DVDMS-355 College friends locked in a room until they collect 20 ml, the game turns into raw sex

Four pairs of male and female college students are asked to join a challenge: they cannot leave a locked room until they fill a container with 20 ml of semen, using only hands or mouths at first. As the game goes on, the couples start having unprotected sex, and the footage shows how the prize-money game shifts into mutual desire. Released in 2019, the video runs 142 minutes.
