It was a tale as old as time. Two childhood friends grow apart over the years, but fate brings them back together. Brandi had known Kate since they were kids but only through high school. She had drawn the short stick in the puberty lottery and Kate became the queen slut of the school. Brandi could stand to lose about thirty pounds and still had some acne, but was doing much better than she had been before she cut out soda. She had ample assets of course, they were so big that jogging became a dangerous pastime, so she had been swimming instead.
Both were in college now, but Kate was failing out of math. She'd asked Brandi for help and Brandi, being an idiot, agreed. When she answered the door she found that Kate was still stunningly beautiful. She had the archetypal hourglass figure and wore short shorts and a tube top. Brandi could have held all the clothes Kate was wearing in one fist. It would have been hard to see two greater opposites. Kate was smiling dumbly and gave Brandi a hug, "It's so nice to see you again!"
Brandi rolled her eyes when Kate wasn't looking, then smiled back once they faced each other. "Long time no see. It's been ages."
"Thank you so much for seeing me." Kate seemed exasperated. "I knew I could count on you." Brandi let her in and led her to her room. They sat on the floor and spread out. Kate showed Brandi the chapter they were on.
"Ah," Brandi nodded. "Trigonometry. I'm afraid you will just have to memorize a lot of it."
"Yea." Kate pouted. "I keep trying to make it fun by studying with other people but I just wind up getting distracted anyways."
"What makes you think I'll be any different?"
"Well, you're my friend, and a girl." Kate explained. "The way I usually keep getting distracted is... well, you know how I am with boys." Brandi chuckled with Kate on that. At least she was self-aware. "Alright, so..."
Kate explained what she knew and didn't know. Brandi's could feel her envy choking her. None of Brandi's study sessions had come to sex before. She took a deep breath to get back on focus. "Here," She rolled to her stomach beside Kate and pointed. Kate inched in closely like they did when they were kids reading magazines. Brandi had almost forgotten what it felt like. Brandi explained the unit circle and conversion thereof before looking up and seeing Kate staring into her eyes.
"Oh! Sorry!" Kate smiled awkwardly, "I'm already zoning out. You're so smart!" They way she blushed and looked away was not something she had done with Brandi before. She shrugged off the strange feeling and continued.
"Here you will see the Cosine is equal to the-AGHHH!" Brandi felt her body tense as Kate poked her ribs. "Kate!" Brandi tried not to laugh.
"You're more ticklish than I remember." She chuckled. "And pretty."
"Kate," Brandi smiled at her, "You came here for a reason remember?"
"Right." Kate slapped herself in a joking manner and put on a harder face. "Let's go!"
"Good. So, what is the answer to this question?" Brandi pointed.
"Uh." Kate put a finger on her lower lip in thought. "It's the Tangent right? That's the third one?"
"You haven't been paying any attention have you?"
