Fucking My Daughter In Law

So the last confession I did was several years ago about my friend 'Jen' who Ive now gotten into a full blown relationship with after breaking up with my longtime GF from that confession. And while, as before our sex life is good and I haven't strayed at all, but somehow I ended up fucking her oldest daughter. She has 3. Oldest is 22 there is also a 17 and 16 year old both of which I'd happily fuck but only after they're 18. Never in my wildest dreams did I expect this to happen and didn't really do anything to encourage it, it just kinda happened spontaneously. Just to clarify I didnt raise this girl so we dont have a father-daughter bond and I didnt groom her or some other crap. DIL lives several hours away with her BF who's a typical young guy and does young guy dumb shit. They're young parents and have the typical young folks issues which Ive helped with when asked. Its honestly not alot as they try to do it on their own steam which I respect. This particular time we were visiting as we do from time to time. My GF recently has developed some heart issues and takes a few new medications for it which really knock her out. So it was mid afternoon and she was passed out in the guest room. I was coming out of the room after checking on her and DIL was watching TV. My grandson in law was napping and the BF was mowing the lawn out back. They live in the country and have a fairly large backyard so it usually takes awhile. He's been saving for a riding mower but was at this point still using a standard push mower. I settled down next to DIL and she was watching re-runs of top model or some crap. We were chatting and she was complaining about SIL saying he doesnt help after he gets home from work and the age old young folks arguments. I was giving her the best advice I could just trying to lift her spirits a bit but she kept coming back to "I wish we were like you and mom, you guys are so into eachother" which I cant really refute. Then she asked in a hushed tone "How often do you guys do it?" she said kinda giggling. I did the turkey peak and told her the truth. "Two or three times a week" she just laughed and said "wow thats more than me and SIL" I said "really? you guys are young you should be banging alot" she just kinda frowned and said "After GSIL he hasnt looked at me the same, I used to be tiny like mom but now Im a bit bigger" which was true but she still looked pretty good. She was maybe 10-15 pounds heavier than she used to be and had some baby damage because she was tiny her belly had some stretch marks which I saw when she was wearing a swimsuit or was reaching for something and her shirt rode up. Then she said "so yea we havent done it much recently, so whats mom into is she a freak?" I was laughing and said "not really we're pretty vanilla actually, no whips or chains" she kept giggling and the conversation just turned into favorite positions. We were talking in hushed tones and she was laughing, a few times I was talking I caught her biting her lower lip and I wasnt going into great detail just general stuff. She was definitely turkey peaking out the window checking on SIL's progress and said "Me and SIL havent done in it in like 3 weeks and its driving me nuts" she said with a heavy sigh. I said "his loss, you look pretty good still" I said and I put my hand on her back. She said "you think so?" I said "definitely" and I patted her thigh. The last pat I let it linger for just a bit and she was quite literally staring at me right in the eye. I was thinking "is this about to happen?" when she kinda blinked and got up and said "you want something to drink?" Now Im not a fool I knew she was on the verge. I didnt answer her and just followed her into the kitchen she was leaning into the fridge with that great ass sticking out and I just came up behind her and I thought "Im about to fuck her or fuck up my life" and went for it. I put my arm around her waist from behind, and I felt her kinda lean into it and she said "what are you doing?" I just pulled her back into me and said "you know damn well what Im doing" and put my other hand under her chin and pulled slightly back on her neck making her stand up straight and I immediately slightly kissed the back of her neck. She moaned and said "God Im so horny" and I said "So let me fuck you" and she practically melted and spun towards me and started kissing me on the mouth and pushing me back slightly so I bumped into the doorway between the kitchen and living room. Part 2 on the way.
