彼女が不在の２日間、海外帰りの彼女の姉のえぐい腰使い誘惑されて何度も何度も射精を繰り返した…。

"Hey... which do you like better, my sister or me?" Her older sister suddenly appeared and was extremely erotic. Her breasts are much bigger than hers, and she uses her hips more aggressively and in a variety of ways. After two whole days of being straddled, rubbed, and squeezed by my cock, I ejaculated a lifetime's worth of semen into my girlfriend's sister... "You can still do it, right? Just one more time..." The worst but best two days, writhing in agony with guilt and unknown pleasure. Unrestrained, forceful, and with the best physical beauty. A forbidden NTR masterpiece with her sister is born here!
