As for dressing and undressing, she had to be helped, and of course Elizabeth was not to expect her to talk. At best, she could only hope that Anna wo...uld once in a while obey a command that was repeatedly given to her.The nurse was not yet finish giving instructions when the train whistled three times then slowly began to move on the track. As soon as the nurse was back on the train, she bade farewell to Anna with her hand - getting no respond from her - and she was soon out of sight leaving. I wanted to get naked with her as quick as I could, but I paused and looked at my wife. And she nodded yes. So I slowly lowered my shorts and exposed my dick then the balls. She looked for a few seconds then I felt her hands on my balls. She was lightly rubbing then saying how smooth. This got me hard, they each made a comment about my erection. Her friend said I couldn't believe how smooth my balls felt. I said they feel even smoother on the tongue. She looked at my wife for the ok and then. But once more I got greedy. The clock on the nightstand said two-thirty, that one torrent was oozing out her cunt, trailing downward, watery, pale, and bubbly. My softening dick stopped, it began to rise from the dead, and temptation was too vast. Sliding into her again I thought I was fucking a jar of mayonnaise except it was a very small jar that was still tight around my dick. Hooked I didn’t even contemplate about pulling out, instead my sister cunt overflowed with my cum. Looking back I. After a couple of days, they texted me that it was fine to have a threesome to fuck her only.They invited me to their place that weekend. I was a little busy, so I told them that I will not be able to visit them next weekend. In the meantime, we were texting what they wanted to try when I was with them.As we had not shared our pics, we thought of having a video call on a Tuesday night. We had a nice naughty conversation, and they were very excited for their first MMF encounter.It was a Saturday.
