The boyfriend was amazed when I tried something new not long ago. He was fucking me and I had him hold still for a bit, went semi-soft myself, then moved my balls to the side and pointed my dick down to my hole and used his dick to help guide my dick into my own ass. I only got just past the dickhead but it felt amazing for both of us especially when I came first and he got to fuck me bareback with my cum up my ass. It was extra intense for me with the double pen, then as he resumed thrusting, his dick rubbing against mine.
I was curious though, do any other bottoms out there do this? I love it but it's difficult to do. I get too hard to penetrate myself most of the time.
