Monica's mind wandered as she climbed the stair-stepper. Her curly black hair was soaked with sweat and plastered to her face. At least this gym offered some way to relieve her tension. She had never enjoyed working out much before, but being on this prison-island they called a school had forced her to take drastic measures. She was so damn TENSE all the time!

The few cigarettes she had managed to smuggle into the school had been smoked during her first weekend of confinement. Now she had no nicotine, no dance clubs, and, worst of all - no dicks! God, how she needed a big cock - preferrably without a man attached to bother her!

Monica was stepping faster and faster, her prominent ass stretching her tight gym shorts. At home, she always had a way to deal with this kind of tension: either one of her stupid boyfriends or, even better, the extra-huge dildo her older syster had gotten her for her 16th birthday. Here, men were nowhere to be found. And even if she had her dildo, she had no privacy! Her room-mate was always home studying, and the bathrooms were shared with a whole floor; Monica knew she was very loud and obscene in the midst of a passionate moment, and the last thing she wanted was to be thought of as some kind of dirty slut before she had even been at school at week!

Monica's thighs were just plump enough to brush against each other slightly as she climbed the endless flights of stairs. Her brown Mexican complexion was accented by a sheen of sweat. She squeezed her thighs together and bit her lip. Her soft breasts hung heavy in her sports bra as she pushed herself to continue her workout. She resolved that she would get in shape, try to lose the padding around her middle and hips, and be ready to fuck any guy she wanted when she got back to civilization!

Pumping up and down on the stairmaster, Monica continued her daydreaming.
