She was fully into my game by then, shaking her head from side to side, pressing her ass into my probing digits, and thrashing as she discovered a new... way to come.At her pinnacle, I pressed both fingers as far as they would go, twisted them a little, and then gently withdrew while she was completely distracted by her orgasm. When she recovered, my fingers were out of her rectum, and there was no pain to associate with entry, or exit.After a brief respite, and a trip to the bathroom for Tammy,. I realize that wearing a thong was not the best method of holding for my dildo considering I’m wearing a skirt. I had to readjust it about 4 times and squeeze harder to keep it inside. I tried my best to make it unnoticeable as I reached in my skirt to push the dildo further in my pussy. This was a very pleasurable and frustrating part of the experiment.Observation 4: When I got to class, I was a dripping mess. My juices were flowing down my leg and I was so horny. Every step I took, I could. There was nothing subtle about my sister and it was fast becoming apparent I was living with two nymphomaniacs one in her prime and the other in training, life couldn’t be better and finally Flo broke off taking a step back, “Ooops got a bit carried away there eh” she said with a giggle but it didn’t seem to matter. Flo wandered around putting things away and I couldn’t help but notice how tight her jeans were clinging to every curve and enhancing her thigh gap, I hadn’t really looked at her in. She smiled; whispering again in my ear that my pussy was very sweet. I could feel my own juices running down my thighs. I moved to get out of the car at my station; but the woman grabbed my waist from behind and made me stay there quiet. She whispered that she had even more thing to show me at her place.So we got down after another three stations and walked just few blocks to her apartment.As soon as we got there, she offered me a glass of red wine.Then she started undressing me. I felt totally.
