This is my first story so be gentle and enjoy. Would appreciate feedback!
_______________________
I was only one week away from graduating from college when I tore up my knee in a pick-up basketball game. I had to wait for two weeks for the swelling to go down before I could have surgery to repair it. My operating surgeon told me the rehab would take 18 months before I would be able to fully return to physical activity. I had been through rehab before, having had 3 previous knee operations, so this was old hat to me. What was going to be new this time was my physical trainer. Her name was Andrea.
She was beautiful. Andrea was 5'8" and weighed about 130 pounds. She had shoulder length brown hair and her face reminded me of Jessica Simpson. Her figure was well toned, as her job required it, and she had a very nice pair of tits. They weren't huge, probably a C cup, but I couldn't tell for sure as she usually wore a zip-up sweatshirt during our sessions. Her ass was amazing, and I consider myself an ass man. She, however, was very strict morally, and always wore plain white cotton underwear. They were quite big and not something I found sexually appealing. Despite her "granny panties" I still found her very sexy. I think it had a lot do with her looks, but she also was in a position of power over me, and worked me quite hard during my rehab sessions.
I always felt there was an unspoken sexual tension between the two of us. We flirted, but it was very mild and no one else seemed to pick up on it. I knew she was married, and trying to have a kid, but I knew I would have to fuck her before I finished up my rehab. With each session I became more and more aroused, and more committed to my goal. Not of getting my knee back to 100%, but to having my way with Andrea.
As I neared the end of my rehab, and my knee began to allow me more and freedom with what I was allowed to do, my rehab sessions became more and more intense. I was able to play basketball against Andrea. While she concentrated on how my knee looked and performed, I concentrated on rubbing against her during the games. I would let her back me down into the paint while I rubbed my crotch against her ass. I could have sworn I felt her rub back too. I would also find ways to rub and make contact with her beautiful breasts. There was no way she could have thought it was an accident after so many times, but she never said a word, she would just smile at me.
I had finally made it to the end of my rehab time, and my knee was working perfectly. All that was left to do was have my final re-evaluation, an insurance company requirement. I scheduled it for late in the day on a Friday, and purposefully not shown up on time. I was scheduled as Andrea's last patient, at 7:30 p.m. I called the office at 8:00 and explained I was running late, but asked if we could still take care of it that night. Andrea agreed but told me that she wasn't supposed to let anyone in the rehab center after hours. I had to keep myself from sounding excited over the phone, and was able to control myself. That would be the last time that night I would have that ability.
I showed up at about 8:15, and the reception desk was dark and there was only one light on in the back near the rehab center's separate workout room. I walked on back and Andrea was in the office for trainers filling out some of her paperwork. I thought about taking her right there, but decided to wait until she got me up on one of the trainer tables. I had not worn underwear under my mesh shorts, so I knew she would be unable to not see my semi-hard cock.
I was going to give her a chance to initiate, but if she didn't I was going to have my way with her, whether she liked it or not. Andrea turned around and saw me standing there.
"Hi." She said in her friendly tone.
"Sorry for being late, thanks for staying late to check me out." I responded.
"No problem, my husband is out of town so I have nothing to do at home anyways" She explained.
My mind instantly realized that I could keep her here and play all night without her damn husband knowing. This certainly was going to be a night to remember.
"Hop up on the trainer table, let's measure your leg muscles and check your range of motion" She said.
I lay on my back as she raised my left leg up toward the ceiling to check flexibility. I felt my semi-hard cock flop out of the right leg of my shorts. She saw it and gasped.
"Um, Craig?" Andrea softly said.
She looked a bit uncomfortable, but didn't stop looking at it. I played dumb, until she pointed it out to me.
"Sorry, it's laundry day. I don't have any clean underwear." I apologized.
I knew what she was thinking, but also knew she wouldn't act on it. I was going to have to get aggressive.
After she had checked my flexibility, it was time to head into the fitness center room that was only for rehab patients. On the walls surrounding the room were various pieces of exercise equipment. The floor was carpeted so that would be easier on our naked bodies I thought. I followed behind her, as I always did, and began rubbing my cock through my shorts.
As soon as she hit the light switch I made my move. I came up behind her quickly and grabbed her with one arm around the waist, the other grabbed one of her luscious tits, and I pressed my growing cock up against her ass. She jumped and shrieked as I grabbed her.
