When a girl sits on
a guy's penis (so that his penis is up her butthole), she starts spinning in circles while she is still on him. During this, the guy starts
moaning sounds similiar to those made by an
electric pencil sharpener.
Friend :
Hillel, did you and Beverly do
the pencil sharpener?
Hillel : Why, yes! We did do some pencil
sharpening of our own. I also got the moaning sounds down perfect, Zzzrrrrrr Zrrrrrrmmm
Friend : Thats great, maybe Beverly will pencil sharpen me too!
