As my mind and body drifted back to reality Sandra had got out from under me and was now standing behind me caressing my ass. She leaned forward and said to me "God how I want to fuck you doggy with that strap-on of Jane's." I told her to fuck me now but she again refused until after the baby was born. But she did say that if I could get it on I could fuck her with it. I don't think I have removed my clothes faster than that day. It was a tight fit but I eventually got the harness on. But I was in so much of a hurry I forgot to fill up the dildo. Sandra was in the middle of removing her wet cloths when I told her to leave them on, as I wanted to feel them against my skin. I also told her that I needed her to fill up the ball sack. So she took it and pushed it up into her pussy and filled it full of her piss. She handed it back to me and told me to fuck her slowly because she didn't want me to exert any extra pressure on my pregnancy. She also said that if Jane knew that she was letting me do this she would freak out. I asked her where she was and she told me that she had a business meeting in town and was hoping to be back for our little session.
I bent down behind her and started to lick her pee-covered pussy getting her all juiced up ready for my very first dildo fuck. Sandra couldn't help herself as she released a squirt of pee into my mouth. God she tasted so sweet I just wanted to stay there all night but I had other "pressing" matters to attend to. As I backed away from her I also spat on her asshole just like she had done to me earlier. I started to rub my thumb around her ass as I slowly started to insert the strap-on into her waiting pussy. Sandra let out a low moan as I pushed the dildo deeper into her. I started to hump her slowly as I pushed my thumb into her ass. It was a strange feeling actually fucking another woman. It was very hard to get the rhythm right but after a while I managed to get it going. I was difficult with my pregnant belly in the way so I got Sandra to lean forward on a little stool so her ass was poking up in the air. This gave me the access that I need. I was now able to go harder without straining myself.
As I drove the dildo deeper and harder Sandra started to grunt at me " God fuck me harder Michelle fuck my cunt you horny pregnant bitch." I started to feel my thighs getting wet from my own juices running down my leg as I pushed and twisted my thumb deep in her ass. I could feel Sandra pushing back trying to get as much of it into her steaming slit. Then suddenly she yelled out that she was going to cum and cum hard. I told her I was going to cum with her as I reached down and started to squeeze the fake balls full of Sandra's piss. Her body went stiff as her orgasm ripped through her. I was now pumping the balls forcing all of her piss back into her pussy. I tried to pull my thumb from her ass but she had it clamped in there until she was ready to release it. I could feel her pee splashing back on me as she was riding the fake cock. I had become just a bystander that the dildo was strapped to - as Sandy screamed and shook through the biggest orgasm I had ever seen her have.
Sandra's body finally went limp as my thumb was released from her tight grip and she slumped on the floor in front of me. As she fell forward the dildo popped out of her pussy releasing the final squirt of pee onto her upturned butt cheeks. She was breathing so hard I thought I might have to give her mouth to mouth or something as I sat down pondering what had just happened. As she recovered and sat down on the chair next to me Sandra told me that she had never experienced anything like that before. I told her it must have been the thought of an 8-month pregnant woman fucking her brains out that made the difference. I told her to get out of those wet cloths before she caught a cold. For the next half-hour or so we just sat chatting as we drank to replenish our fluids. I still needed to have the ultra sound I reminded Sandra. So I jumped up on the table naked as Sandra naked herself proceeded to do it. I asked her if this was the first one she had done naked and she just laughed at me.
Just as Sandra had finished the door opened and in walked Jane "Good I thought I might have missed all the fun" she said as she walked over behind me unbuttoning her slacks. "I've been caught in traffic and I haven't peed for 4 hours and I'm busting" she said as she straddled my face and let go a full bladder of hot golden piss right onto my face and in my mouth. As Jane was filling me up at one end I was emptying it out the other end into Sandy's mouth in more ways than one. Two hours later and after another 3 orgasms we were all ready to leave. The girls said to me that I had no need to return for another ultra sound as in another four weeks or so I would be giving birth to my beautiful son Josh (the best day of my life). But at anytime I wanted to return for a "follow up" just ring and book a late session. To this day I still see Sandra and Jane at the clinic and privately as well and all three of us share something very special. These two women have opened up a side of me that I never knew existed and I'm eternally grateful to them. I only wish I had found out about lesbian sex and watersports earlier in my life. My husband still knows nothing about any of this and thatβs the way I like it.
Again I'd like to thank all the people that Responded and any feedback on this chapter would be appreciated. Also any and all encouragement required if you would like to hear of any more adventures between the three pisscatears.
