Deep skin docking 

deep skin docking is essentialy the deepthroat action of docking, where the foreskin of one males penis completely engulfes the penis of another male.

I was surprised by how stretchy his foreskin was when he decided to perform deep skin docking on me during our fifth intimate docking session of the day.
