When you bust your nut solely from stroking your meat between the ass cheeks of your partner. There’s no penetration. Just friction from that ass crack.

I did the old crack jack last night and nutted all over the small of her back.

I did a crack jack last night with no lube. The skin to skin friction was intense.

bloody jack

Jacking off so much that your penis starts to bleed. Although it is bleeding, you continue to jerk it and jerk it and jerk it until all of the skin comes off like a peeled banana. Usually done in front of a crowd.
