Cathy suffered in high school because she was heavier than what fashion demanded. She was pretty enough, with bright eyes under dark eyebrows, a pert nose, and a welcoming smile. She wasn't obese, in fact not even technically overweight; but she was thick enough to get teased. Some boys called her "the well fed one" -- not to her face, but it got back to her from other girls in her class. That made her even more shy than she was already, so her personality did not overcome her low social standing. It wasn't her boobs that kept her from having a boyfriend -- they might be a little small for her proportions, but they were generous enough to have thrilled any boy who might have had the courage to take her out and get his hands on them.
There were a couple of boys who went beyond the usual teasing. Cathy thought they must be somewhat attracted to her, otherwise they would just have ignored her. But one was in a class behind hers, and the other was not confident in his own social standing, and was afraid of ridicule if the other boys in his class thought he was going out with her.
There was nothing wrong with Cathy's hormones, however. She had discovered the delights that her pussy could give her at a very young age, and she fingered herself to orgasm every night, and sometimes rubbed herself for a while in the morning, or when she got home after school. This habit was what led to her undoing.
Gina's social standing was a completely different story. Outgoing and talkative, she was a popular girl, active in several clubs, and friends with most of her classmates. She too had a problem, however. She had known for a long time that she was interested in girls, and only in girls. If her classmates had realized this, she would not have been so popular in her school, so she made sure they had no clue about her orientation. She was an attractive girl, and had been invited out by many boys. She gave excuses for turning them down when she could, but had accepted a few dates when it would have been too awkward to have declined. She never allowed more than a good night peck on the cheek, however, and acquired a reputation as an ice queen when it came to dates. Eventually, the boys stopped asking her out. Someone speculated that she must have a boyfriend from another school. This idea was repeated enough times that it became the common understanding. Gina never lied about her relationships, but she did nothing to discourage the rumor when it got back to her.
Popular as she was, Gina was invited to a fair number of sleepovers. These were a pleasant torture for Gina. It was a total turn on for her to see the other girls in nothing but pajamas. Some had furry slippers, but at the beginning and end of the school year girls would often be in bare feet, and this bit of nakedness excited Gina. Sometimes, even, some of the girls would wear only boxer shorts on their lower halves, and Gina would get moist looking at their bare legs. The downside, though, was that she had to pretend to be interested in boys, and she had to restrain herself from touching any of the luscious fruit that was dangled before her eyes.
If there was one particular girl that Gina had the hots for, it was Cathy. Where others saw too much, Gina saw a soft girl with lovely skin that she yearned to caress. Those plump thighs would be wonderful to straddle, Gina thought, and she often masturbated to the thought of Cathy and her rubbing their pussies on each other. She had seen Cathy's tits in the locker room after gym class, and could not get over how firmly they stuck out, and how perfectly smooth the little areolas around her nipples were. Where others saw too big a butt, Gina fantasized about sitting on it while she gave Cathy a backrub, and rubbing herself without Cathy being any the wiser.
At the end of their senior year, the class decided to have an outing that would involve camping overnight. Some families were willing to pony up for renting some tents for the students to use, but the call went out for students whose families had tents to sign up and bring their own. Gina's family had a two-person tent, and Gina saw an opportunity. She didn't have any definite idea about how to get into touching Cathy, but she thought that spending a night in the same tent with her would be wonderful. Of course, she couldn't go ask Cathy to be her tent mate right away -- that would have been too obvious. But Gina was a clever girl. She got very busy with her extracurricular activities, and didn't get around to signing up for providing a tent until most of the class had made their arrangements. She waited until Cathy and a few other of the less popular girls were the only ones left without arrangements, and only then told Cathy that her family had a tent, and Cathy could share it with her if she wanted to. Cathy was flattered by this invitation, and immediately accepted.
Together in the tent, the girls took off their day clothes and got into their pjs. Gina got a few glimpses of Cathy's bare skin, which was exciting, but both were very soon covered again. Light was low, but there was some. The organizers had set up a lantern that would last all night, and enable the students to get to a latrine without running into anything, and the tent fabric was thin enough to let some of that light through. The girls whispered for a while about this and that, but the chaperones called out that it was late, and the camp quieted down.
