Snowballing

This game contains at least one scene involving a sexual practice called "snowballing".

Snowballing is a human sexual practice in which one person takes someone else's semen into his or her mouth and then passes it to the mouth of the other, usually through kissing.

The semen may afterwards be returned to the partner's mouth, mixed with saliva; the couple or other partners may then exchange the fluid several times, causing its volume to increase (hence "snowballing").
