I've been in about, oh, I'd say 10 MFMs with my wife. I've been off to the side watching her with others maybe another 8-10 times. She's only been with 9 guys in 4 years but of those guys, 7 have been repeat visits with 3 of them having been repeat visits MANY times. So all in all, 90% of the time I'm not there. But this time I was.
There was one time where her and a boyfriend of hers - they had an on-going thing for a few months, he was much younger than her. I was there kissing her at first, massaging her breasts, but this was one of the few times she let me watch so when they ramped it up, I moved over to the side and nervously sipped my drink and watched.
They were having sex in the missionary position and she had already cum several times. He had really given it to her the whole time. They had flipped around doggy-style and I watched her face contort while she was facing me, she got on top and bounced on him for a while, (she's got nipples that are very sensitive and so when he sucked on them she went nuts). They were panting and sweaty.
They ended up back in missionairy after she blew him for a little bit but the look on her face was no longer overly lustful, she wasn't being overly vocal with moans, but she had a motherly look about her, a nurturing look, a look of compassion and almost a curious sympathy even...they had been going at it for almost an hour in various positions and sweat was pouring off of him, his face was grimacing and you could tell he just really wanted to cum but was having a hard time bringing it on. A good problem to have!
In a soft, caring and nurturing voice - not some porno star, explicit, and abrasive tone - but something far more caring, she was begging him to cum. Softly speaking to him, "You're almost there, come on, you almost have it, come on, cum in me," as she gently dragged her fingertips down the side of his face, looking up directly at him. As hot as that all was, that's not even the part that sticks out.
What sticks out was when he eventually came and her mouth was open just a tad to let out her silent gasps as he thrust hard into her, exploding into her, he was moaning loudly, like a guy does when you can't cum and you have to work hard for your orgasm. And as he exploded, he was very close to her body as it was but since cumming he had half collapsed on her, and her hands wrapped around his neck and back and she was rubbing him like a mother would to a sick child, or like a wife would to a husband if he were upset and in need of a hug and nonsexual affection, almost as if to say, "There you go, that's it, let it all go."
It was very sweet and like I said - she seemed genuinely concerned about his pleasure in a very empathetic and tender way. The whole ordeal seemed very nurturing and sensual.
But it didn't take long for her hands to make their way down to his ass and you saw her pull him deeper into him and thrust her hips up at him as she urged him on to start thrusting in her again and he did. And I don't know if he was going soft or not, or if he got hard again, but he started full on fucking her again. I wasn't up close, but I could see his cock and balls were soaked with THEIR cum. About 3-4 minutes into it she screamed the loudest I've ever heard her scream while she came a final time, and that threw him over and he added a second load into her, to add to his first.
After they lay there for a bit, holding each other close, trading a few pecs on the lips, he pulled only half way out and she told him to hold on, reach down and massaged his balls for a short while and made slow milking strokes onto his dick to make sure he was fully drained.
She's done this same thing with me a few times, I don't know if it's an act or not, or if it was an act of genuine empathy there for a guy having trouble cumming - but seeing her do all this with another guy? Mind blowing.
There was nothing really kinky about it. Just seeing how hard it was for him to cum and how nurturing she got in coaxing it out of him, and how that in of itself made her explode and him explode a 2nd time ... sexy as hell.
