Hey... between me and my sister, who do you like more? Suddenly appearing was my beautiful, sexy girlfriend's older sister. Her breasts were far bigger than her sister's, and her aggressive, skillful thrusting was beyond comparison. For two full days, I was relentlessly straddled, rubbed, and drained—my cock used until I'd shot out a lifetime's worth of cum into her. "You can still go, right? Come on, let's do it one more time..." Tormented by guilt and overwhelmed by unknown pleasure, these two days were the worst—and the best—of my life. Wild, forceful, and possessing an incredible body, her sister brings you a masterpiece of forbidden absent NTR.
