I kept going and Jess did as well. Suzy tried to tell us something but it got lost in her sister stomach. I felt the slickness spread down to my legs ...nd then on to Jess's face and forehead. Suzy had been shaking for over 3 minutes before she screamed and pushed onto the bed. She was rocking back and forth on her sister's belly and pushing her pussy into her sisters face. She sat up and was forced kneel to stay in her. She kept her pussy glued to Jess. She took her hands and put them on Jess's. I had always liked Jen, so I wanted to change her too and managed to tie her up. Sally showed up late though and just came in the house as she usually did. I told my sister to act normally with her, but Jen was making a lot of noise, I didn't have anything to quiet her down with, so I just turned it off. She stopped making noise, but when I took the mask off, she was out of it. I cleaned up all my equipment and hid it away, but she wasn't getting better. Eventually my sister and Sally came in. It did not look like circulation was cut off this time but still she could not move."This machine is going to fuck you and I'm going to spank your breasts with a riding crop. This will happen until you cum, do you understand?" He asked her.A puzzled expression spread across her face but she nodded. The box was connected to a small control console next to it. The wheeled cart it rested on also held a small battery powered device and some large needles. He reached down and took the battery device. Amara playfully replied, “From the twitch I just felt in my hand; he likes the idea of the twins prancing around the house. We might even find a few items for Eira.”We played around for a little, but with my now sober mother upstairs, we restricted ourselves to kissing and some heavy petting. I gave Laura an extra-long kiss, along with a cheeky grope of her ass as she left us to sleep in Lauren’s room. We had to keep up appearances, after all.Once Amara and I were in bed, lying in each other’s.
