John was wanking off in his room but was in sentry mode so he could hear if his housemates returned.

Senura

The Unholy Brown Devil. The Senura is an immortal being of legend that has walked this earth since the dawn of time, he is well versed in the fabled 'brown magic' and is known to emit an unholy presence. His piercing stare is known to chill people to the bone and send them into a trance like 'psychedelic' state, with many women falling in love with him on the spot. He has taken on many different appearances through the years making it hard to give a definitive physical description. The Senura is a magical being of legend and if one were to exist, it would surely be forgotten very soon.

Girl: OMG who is that tall dark and handsome guy over there?
Girl's BF: I can't believe what I'm seeing, I think that may be the Senura the Brown Devil, he isn't supposed to exist.
Girl: breaks up with BF and asks the Brown Devil for his number.

The Sentry Gun

An ancient bathroom ambush tactic. The operative will wait in the middle stall for 2-3 people to start using a urinal at once, it is imperative to this tactic that the urinals have no surfaces or walls separating each other. Once they start urinating the operative will burst out of the middle stall and grab the middle urinal user in a chokehold while also shoving their knee into their ass. The knee in the ass will enable the operative to maneuver the still pissing victim into the same direction of the other urinal users like a sentry gun, if successful the victim should piss all over the other users. (Optional) If the victim is uncircumcised hold the foreskin shut, once it fills with enough piss let go, this will release a charged shotgun blast of piss, this increases the spray factor enabling heightened efficiency in combat situations . Once the victims piss stream is weakening then it is imperative that the operative must retreat before the other urinal users start pissing on them, if necessary use the victim as a piss shield. To create a distraction pull down the victims pants and shove them into the closest user. The user closest will begin to freak out as a piss covered dick is rubbing up against their own piss covered dick. The furthest away user will be blinded by not only the display of violent dick rubbing but also the victims bare ass. Operative is urged to flee at a designated rendezvous point to await further orders.

"Dude, the urinals open, why aren't you pissing with me?"
"I don't know man, middle stall is occupied, I think someone is trying to use The Sentry Gun on us..."
