I fucked my wife's friend right in front of her

So this happened while my (43M) wife (45F)’s single friend, let’s call her Debby (45F), was staying over with us on a weekend night to hang out. We all had quite a bit to drink that night. At one point I stood behind my wife, who was sitting on the couch, to give her a neck and shoulder massage while we were all chatting. She said “Oh man that feels good”, to which Debby replied “I could sure use one of those”. I told Debby, no worries, she was next.

After a few minutes of squeezing my wife I sat down next to Debby and told her to turn around. I started massaging her neck and shoulders, and also ran my fingers through her hair a little, I wasn’t really thinking. Then I started squeezing her back, playfully with gentle little pinches. When I reached her waist, I gave her a few firm squeezes with both hands, to which she reacted by righting her back, smiling and making a squeaky sound. She was really enjoying all of it, I could tell by the goose bumps, maybe she hadn’t felt the touch of a man in a while. I told her if she’d lie down I could do her legs too. My wife joked she would charge her for this and we all laughed. Then I said “you know what feels REALLY nice are butt squeezes, if you’re up for it I can give you a few of those, they’re amazing”. She’s like “Um, sure, I guess?”.

So I started squeezing Debby’s nice, round ass and both women were amazingly still going with this, must have been the alcohol and relaxed vibe we had going. As I transitioned to Debby’s upper thighs, I very lightly brushed her vagina with my index finger. She clenched her cheeks for just a second, but then relaxed again and wiggled her butt which was both cute and the permission I was looking for. I looked over to my wife, who knew exactly what I was doing because we had done the “naughty masseur” cosplay ourselves quite a few times over the years. She smiled and raised her eyebrows at me, so I knew she was okay with it and wanted to see this unfold. As I went up and down Debby’s thighs, each time I brushed her labia a little longer and with more pressure, while I was gradually parting her legs with my knees to have more access. Not long after, I was moving my index finger up and down, over the yoga pants. At this point I was still massaging her upper thigh, but I could feel it was getting damp down there. Her hips were now starting to move sexually, pushing her clit onto my finger. I pushed her legs open more until there was room enough for my whole hand.

This was getting intense, I stopped massaging and rubbed my hand up and down her vulva a few times to transition, moving on to slow, circular motions covering her meaty vagina, with my index finger on the clit. The yoga pants were getting wet fast, and her labia now felt fully engorged. I looked at my wife again who shrugged and said “Well, now you’ll have to finish the job!”. She was touching herself at this point. Debby saw it too and laughed, pushed her head into the pillow in a moment of disbelief. I pulled Debby’s ass in the air, yanked down her pants and thong. I felt my cock throbbing in anticipation of the unexpected treat. She lifted one knee, then the other, and with the pants out of the way her vagina was now liberated and ready for my cock. I took off my jeans and moved towards her beautiful ass.

Debby moaned as the tip of my cock went from pressure on the edge to slipping inside. In a few gentle strokes I made it all the way in, and I leaned over her for maximum penetration, gently pushing onto her cervix, but she didn’t seem into being taken whole like my wife so, instead I lowered myself again to stroke into her upwards, pressing my shaft up against her whole vulva, and she arched her back to lean into it. I looked over and my wife had taken her panties off and was fingering herself, rubbing her clit with her other hand. I didn’t take more than a few minutes before Debby was starting to come, she groaned loudly and so was my wife who was getting off on seeing us have sex, it was hot. I could see Debby’s hands grabbing the sofa firmly as she told me “don’t stop!” while I slammed into her. After I saw her all the way through, I offered to switch to my wife but both women had already climaxed, and told me to do the same. A minute or so later it was my turn. I pushed in all the way, pinning Debby down on my cock, my hands firmly holding her in place by the waist. I came hard in short, powerful bursts, she had reached around with one hand to hold me deep inside by my butt which was a nice, primal touch as I shot my load. She might have come a second time IDK. I pulled out and reached over to hand her some Kleenex. We were basking in the couch for a while before going to bed. This was not the last time…
