Hands free orgasm

[Cock4panties]

So, I've spent the morning / afternoon sneaking looks at sissy porn tumblrs and my minds been racing most of the day. I had to go to pick something up from reception and spotted a pretty girl who works behind the desk, as I was walking away I thought how awesome it would be if I discovered she had a nice hung cock too as I'm walking I get a wave of tingling in my cock, I held on to the sensation and tenses my cock a few times as I walked back to my office, it was like a mini mind only orgasm... Ever happen to anyone else?
