My wife and I were down visiting her sister who was recently divorced. She was happy to be rid of the ass she had been married to, but of course it was still a difficult transition for her. Apparently she hadn't been having sex for several months. My wife is 43, 5'6", weighs about 145 with a little tummy, a soft tiny ass and 40F tits. Her sister is 46, 5'8", weighs about 155, a little more curvy with a full round ass and 44G tits! They are also both half Japanese, so very exotic looking. I've always had a thing for her sister and would often jack-off thinking about fucking her.

It was a long drive overnight to get to her sisters house and we didn't get there till early afternoon but decided not to sleep until that night. Her sister always takes Ambien to get to sleep, as does my wife once in a while. Some of the most incredible sex we have ever had is when she is on her sleeping pill - just about all inhibition goes away when she does. It's also very common to have "Ambien amnesia" and not remember the night before, so I can get away with more than I ever would with 'regular' sex. So after the two of them do some catching up, we have some dinner with a couple glasses of wine. About an hour after dinner, they both decide they want to get a good night's sleep so wife and sister both take a sleeping pill and get changed for bed, my wife in a long t-shirt and her thong undies, her sister in a teddie with silk shorts. They decide to do some more chatting before the pills take effect, which doesn't take long at all with the alcohol in their system. As they are sitting on the couch talking, they are both getting more giggly and dopey. I notice when her sister shifts on the couch, her silk teddy bunches up and I can see full on shaved pussy lips. I've already been getting horny as hell cuz I know I can get my wife to have some crazy sex, but seeing her sister's pussy instantly starts to get me hard. I know I'm not going to be able to keep composure so I walk up next to my wife and jokingly say, "let's get you upstairs so I can take advantage of you." They both laugh at that. My wife tries to get up and falls right back on the couch. They both laugh some more and my wife looks up at me and says, "I don't think I can make it up, you'll just have to take advantage of me here."

My mind starts racing and I'm getting harder by the second. As her sister is looking on (me looking back and forth between my wife, her sister's pussy, and both of their massive tits), I start thinking 'what the hell, they (hopefully) won't remember this in the morning' so I pull down my shorts and pull out my hardening cock right in front of my wife's face. Without missing a beat, my wife takes hold of my cock and guides it right into her mouth. Her sister gets this wide eyed look on her face and then leans a bit forward so she can see my growing cock sliding in and out of my wife's mouth. I'm watching her sister as I'm getting my cock sucked and she is starting to breathe a little heavier. After a couple minutes, rather than blow my load and end the fun too soon, I pull out and kneel down in front of Jan lifting up her t-shirt above her tits and pulling her thong down exposing her shaved pussy lips. I start squeezing and sucking on her massive tits as I work down her belly to her mound and begin spreading her pussy lips and licking up her wet slit. I finger her pussy hitting her g-spot as I lick and suck on her clit. It takes a few minutes because of the wine and sleeping pill, but she is soon arching her back and moaning heavily as cum oozes out of her pussy getting the cushion wet. As I lift up and slide the head of my cock up and down her pussy getting ready to slide it in, her sister is almost panting and has pulled her enormous tits out of her top and is pulling and pinching her huge eraser nipples. I slowly slide my cock in my wife's pussy and her sister reaches down to pull her shorts aside and starts playing with her pussy and rubbing her clit. I'm reaching up and playing with my wife's tits as I'm sliding in and out of her slick wet pussy while watching sis fingering herself. I'm not sure how much longer I can hold out. I don't want to get caught staring at her sister as I'm fucking my wife, so I turn her over on her knees and enter her from behind. Now I'm free to watch her sister playing with her slit as I'm sliding in and out of my wife's pussy. I can feel my nut building as her sister makes eye contact with me. She is almost over the edge with her own orgasm so I took a chance and reached down to finger-fuck her pussy as I look at her and quietly say, "I want to cum in your mouth so fucking bad!" That puts her over the edge as she damn near squirts her cum on the couch and floor. As she comes down from her orgasm, she looks over at me and licks her lips. I take this as a 'go ahead' sign and as my balls tighten I pull out of my wife's pussy and stick it right in her sisters mouth. She begins to suck me off as I unload shot after shot of my cum in her mouth. She swallows my entire load, then begins licking up and down my cock getting all of her sister's pussy juice cleaned off me. Cock in her mouth, my wife works her way to stand up and turns around to give me a kiss before stumbling around heading to the bedroom. I'm shocked as hell that she either didn't see my cock in her sister's mouth or didn't care, but I watch her shuffle off toward the bedroom as sis continues to work my cock in and out of her mouth not really letting me soften.

If you like it so far, let me know and I'll tell you what happened with my sister-in-law afterwards
