Bra wanking

I've posted about this before, a friend of mine, my jack off buddy and I use his wife panties to jack off with, she is ok with this as long as we toss them in the washer when finished, she sometimes comes through the den where we are at and watches for maybe 1 minute. I began to want to jack off in her bra, she has nice tits, her husband got her permission and she even thought it was a turn on to know that I did this, her husband invited her to join us, she did after a few weeks, she came in topless, we ended by both of us shooting off on her tits, she would lick off some of the cum, her husband would then use a dildo on her as I watched, all very good.
