Becoming Linda

I wished I could continue to give Steve a show, but my thighs had given up and I could not lift them any more. Steve sensed my dilemma. Being the gentlemen he is, he walked towards me, holding a towel in front of his crotch, and asked me if I needed help to do couple of more curls. His offer thrilled me and I could not resist.

He stood behind me and grabbed me by the ankles as I spread my legs as far as I could while still holding to the handles. I new this would give him a full view of my butt and the light blue silk underwear that squeezed between my ass cheeks. In order to give him a nice and long view, I told him as he held my ankles that I needed him to wait a minute as I was very tired and that he needed to be patient.

He was very glad to oblige. As I lied there on my stomach, I looked at the mirror, and saw that his bulge was now a huge tent and he was making no attempt to hide it. My cockett became so hard that it was very painful to push it against the hard bench. Once I got Steve's full attention, I started doing my curls while Steve was helping me lift my ankles. To reduce the pressure on my cocket I lifted my butt which I knew would give Steve an even better view.

After about five leg curls, my butt was going very high, and out of the blue, I felt Steve's hand on it pushing it firmly down. "It is better to keep it down in order to get the full benefit of the exercise" he said. I couldn't and didn't want to object, so all I could do was thank him. I felt his hand burning on my butt as it was holding it down and giving it a light squeeze. His thumb was pressing lightly against my asshole and with every leg curl, I could feel his thumb pressing deeper into my ass crack and against my asshole. The pressure was also building on my cockett and as I felt I was going to cum in my panties we were interrupted by Jim as he walked in on us and we both froze.

Jim did not say a word but it was obvious from my red face and Steve's attempt to cover his bulge that something was not right. Still he reacted like nothing was going on and just walked away. I was terrified that if he caught us, he would tell my mom and that she and John would give me the whipping of my life as they have done several times, especially John who always found reasons to spank me as he had me lay down on his lap.
