Call me naive, but I never knew there was a name for this move, Stripper Slide or P2P!! Are we talking about it being while the guy is covered or uncovered??? It has only happened to me 2 times, both uncovered, and honestly the ladies took my by surprise and it freaked me out because I didn't know what was their intention with this move. LOL.
I remember the first time, we had just finished round 1, she took off the cover, cleaned me up, but I was still hard, so she climbed back on top of me and started to "slide" while I was uncovered. It was the first time meeting this particular provider so I thought she wanted to go for BBFS, so I said "Whoa...wait, be careful there!!" and gently eased her away. We both laughed, and then I realized later she probably just wanted to slide, but I was still very cautious since BBFS not for me even if it is offered.
The other time it was with a provider I had known already a few times, so we were more comfortable. Have to admit I needed some help that day to get going, so she tried a few things to get me hard and eventually was sitting on top of me and began to slide on my dick uncovered. It was an amazing feeling, like someone mentioned above, having a warm wet pussy slide against my cock. She didn't warn me about doing this before she started, so again it took me by surprise. As I got harder and harder, she kept going, sliding on me uncovered and closer and closer to the tip of my cock. Although it felt really good, I was a little concerned about her wanting to go BBFS. And believe me it was hard to resist too since I was uncovered. I eventually had to ease her back. It was too tempting for me!!! LoL.
I have not done it covered, tho I guess it may be more enjoyable that way since no worry of getting too close!
