On Phone During Blowjob

Almost 30 years ago I had a one-night stand with a somewhat wild woman, she had a couple kids at home and we met through one of the phone dating lines that were around at the time. She couldn't go out with the kids to take care of, so she invited me over and made it fairly clear that she was lonely and looking for a booty call. Margaret was mid-20s like me, had dirty blonde hair and an average build, neither very good nor bad looking, but with a fairly direct, tired, no-nonsense attitude.

Within an hour we were in bed together, fooling around, she laid on her back and I was sucking her nicely-sized tits while she gently stroked my hard cock. Suddenly she got a call from a girlfriend who asked her how her date was going. I couldn't hear the friend, Sherry, as well as I could Margaret (this before you could put a phone on "speaker" mode), but I could figure out the conversation from the one end. "Yeah, pretty good looking." "Well, he's fucking my tits now." (I was, switching to this to keep my penis happy once she had gotten distracted by the call.) "Plenty big." (She looked down to check as I thrust toward her.) "Do you want to talk to him?"

Margaret handed me the phone, I was smiling and laughing a bit at this situation, and Sherry obviously found it funny as well, though there was also an earnestness to her voice, she was clearly a trusted friend who shared intimacies with Margaret. I held it in one hand while I braced myself against a wall with the other, tensing to keep myself stable on my knees while Margaret started working my cock and balls below me.

"Hi Steve, are you having a good time? You taking care of my friend Margaret?"
"Well, I'm trying to, though right now she's taking pretty good care of me."
"What do you mean?"
"She's..."--I had to pause here to retain my composure--"jacking...me...off...right now. And it feels great."
"Is she good at that?"
"Yes...oh my."
"What was that?"
"She's sucking my cock right now." I had lifted myself slightly and moved forward so my cock was closer to Margaret's face, which she took as an invitation to envelop me between her lips, and her method was clearly speed--she was sucking and jacking me FAST like there was a deadline. I was now just gasping and whimpering while Sherry was teasingly trying to talk to me like I could coherently respond, probably greatly enjoying hearing how I was completely overwhelmed with pleasure. "I'm going to cum Sherry."
"Oh my god, are you going to cum in Margaret's mouth? Are you cumming in her mouth now you dirty boy?" And I was holding onto the phone and wall for dear life, grunting into the phone as I squirted between Margaret's lips. I felt simultaneously overwhelmed with pleasure and powerless, trying but failing to maintain my composure on the phone. I handed the phone back to Margaret. "Of course." "Yeah, it was fine." "Ok, then."

Margaret hung up, and we laughed together over this. We fucked a little, did more oral sex in the morning, and then parted ways. I never saw her again or met Sherry, but often fantasized about phone sex with her or having her watch me jerk off or cum in her friend's mouth, though I have no idea what she looked like. Which probably makes the fantasy better in some ways.
