Doing the one and only to, and with yourself when your SO or GENT walks in?  Do you ask them to join, or do you just continue feeling groovy?  I think I'd be the same with both, a little touching might be necessary.  Would you rather him/her watch, or just say, baby let's get after it?   It's always more fun with a willing participant!  Does the fact you got caught turn you on?  I think it's HOT!  

I was getting a handjob from a fbsm provider when one of the other ladies needed to come in and talk about a client problem. I told my lady I was fine with her watching.  The lady came in and acted all embarrassed about interrupting us.  I would have been happier us she acted nonchalant or even interested in watching.  Oh well, I still enjoyed it.

I've always been turned on from mutual masturbation (back from my college days, I had a girlfriend that really got hot if I started masturbating in front of her, it usually started from her changing clothes in front of me) I've been looking for a chance to re-explore that whole scenario but... I got married and had children...

It's hot to watch or be watched, better to jump in or have someone jump in.  I mean, how cool is it to know that you turned someone on instantly and they want to join in?

I appreciate the comments.  I need to get ready for another impromptu and sexy OOPS!    xo
 Go forth and f*ck America!
