Mystery Son 

A game in which three males ejaculate into separate cups, and three females have to randomly choose a cup and turkey-baster it into their vagina. 9 months later, the females have to guess which male spawned their newborn child.

"Hey Kerri! How about you and Jasmine and Bella join John and Kyle and I for a game of Mystery Son this afternoon!"
"Sounds like a plan! Hope I get you!"
