Snowballing

I've been jacking off in the office over my office manager.  She's a really sweet country type girl with a nice pair of boobs, a slightly big but nicely shaped ass, blonde and a very sweet smile.  We talk a lot and get along great, and I've really got an urge to fuck her.  Well, can't really do that so I jack off while she's on the other side of the office partition.  I've smelled her panties and jacked off on them when she changed clothes at work to go to a swimming work out right from the office.  She smells like a mix of sweet fruit from her soap and a nice earthy pussy smell.  

I've got the fantasy of her mouth on me as I jack off into her mouth, and she sucks on the head of my dick until I come and then snowballs me to share my cum.  I also whack off thinking about eating her out and then sharing her cum with her.  She's talked to me about sexual things with her husband and one was about his cumming in her mouth.  She likes it, he has troubles with it.  I've whacked off and dripped some cum into her cocoa and a couple of times in her bottle of water that she keeps on her desk and then I watch her drink it.  I think she knows, but am not completely sure.  All I know is when I do it, she comes over and yacks with me while she's drinking from her mug or the bottle of water.
