I remember Lynne walking in on us one night, we were both stark naked on top of bed, Sandra was sat on my cock facing away from me towards the door that Lynne walked through. We were being a bit noisy as it was one of her favourite positions, Lynne must have been woken by us and had a good view of my stiff cock as her mum got off.
Lynne got into bed with us, we all snuggled up on our right hand sides, with Sandra in the middle, I got a bit touchy feely as Sandra was obviously still aroused and she let me enter her from behind.
Lynne just had her short nightie on and was pushed back into her mum. I had my left hand over them both resting on Lynne’s tummy and my right arm under both of their heads. Sandra had put her left hand back and guided my cock, which was very stiff and sticky from earlier penetration, into her then put it back round my bum and pulled me in. I was gently, slowly pushing in and out, kissing her neck and rubbing Lynne's tummy at the same time. I couldn' t thrust in case she got scared at the movement so I was very gentle. My cock was really thick and feeling like he was being sucked hard by her, the neck of her pussy tightened like a rubber band round the base of him.
Sandra's hand came back and rested on top of mine which I let lazily rub up and down Lynne's tummy in time with my short thrusts. I was able to gradually feel her boobs and was just grazing over her nipples, returning to her tummy so as not to make it too obvious. I could feel Sandra contracting her bum to squeeze me and also sensed she was getting agitated and frustrated.
I let my hand drift downwards onto Lynnes bare thigh gently moving it back up bringing the edge of her nightie with it. Left it there for a few moments in case either resisted, Sandra's hand was still on top of mine, our fingers intertwined, she squeezed my hand as I slid up under the edge of the nightie onto Lynne's bare tummy.
I let it rest again and concentrated on my cock inside her, I was flicking it upwards, wiggling it inside her, rather than thrusting, letting it grow. It was pushed down at an odd angle because of the cuddling so was hitting her front wall consistently which had Lynnes bum snuggled tightly up against it the other side.
