Book on a shelf

An agreement between two best friends stating that they will not speak about a sex act committed between both of them.

Dusty book shelf

After having sex with a girl you cum on her and smear it every where.

Last night my boyfriend gave me a dusty book shelf.

I gave my girlfriend a dusty book shelf the other day.
