So my babes 54 yr old black sister comes to town and stays the night at our house.  She pretty hot in her own way with big 36dd tits, big but tight ass, and wearing a sun dress with a slit up the side, I've been looking at those long legs and thick thighz all night. My wife surprises me and comes out of the bedroom with some blow on a mirror. I just got her started a few weeks ago and already shes hooked but she is extra crazy and sexy when she does it. We all do some and were sitting on the couch watching tv when my wife leans over and whispers, "I'm goona get my sister to do a couple more lines, I want you to sit next to her, and gently put your hand on her thigh to see what she does. And by the looks of the bulge in your pants I can see you wanna fuck my sister huh "? Reluctantly I said if you want me to I will. But of course I wanted to fuck her, shes been eyeing my cock all night and she knows I've been looking at those braless tits also. My wife has told her stories of her fucking other men and how it turns me on, so I know this fat whore is wondering if I'm gonna fuck her to get even. So we all do some more lines, and as we're laughing, my wife said she gotta go make a businesz call, she'll be gone for 15 or 20 mins. The minute she leaves her sister said" i seen you looking at my tits and thighs, i also seen your cock get hard baby, here, look at these legs, and look,  they go all the way up to this shaved pussy". And there she was, laying back with her knees bent, dress pulled all the way up, legs apart, showing me her black cunt. I leaned to her mouth and we kissed softly, then harder, then I whispered "I'm gonna lick your pussy, watch out for my wife", and just like that I was eating my wife's sisters pussy. God was it sexy, thick lips, pink cunt, and even her asshole was sexy as I buried my tongue deep in it. I locked onto her clit, started circling it with my tongue, she held my head tight and cum super hard and was pretty loud. I sat up, pulled her dress down and my wife opened the door to our bedroom and asked whats going on. I told her it was the tv, relax, finish your call. She closed the door, her sister grabs my zipper and pulls out my throbbing thick headed white cock and just stared at it. She told me my wife described my cock but she never dreamed it looked so good. I pushed her head onto my cock and she went to town. I grabbed the blow and put some on my cock and she snorted it off, licked it, then kissed me. Fuck she is so hot. Her tits are way bigger and sexier than my wife's, she sucks my cock way better, her lips on mine feel and taste better. Within a minute she makes me cum and she takes it all.  Then puts my cock away, i put her tits back in, kiss her, we french kiss then I tell her "next time we all sleep I'm coming in to fuck your beautiful thick black body". She asked if she wasn't to fat? I whispered in her ear "darling, Im gonna make love with you like we're in love, all because I'd have no problem falling in love with you and fuck your hot thick body forever". She kissec my lips so hard, she had tears in her eyes as she said thank you for that compliment. And baby I could easily fall in love with you and that thick white cock of yourz, and Im gonna tell you right now, I am falling in love with you, my sisters husband. Let's do another line".  (To be continued)
