She carried on with her hands and she realised that I was tensing up ready to come and I told her to move her face away she but carried on rubbing my cock as I came. Thick cum exploded out of me and landed on me and Nadia's neck and top of her breasts. Nadia looked amazed and as I came off the high and I told her that many men prefer that to full pussy sex. I quickly wiped both of us up from the flannel by the bed and pulled her pussy up to my face. I started to give her intense licking and sucking and within a couple of minutes she was shaking from her first proper orgasm.
She tasted fantastic and I suggested a shower which she agreed to. We took our time enjoying washing each other and I made sure she washed all of my cock including the balls and she seemed pleased that my cock was getting hard again so easily. I washed her and she was shocked when she realised that I had slipped a finger inside her pussy and was teasing her clit at the same time. We stopped and dried ourselves before I led her to the bed again.
I got the lube out and showed her where to apply it and then passed her the condom which she rolled on. I knew I'd told Marie that girls should be on top to start with but I felt the urge to slide my straining cock into her welcoming pussy. I made sure she was well lubricated as I positioned myself between her legs I started to fuck her. She was tighter than her sister so I took it gently by slowly entering and withdrawing several times. Each time she took more and then she relaxed as she realised I had managed to give her my full length. I built up speed as she enjoyed it but before she got too close I withdrew and told her to turn over so she was kneeling. I spread her legs wider and holding her hips I guided my throbbing cock into her from behind. She gasped at this new feeling but soon started moving making it better for both of us.
"I'm going to come, "she shouted as I carried on pumping her, "ohh, yessss, fuck me."
As she came so did I, my cock deep inside her pouring my cum into the condom and holding her hips. She calmed down and I slowly withdrew making sure the contents were intact and I turned her over. I moved down and to her amazement licked her clean and she returned the favour. We decided that we'd best shower so Nadia went to her room and I used my shower. We appeared downstairs almost at the same time and she looked at me and smiled. Again time had sped by as it was only a few minutes before the others appeared. Nadia and Marie went upstairs too discuss the last day or so and I looked at Michelle.
"Thank you Bill, from what Marie told me I think they are both better prepared and they will now ask me for advice and questions. Hope you recover quickly because tomorrow I think we need to finish what we were doing on Friday when they caught us."
I nodded and could somehow feel my cock already twitching.
