Jack Off January

As compensation for participanting in No Nut November, which is harder than you think, you can also participate in this event where you must nut every day in January. It’s certainly an easier challenge, it probably happens every day tbh... just follow it and you’re a good person.

Cisgender Male 1: What do you plan to do during January?
Cisgender Male 2: I’m going to do Jack Off January.

Jack's Mannequin

When you give someone muscle relaxants instead of a rufie. Then you rape them while they're still fully awake, but unable to resist.

"Uh oh, I can't move my arms or legs... did you put something in my drink?"
"Yup, and it looks like it's kicking in, so now I'm going to drag you out back and give you a Jack's Mannequin"
"God damnit! Why can't you just slip girls rufies like everyone else, you sadistic bastard?"
