Swedish teacup 

When a man and two women partake in a three some, the man pulls out and fills one of the women's navels with semen. The other woman then slurps the semen out in a similar fashion of a body shot.

Dude I finally got mary to agree to a three some and she totally let me Swedish teacup susan.
