My bf and I have been together for 5 years and have recently gotten into exploring our sexual fantasies. He’s been my cuck for about a year now letting me fuck other men as he watches & takes care of me after. One night we were talking about people we were interested in hooking up with & 1 jokingly mentioned his uncle. He’s a good looking older guy, muscular & 6’3. My bf said he thought it was weird but understood bc of how good looking he was. A few days later my bf surprised me by saying he had asked his uncle in a sly way if he was interested in fucking me and he had agreed to it only if my bf wasn’t there watching (he felt awkward about it). He came to our apartment that weekend while my bf was out and we had some really good nasty sex. After a good half hour of 69 he was pounding me from behind raw. Reverse cowgirl was our next position with my tits bouncing as he pumped me full of cum. We ended up going a few round as his balls hadn’t been emptied in a while. I enjoyed sucking on his huge balls & deepthroating his cock as he moaned my name. After being filled 3 times by him he finally said he had to leave. My bf returned immediately & started getting to work licking & cleaning my pussy, eating his uncles cum loads out of me
