Cybersex becomes real sex

Many years ago when I was in my 30's I used to frequent cybersex chatrooms. It was all new and exciting back then and after chatting to Sam online for just a couple of hours we were both so turned on she suggested we meet an I agreed without hesitation.
I was never expecting to actually meet someone for real but here I was driving to a carpark to meet her and her husband Geoff. Sam sat in the car and Geoff cam over to talk to introduce himself and mention some rules. Well one rule really. Sam didn't like having her nipples pinched and so I agreed not to do that. That was when Geoff mentioned that Sam was pregnant and asked me if it was a problem. I had never had sex with a pregnant woman before and to be honest the thought excited me so I told him no, it was fine.
I followed them back to their place and my heart was racing because I had never done anything like this. They invited me in and we sat on the sofa chit chatting for a while. I was wondering how to this was going to happen when Sam stood up and left the room.
I was thinking I'd blown it as Geoff said "Sam and I are going to go in the bedroom and if you feel like it you can join us
I watched as Geoff followed Sam into the bedroom and I took a few deep breaths before getting up and joining them.
Sam was laying on the bed naked and I could see how big her belly was. She must have been very close to 9 months because when I called Sam a couple of weeks later, she told me she had just given birth.
I got undressed as Geoff was eating her pussy. I walked over to the bed a little unsure what to do. "Stick it in her mouth" said Geoff.
I knelt down and put my cock between her lips and slowly pushed it in.
Geoff's instructions were turning me on as Sam sucked and slurped on my dick. Meanwhile Geoff had already started fucking Sam while she worked her magic on my shaft. Geoff must have enjoyed the sight of it as much as I was enjoying Sam's expert sucking because he came not long after.
He pulled out of her and suggested I grab a condom from the bedside table. I slipped it on and positioned myself between Sam's legs.
I was actually a bit nervous as I slipped my cock inside her. I stopped as she moaned and asked her if it was ok. She smiled and gave me a kiss and nodded.
I slowly slid all the way inside her and held it there. It felt so good.
Geoff knealt beside her and offered her his cock to suck which she did enthusiastically.
I slowly fucked her and she started pushing back against me.
She moaned around Geoff's cock as I fucked her harder and faster.
Geoff played with her tits as I felt myself getting close
Sam was flicking her clit as Geoff moaned and came in her mouth.
Sam gulped his load down and she started to cum herself. I was only a few strokes after her and i held my cock deep inside as my cock twitched and spurted inside her hot wet pussy.
We stayed like that for a minute or two and then I slid out of her and sat back on the bed and smiled.
I excused myself and went to the bathroom to dispose of the condom. Geoff met me as I was coming out and said "Hey, feel free to grab a juice from the fridge before you go". I took that as my cue to leave. I poured myself a glass of juice and stood in the kitchen listening to the sounds of their lovemaking. I finished my juice and placed the glass on the counter before leaving.
I drove home excited at what had just happened and how totally unexpected it was.
