The weekend came and I prepared by shaving all of my hair from my genital & anal areas, cleaning out with an enema, and stretching out with a butt plug. I then drove out to Mark & Shauna's house.
I arrived to find Shauna waiting for me at the door. She was dressed in a pool robe and, as soon as we were inside the house she closed the door and asked me to lean against it. I placed my back to the door, my eyes already riveted to her body that was now being exposed as she let the robe fall to the floor. My eyes dropped to her pelvis as I realized that she was already strapped and ready to go. I could feel my penis throbbing with desire as I looked upon her. I managed to ask, weakly, when Mark would be joining us. Shauna told me that Mark bailed at the last minute, not wanting to watch her fuck me. I asked if they were ok with us proceeding to which she answered by walking over to me, placing her hand behind my neck and pulling my mouth to her breast while her other hand began undoing my pants. I helped her to remove my pants, soon followed by the rest of my clothes. Once we were both naked we hugged each other close and I felt the press of her breasts against my belly and the coolness of her strap-on against my legs.
