With no acting or embellishment, Nanatsumori Riri takes on twenty muscular men in a relentless group-sex marathon. Her mouth and pussy stay filled with cocks while more men wait on every side, and the nonstop pounding makes her convulse through unprecedented orgasms. Even when she cries that she cannot take any more, the line keeps moving and the thrusting never stops. Barely able to stand, she is held up for one final forced pounding, then covered in a huge load of semen and left dazed. She later says she could not stand for some time afterward.
