nocturnal chipmunk 

The nocturnal chipmunk is when a male and a female are sleeping together in the same bed (literally). The male wakes up in the middle of the night, opens the female's mouth, and places his testicles in the female's mouth, causing the mouth to bulge, just like a chipmunk's mouth.

Connor and Izzy were spending the night together when Connor woke up and placed his testicles into Izzy's mouth, making a nocturnal chipmunk.
