It was a while ago, but one of my most thrilling encounters was with a girl I knew who had a friend. The friend was a highly sexed woman in early twenties. She had asked my friend if she knew any guys that would join her with another girl. My friend was bisexual and suggested the three of us get together in a hotel in Brighton.
It was a cheap and run down place, which actually added to the thrill. It was obvious what we were there for, but I suspect many used the place for secret rendezvous, so the staff didn't question anything. The girls insisted that they perform for me first, which I was more than happy about. They vanished into the bathroom and changed into some skimpy undies, then returned waving naught dildos and giggling like mischievously.
I was told not to move from the chair until beckoned. The naughty sleazy girls kept me waiting a long time while they romped on their bed and found intimate places for their plastic toys. In the end, I couldn't stay still ...
Perhaps next time, I will go into more detail, if you'd like to hear about it.
