I could clearly see the red thong string trapped between her cunt lips which were nice n thick and very exposed.My cock was damn near busting out of m... boardies so I reached in and began to rub myself while taking in this private show her sister was giving me.She then stood up after about 7-8 minutes of torchering me and slowly turned and announced she needed a shower.She saw my hand hiding in my boardies giggled then sped off to the shower.Fuck I needed to hurry and blow my load asap.So I went. Years later, it paid off. I could lock them into a female form, but itwas not the physically desirable kind that they were accustomed to.Instead, their new body was small, weak and physically plain. They had amuch reduced chance of causing others physical harm, and they would notbe able to use good looks to manipulate people. They still had a chanceat a decent life, but they would have to work hard at becoming betterpeople. It had been successful so far, but I had people keep an eye on. Also during these months, the four of played 3 more times, since that first night. Every time was fun and extremely sexual. And we, like Mandy and Jim, always ended the night, making love.But after the last one, we had a very open and frank conversation about the swinging. Jackie said that she really enjoyed doing this. It made her feel free, yet, she felt, it bonded us together even more than a monogamous relationship ever could. I told her too, that I really enjoyed it too. But most of all,. I pick up the riding crop and flick it in the air, testing the flexibility. You can’t hear the swish, which I regret, but you’ll soon know what it is. I walk back to the bed.The leather tip of the crop gently slaps the back of your thigh; each stroke quick, light and persistent. Slap, slap, slap, slap, six or seven strokes in quick succession. That has got your attention. I stop for what must seem to you like an age and then we I think you are least expecting it I bring the crop down hard.
