I feel weirded out by the thought of using a vibrators also. We discovered our flatmate's stash and decided to have a lightsaber battle. When she came back she told us she used it on her mates ass. I was mortified.
This. I'm not doing it. I don't mess with her butt unless she wants it and I expect the same.
I had a girl who wanted to be choked and I wasn't on board with it back then, being new at sexing and all. Probably do it now, though.
One girl wanted to call me daddy. Not just sexy daddy, I think she had issues. We had a bit of a bad break up, then got back together last Valentine's day. She bit me on the shoulder and tore at my back. I was okay with the biting, but the scratching just hurt like fuck.
Another girl let me braid her long hair and use it like a bridle. Turns out I suck at braiding hair and she taught me how after it fell apart. I also learned that if you pull a woman's hair, you start close to the scalp, not just yank the end.
Another girl let me use her boobs like mountains to play with action figures after we watched an episode of Family Guy and I said, "Hey, I have Hotwheels."
The first girl I ever fingered clipped my fingernails the next day. Turns out that's a big deal to some girls.
I feel like my stories are tame next to some of yours. And, Rob, never stop being you, man. Keep making boobie and dick threads.
