Yeah, that's an interesting position. There used to be a site that featured funny/interesting sex positions - I saw that one on there. Another one was a circle of girls all wearing strap-ons. The girl behind was banging the girl in front of her, who was banging the girl in front of her... so on and so forth - and they went around til the circle was complete.
I think more **** would become interested in geometry if teachers would use visual aids like that. :dunno:
