Slipendictomy

To stealthily insert one's member into one's partner's orifice, typically occurring in the morning.

I woke up with a raging boner and only 20 minutes to get ready for work. Foreplay would take too long and waking my partner would be bothersome. If I was to deswell my throbbing member, it was critical that I perform the slipendictomy quickly.
