We had a bit of small talk, but mostly it was about, what we were going to do that weekend, apart from what we had planned in the tents, we wanted to ...xplore, there was a cave that my friends had discovered that I wanted to visit, and she wanted to walk along the nearby river, and go for a swim.We knew it would be dark soon, and we headed back to camp, she was a bit scared of the dark, and so she held onto my hand tightly, eventually we made it back to the camp, we both got changed, even after. I didn't think it would be Isabel, she never knocks, but it was. Peep had walked her over and she didn't want him to know she had keys to my apartment. I looked out and saw his cute little butt swaying down the hallway as I stepped aside to let her enter. "Later, Peep," I called to him. No response.When I turned to reenter the apartment, Isabel threw her arms out, plunged herself into me, embraced me with a giggle, and nearly knocked me on the floor. Evidently they had spent time at the bar. She lubricated dilator 6 and I watched on the screen as she began to insert it. Number 6 was now removed and she picked up the flexible scope. I watched the whirl of activity on the monitor screen and now I saw my buttocks from a different angle. I felt my bottom being parted, but this time I could see my anus in the center of the monitor screen. It looked a bit like a shiny target that was getting bigger and bigger as the device got closer to my body. Contact. I felt the cold end pushing. I gasped too. That feeling of my body being invaded by something that big, of being impaled on a cock that felt like a fence post, was something I would never get used to. My eyelids fluttered and my pussy started a reflexive contraction. I had to wait until I could get calmed down before I could take any more.Jolene tried to help out by licking the junction of Bud's cock and my pussy. That made me hotter, but it didn't actually improve the situation. I certainly wasn't going to tell her to.
