i believe many of us have such kind of fantasy or desires. i am no different either.
Many years back, 1 day i saw my colleague bend down in front of me to pick up something. Straight away I noticed she has a nice round arse although she is d very slim n not very chio type. And at that time i fantasized bonking her.
Well, thing was really funny.... a few years later on one ocassion.... i really bonked her!!! n now she is my FB.....
