I had a girlfriend who we discovered together could orgasm from just having her bottom fingered gently. We would keep a small jar of vaseline next to the bed and when she wanted it she would hand me the vaseline and I really enjoyed that because I love playing with girls bottoms. When she came I could feel her strong ass contractions on my finger.
She was interested in getting fucked in the ass, but unfortunately she had a really tight bottom and every time we tried it would hurt her too much.
What's funny is that although she had a tight butt she had a really flexible vagina, I have big hands but she really liked it when I would hand fuck her really hard with all 4 fingers plus my thumb. The first time I was working 4 fingers in her I was going slow to see how far I could go, but then she put her hand on my wrist. I thought she was going to pull my hand back out, but instead she pulled my hand into her deeper and then back and forth in a fucking motion. After that it was on for real, I'd fuck her so hard my hand would get cramped after a while.
This would really open her up for a day or two but then she would go back to normal. I liked putting my dick in her after she was relaxed and opened up, I could really feel how much I had spread her open. She would feel a little embarrassed about it because she could hardly feel my dick anymore but I told her I liked the way it felt and she was ok about it then.
Lots of fun from a long time ago, I wish I could do it all over again.
