jack-in-the-bed

When your man TRIES to discretely jack-off next to you in bed, thinking you're fast asleep, when in all reality, your laying there quietly, as the mattress gently, yet distinctly begins to bounce slightly, then more and more rapidly until he finally gets it done or until you kindly ask if he would like some help.

I get secretly turned on when my boyfriend plays Jack-In-The-Bed.
