DVAJ-459 Trapped in a room where you can't leave until you've cum 20 times... Even after having sex with my wife repeatedly, I didn't have enough sperm, so I ended up lending my wife's body to the super-stud old man trapped with us. Kawakami Nanami

When I woke up, my wife and I were locked in a sealed room with some stranger. The voice of the perpetrator said that if we could collect 70ml of semen within 24 hours, we would be released; otherwise, something terrible awaits us. Helplessly, we had sex repeatedly, but it was nowhere near 70ml, and eventually, my stamina reached its limit. Then the old man said, 'Should I help you out?' and took out his own dick... In the end, my wife's pussy was pierced by the old man's giant cock! My wife moans more when fucking with him than with me! I just want to die aaahhhh!!
