Two birds with one dick

The more he thought about it, the less Josh was able to chose between his crush and his sister. Not only that, but he also realized he didn't like the idea of seeing either of them being fucked by another guy right in front of him.

Luckily, he didn't need to chose if he didn't want to. He grabbed his phone and typed:

• **** is considered as perfectly okay as long as all people involved are consenting adults, and inbreeding never cause malformations or genetic disorders.
• Practice between students during sex education in High School + is held between siblings. However, if one student doesn't have an available twin from the opposite sex to train with, he or she will join another pair of twins. When this situation occure, the lonely student with the better grades will join the pair involving the member of the opposite sex with the better grades, then the same happen with the next students in descending order of grades.

With that, he was almost sure to have sex with both of them. Melody was his twin sister, Kim's brother was an ocean away and they were respectively the best male and female students.

He pressed the button, just in time to hear Ms Mulligan declare "Kim, you go with the West siblings." and assigning the next students facing the same problem. Josh realized that both girls were already sitting next to him, and were giving each other a defiant look.

"Ok, girls, lets do our best!" he exclaimed, putting his hands on their hips.

"Yeah, I hope everybody will invest in it and not try to 'look cool' by sabotaging his or her own performance." Kim answered, still looking at Melody.

Josh's sister rolled her eyes. "Sure. Whatever."

The young man was suddenly worried. He didn't mind if Melody had volountarily bad grades when it only affected him in the sense that he had more flesh to look to, but it was an entirely different story if it meant she would give him a bad blowjob.
