Fucked my bbw sister in law

I've never been that attracted to my sister in law Becky. She's 35 bbw nice but not really my type...until the last several months after I had an erotic dream about her. I wasn't obsessed about fucking my wife's younger sister, but after I thought about it, I decided that if it ever came up, I'd fuck her...or at least mess around with her, maybe a blowjob or a nice make out session. Anyway, Becky had a fight with her husband, and was staying at our house for a couple of days until things blew over. I had a comp day off one of those days and my wife was at work...Becky was there so we chatted for a while, sitting on the couch then we got to flirting. I moved closer to her and put my arm around her shoulders...she snuggled in closer we made eye contact and then we kissed. A nice long sensual open mouth kiss our tongues tangled...my hands went down to her breasts. She whispered "oh my god! I can't believe this is happening! I've wanted you so nice I first met you!" I then whispered to her..."do you want to go upstairs with me?" To which she replied "oh fuck yes!" I took her hand and led her until stay R's to the guest room where she was staying...we started kissing and removing each other's clothes. We were naked and kissed by before the bed...Becky reached down and started pumping my hard cock whith her hand...before I knew it she was on her knees giving me an amazing blowjob...feeling her tongue on the shaft of my penis and all the way to the base of my balls as she licked and sucked me feverishly. I pulled her up to me, kissed no her deeply while I squeezed her bare tits in my hand. Then reached down to grab her ample ass. She whispered to me "I've always wanted to suck your cock! It tastes better than i ever dreamed..you can cum in my mouth if you want.., I'll swallow every drop. I told her I have a better idea of where I would like to deposit my cum...I turned her around and bent her over the bed..her round big ass sticking out towards me..."oh fuck me!!! Please fuck me!!" She moaned...I Inserted my hard dick into her very wet pussy...she let out a loud moan as I entered her...I started slow rocking my hips and thrused my cock further inside her...she moaned "oh god! Oh fuck yeah! FUCK ME!!" I do d as she asked moving faster hearing her moan and then she yelled "oh fuck!! I'm cummmmmming!!!!" I felt her rock as she slipped into an intense orgasm..it was all I could stand I felt it building upo and I let it loose...pumping my semen into her pussy yelling out "oh fuck Becky I'm gonna cum!" I pumped like a madman still thrusting inside her as I did, that's when she came again..."FUCKKKKKK!!!" She yelled "DONT YOU *************** NOW!!! IIM CUMMING AGAIN!!" When we were both done I collapsed on top of her, kisses on the back of her sweaty neck....we dressed and went on with our day. I did ask her about birth control, we didn't use a condom and I was a bit worried that I may have gotten her pregnant...she said she was on the pill, much to my relief. Neither of us spoke about it for a couple of weeks, until she sent me a text asked me if and when she could have me again. Hopefully soon
