it described a woman (actually an 18-yr old) haveing sex with a group of men... she took one up the ass, on in her vagina, one in her mouth and was giving two handjobs with each hand... a couple of other guys walk in and she invites them to participate... when one asks how... where to place his penis... she suggests they put them in her armpits....  

Well, ever since... I've found armpits to be  somewhat erotic... and I've noticed that I have a grip that I put on strippers.... when they lapdance for me... they literally drip from their armpits... and really seem to get into the "dance" ....   yea... funny what appeals to different folks... just never got into the foot thing....
