As a submissive bi crossdresser I started sucking cock from an early age. So it was natural for me to want to suck the cocks of my wife's lovers. I have done it many times.
I really enjoy when I get dressed up in my pink french maid's outfit and kneel down before him and look up at him and smile and then start making love to his beautiful cock. I like to kiss it and lick it and suck it all the way from the head down the shaft and back to the head and, as a guy, knowing all the places where the sensations are strongest. I do this until he is almost ready to cum and then I get my wife to sit on top of him. He explodes inside her and then I clean up his cock and lick all his cum out of her pussy. Wouldn't have it any other way. 😀
