Monday's Dusk 

On the dusk of Mondays, partners will engage in such a sexual activity in which the female partner lies down. The other partner places themself in a position where their penis goes into the woman's mouth, and the male's tongue goes into the woman's vagina.

I can't wait for my first Monday's Dusk! Only two more days!
