Id always had a thing for Angela from the very first time i met her , but being my fiances sister meant she was out of bounds. We both flirted and I always knew that id love to fuck her given chance and if circumstances where any different i would have taken her to bed. Angelas husband Jim wasn't the atentive type and i could see that Angela was less than intersted in her pathetic little excuse for a husband . That must have been what lead to her stray onto another mans cock. My wife had asked me to go get some things from town and on my way i decided to call in and ask Angela if she needed anything . Any excuse to go and get an eye full of the woman id masturbated over so many times . Even seeing a glimpse of Angeles pantie gusset or thigh as she sat opposite me in her skirt was enough to make me wank oved her. I walked up to the front door and I could hear her groaning and I immediately knew she was having sex. My cock began to harden at the thought of Angela being fucked when I realised Jim was at work , or was supposed to be. I crept up to the lounge window unable to resist peeking in and hoping to see my sexy sister inlaw playing with herself , but what i saw was a black man between Angeles open thighs as his black cock slid inside her adulterous white cunt and she told him how much she loved the way he fucked her. My cock was so hard with watching Angela getting fucked and hearing her cum on this black mans cock. I had wanted her for so long but had only been able to use my imagination and wank myself as dreamt I was fucking her . The black guy was fucking her so hard now and as Angela cried out she was cumming again , her black lovers hips lunged powerfully down between her open legs to bury his huge black cock fully inside her white body . The black man groaned loudly as he threw his head back and i knew he was cumming inside Angelas creamy cunt. Angelas body convulsed through cumming on the blacks huge cock so strongly I wanted Angela now more than ever . I waited until Angelas black lover had left and then i marched straight in. Angela never flinched and instead of trying to cover up just lay smoking a cigarette. "Did you like what you saw ?" She asked . I never knew she'd seen me aand as i struggled to reply Angela rose and walked into the bedroom . I followed and listened as she told me how her black lover had made her cum so hard. Laying on her side legs apart and knowing how turned on i was Angela continued telling me how her black lovers cock felt so good inside her. My cock ached so much with wanting her as she told of her black fuck experience and how good the black nan was. I needed her bad and she knew it. I walked over to the bed and saw her how wet with excitement her cunt was . " Did he cum in you ?" I asked . " I made him wear a rubber but I could still feel the power of his big black cock spurting his cum into that rubber me as he fill my black man loving white cunt" Angela purred , knowing exactly what effect her sexy words were having on me and my aching hard cock. At that I pulled Angelas hot wet cunt to my mouth and ate her black man loving cunt for all I was worth.
