Matt wasted the rest of the day until his sister got home from school

He'd jerked off twice, once using his {if mom-undies=true}mother's{else}sister's{endif} underwear, so the pressure to cum was somewhat diminished. Matt wasted some time on Facebook, wasted more time watching a videogame let's play, and got so bored he actually read an e-book one of his friends had sent him when his family had moved to The Hill.

Tomorrow, for sure, he was going to get up early and make it to school. Sitting at home doing nothing was way too boring. School would be boring, he was sure, but at least there would be girls to look at... look at and maybe, if he could get up the nerve, more.

Finally, he heard a key in the lock and giggling girl-chatter.

"You are in so much trouble." His sister, accompanied by her friend Amy, walked into his room without even knocking. Typical. Of course, if he got caught walking into her room, he'd be in big trouble. Talk about double-standards.

"Yeah. I missed the bus."

Amy gave him the look she might have given a leech sticking to her leg. "What kind of idiot misses the first day of school?" Amy was a tall girl with long gangly legs that seemed to go almost all the way to her neck. She had a decent figure and had featured in a few of Matt's masturbation fantasies, but her face looked like she'd been kicked by a donkey. Maybe she had because she loved horses... one of the bonds she had with Karen. She also owned horses which made her quite different from Karen... and himself.

"I didn't do it on purpose," he said. "Did you get the assignments? Please tell me there isn't homework for our first day of school."

"There's homework all right," Karen said. "And good luck getting a lab partner in bio. All the smart ones will be taken. The problem is, I didn't really get the trig at all. You were supposed to be there so you could help me."

Which was completely unfair. He'd failed trig back in L.A. Public Schools. An F doesn't normally qualify anyone to be a tutor. But that was what his mom expected.

He looked at his sister. If she hadn't been his sister, she might have been semi-hot. Blond, with a decent rack and an athletic body, she was popular with everyone, made friends instantly, and made Matt sick. Why couldn't he have a nerd for a sister so at least he'd have someone who understood what he was going through?

"I failed trig," he admitted, "but maybe I learned enough to help with the first day's homework."

"Great." Karen tossed him her backpack. "Assignments and textbooks are inside. Amy and I are going out riding. Tell you what. You do the homework for both of us and I won't tell mom you skipped school. Sound like a deal?"

"You wouldn't tell her anyway. You're not a squeal."

She shrugged, which made her tits wiggle intriguingly. "If you don't want the assignments, just give me back my backpack and you're on your own."

"Fine. I'll do the homework."

Amy looked down her nose at him. "I can't believe you missed the first day of school."

"You already said that, horseface." But he waited until Amy and Karen were out the door before he said it.
