I know this scenario well. Wife left me for 20 minutes to walk down the street and get pummeled by a superior cock. I always assumed he either used a condom or pulled out and spunked on her luscious body. But on this night, he apparently unleashed his massive load in my wife’s asshole. When she got back home, she didn’t say a word. She just sat on my face and I began to worship her pussy. About a minute later, she was demanding that i lick her asshole, which is not her normal request. As soon I started to lick it, she began bucking wildly. She started moaning and asking if I could taste it. I muffled a reply that was something to the effect of “taste what?” She replied in screams as orgasms ripped through her body….”It’s his cum. He cam win my asshole. Lick it all up you loser. Oh fuuuuuuuck.” The power of forcing me to swallow another man’s cum from her tight little asshole took her to a new level of dominance that night. I had never seen her cum so roughly and powerfully from any sort of anal stimulation in the past, so it was clearly that stimulation combined with the overwhelming sense of power that made her quake with fierce orgasms on my face.
My wife makes me eat it or use it as lube to masturbate with. Either way I get to enjoy superior semen.
