Guesturbate 

Masturbating when a guest in another's house. Carries extra shame but oh so naughty at the same time!

My aunt put me up in her basement for the night as I traveled through town. Couldn't sleep...I tested the bed for creaks, then naturally I guesturbated. I'm pretty sure I pulled it off without detection! yet at b-fast I couldn't help but wonder if she was looking at me funny....

Guesterbate 

The act of masturbating while staying as a guest in someone else's home. Particularly entertaining if it is in the home of someone you do not like.

Harper: "Hey Chuck, I'm going home tomorrow, so you can have the room to yourself."
Chuck: "Thanks man, but I don't need it."
Harper: "You sure? I've been around all week."
Chuck: "I'm good bro, I guesterbated in JJ's room last night while he was asleep."
Harper: "Awww man that's dirty, wish I woulda thought to do that."
