“Come lay here” Christine said playfully, “On your back.”I slid up on the bed and to my surprise, Christine spread my arms out and secured the... in straps that she had prepared. She kissed me full on the lips before I could say a word. Once my arms were secured, she leaned back and lifted my ankles, securing them over my head and to the headboard. This left my cock pointing up at me, my balls and ass totally exposed. Christine then got off the bed, removed her panties and returned with a bottle. There were six cars in the parking lot at the foot of the trail to the waterfall when we arrived. Before we set off I went over the three trails that we could take up to the falls. We headed along the blue trail, it was longer as it followed the valley around the mountain and the gradients were easier. The Black Trail was my usual route. I let Mom set the pace as we rode side by side. A couple of time we came across other riders and I pulled ahead slightly until we passed and then fell back to.

Without preamble I dropped to my knees in front of him and pulled down his sweat pants, freeing his ample cock. I ran my tongue along the underside and then wrapped my red bimbo lips around his shaft. His cock hardened in my mouth and soon my head was bobbing as my mouth stroked over his cock again and again. His hips began to piston as he stroked his cock into my mouth. He paused as a voice was heard just outside the dressing room door, however. ‘Derek? Are you in there, man?’ Derek looked.
