Ummm,,, no no no. Unbelievable as it may seem, a boob beating has no resemblance to a spanking.
Everybody just calm down!! :-)
There was a strip club that had this old woman as a waitress. She was around 65 and she had these real long boobs if you know what I mean. She wore a shirt with holes cut in so that her boobs hung out. She would hit people with them for money. Well, we tipped her to hit this one guy that was hanging around with us. she reared back and SLAP, that boob broke his glasses and his nose!!!
Bikers do funny things for entertainment!
