Yumi Yagi, the most voluptuous athlete in S1, reaches orgasm, convulses, and arches her back repeatedly with her own cowgirl position! Straddling a man, she slams or rubs her thick, massive ass. This cowgirl position is a must-see! The up-and-down motion makes loud 'slapping' sounds while moving vigorously; the front-to-back motion has smooth hip movements that stir inside the vagina. Can you hold back from coming with her relentless, full-force cowgirl position that she can't stop because it feels too good?
