This time I held it for as long as I could, keeping the dense smoke deep in my lungs to get the biggest rush possible. I could hear bells ringing in m... ears as I let out a little smoke and took in a short bite of air, so I could hold the rest in longer. My cock had grown to its full size now, a good 8" of rock hard flesh, and Erica's head was slowly bobbing up and down as she slid it to the back of her mouth, then back out so only the tip was enclosed, swirled it with her tongue, then slid it. I wasn't sure what he meant but he explained that he had a good friend who was a bit lonely and would really enjoy meeting me, he hadn't confirmed anything but wanted to check with me first. I thought about it and was a bit worried about it getting out if other people were involved but Tom reassured me Brian was very discreet and was a nice guy. It did sound like quite a sexy idea and said ok. Tom went out and phoned Brian, he came back a few minutes later and said he'd be round in about twenty. I was now holding her against the wall, penetrating her pussy as deep as I could. She started moaning incredibly, screams of pleasure were being yelled to the rooftops. I felt that I was about to cum, and I told her. She pushed me off and said not yet. My balls were aching, I had to cum. She told me to go sit on the bed and she would be right back. She left the room and when she returned, she was holding her smallest vibrator, one that she oftentimes kept in her bag for when she really needed. Calculating: She would be doing 65 mph, her speed when I passed her, they would be doing as fast as they could. I figured that I would catch them in a few to 10 minutes. My plan was to just bird dog her until I figured she was safely out of reach of the two scruffy riders. Fifteen minutes later I saw the three bikes in what looked like close proximity. A gentle rise blocked my view for about twenty seconds and when I crested that next ridge, there were no motorcycles where there should have.
