A beautiful wife is asked to try an escape game to collect semen, but she gets excited by a big dick and cums inside

The beautiful wives they picked up (Tsubasa Hachino, Kaoru Kira, Iroha Maeda, Azusa Tani) are asked to play a game where they can't finish until they've collected 30ml of semen. They try to milk the sperm out of the sexually troubled male students with handjobs, but they can't resist the temptation of their big dicks and end up having raw sex and creampieing them!
