Years ago while on a camping trip, my wife had me set on her lap facing her. She then started to lick suck and bite my nipples. This was really turning me on so I didn’t object when she started to play with my asshole.
When she realized that this was getting me even hotter she lubed her fingers (2) extremely well and started to fuck me with them. It only took about five minutes of this before I had the most intense orgasm of my life and without any stimulation to my cock. It was fantastic Duane
