SDMU-682 Couple swap 'continuous vaginal internal ejaculation' battle! Wife... another man's husband 'come quickly' cowgirl style makes him ejaculate inside, 100,000 yen per shot! Husband... aiming for the prize money 'no way I'm ejaculating inside' holds

A newlywed couple challenges a game where 'they exchange partners, the wife rides on top of the opponent's partner for raw vaginal penetration and ejaculation inside, with the prize money increasing each time'! The more internal ejaculations they achieve in 90 minutes using only the cowgirl position, the higher the prize money goes infinitely! It's embarrassing to have sex with another man right next to her beloved husband, but the raw sex feels so good that she can't stop moving her hips!!
