So, having seen some of texengnr's posts on bondage and stuff, I talked to the SO about it and we decided to give it a try. I had the rope and the scissors to cut it if needed, she got naked on the bed and I started to tie her arms behind her back. I got a decent knot tied when she said, "oh, no" and a bad rotten egg type smell started to fill the room. She jumped off the bed the best she could and we aired out the room for a bit to try again.
I put her on her back with her face hanging off the edge of the bed and placed myself in her mouth. I had forgotten about the unfortunate flatulence and was rather aroused until I heard a whoopee cushion type sound and the air was filled with an unpleasant odor.
Loads of laughter and an immediate loss of erection ensued, and I was not getting any that night. So, while we created quite a lasting memory, it was not the type of memory I had hoped for.
That, boys and girls is why sometimes it is better to play with a pro!
