Not sure of the dynamics of this one, hopefully someone can explain this. My wife and I were having sex Saturday night when I decided to do something different about 15 minutes into it. Rather than nudgefuck her backstop or do the usual long strokes, I decided to change it up a little by teasing just inside of her entrance. I'd do short shallow strokes (about 2 to 3 inches in her) for a few minutes until her floaty trance-like feeling from her previous orgasm would go away and she was ready for me to go deeper. Rather than comply with her request, I'd keep on with the shallow strokes until she was on the verge of either begging or irritated. At this point, I'd shove myself deep in her and stop. Just stop all motion. Her first reaction would be an open mouthed OMG-That's too deep too wide too sudden look on her face immediately followed by a powerful orgasm. I did that for a few more orgasms until I got tired, then we switched to cowgirl. I noticed she did something similar. She would shove me all the way in her and grind her backstop hard. I don't mean feel-good kind of hard, it was causing her pain kind of hard. Rather than letting up at the point where it got too painful, she'd cum hard, sit motionless for a few seconds, recover and then proceed to dig in until it was painful again. After we were done, I asked her to describe *why* her orgasms were so much more powerful and her response was "Well, it just felt really good." I'm noticing more and more that her orgasms do get more powerful if she's on the verge of being overwhelmed. Anyone else who's experienced this care to clarify this for me? I've heard the term "pain slut" is this it?
