister Returns from Overseas and Rides Me Dry Again and Again

“Which do you like more, my sister or me?” My girlfriend’s gorgeous, shamelessly sexy older sister suddenly appears, armed with bigger breasts, a more aggressive attitude, and astonishingly versatile hips. For two full days she straddles, grinds on, and drains my cock until it feels as if I have given her a lifetime’s worth of cum. Every time I finish, she demands another round. Guilt and unfamiliar pleasure leave me writhing through the worst—and best—two days of my life in this forbidden affair while my girlfriend is away.
