Several girls had been watching the boys' activities with interest and approached Susan. One of them, a girl named Jennifer who had tried out for the cheerleading team last year looked at Susan's feet pinned in the stocks and began ticking the soles of the poor girl's feet. Susan was very ticklish and soon she was squirming and laughing and crying as the girl tormented her.
One of the other girls had approached Susan's bare bottom and reached out and swatted it hard with her bare hand, making Susan jump. She applied several more swats to the cheerleader's exposed buttocks before both girls got bored and headed to class.
Brittany and Kylie came by and offered Susan some water and hung around for as long as they could to try to discourage any additional abuse. But they knew they would get in trouble if they were too late for class so they had to leave as well, leaving Susan to bake in the early morning sun.
Susan got her first blowjob taker an hour later when a senior classmate dropped $300 in the metal bucket and positioned himself in front of the naked restrained girl. This boy had one of the largest cocks Susan had ever seen and she was suddenly glad he didn't spend the extra $200 to have sex with her. As it was, he was so large she felt herself choking on his penis as he drove it deep into her mouth. She was very glad he didn't take long and was on his way.
One of Susan's ex-boyfriend's, Jacob, tried to negotiate a fee reduction for a quick fuck, but Susan had never liked him that much so she told him to pony up or get lost. He responded by following the lead of the previous boy and shooting his load on her face. Soon several boys decided that was fun and joined in and soon the girl's face was covered in white sticky residue.
Kylie came back with some water and used it to wash off the cum, but a few other students saw that and decided to apply some other liquids. One girl poured her diet soda over Susan's head, drenching her hair. Another poured some sort of juice drink down her back. The icy drink did help cool Susan off, although she didn't appreciate it running down into her exposed crack. A couple of other students saw this and added their drinks onto Susan's back as well, so now more liquid was dripping between her ass cheeks and into her pussy.
The tickling began again after lunch, not just to Susan's feet, but also to her exposed sides. To make things worse, another senior classmate decided to ante up the $500 and moved behind Susan and shoved his cock roughly inside her while three girls continued to assault her feet and sides with their fingers. Susan was struggling to breath as she was tickled mercilessly all the while the boy pounded away inside her. She felt him cum with some force and that was enough to drive her to orgasm as well, her body still writhing from the girls who continued to tickle her.
By the time the day was over, Susan had sucked four cocks and been penetrated twice, earning her $2200 for her day's work. She figured the videos would probably sell well, too and with just a few more days like this, she would have enough money to pay off her tuition debt and maybe even pay back her mom's debt and get out of this predicament.
