Biology class would fall under The Science teacher's instruction. I am sure Miss Chang could explain some interesting bits of biology, covering topics such as: how to shrink your enemies, how to reverse or halt the outward signs of aging, and how to create a bacteria that will consume plastic from the ocean. (as well as ladies swimwear)AltosandHerdone ... there's a chance on a biology class ..lessons ?
What we really need is a sex-ed class taught by everyone's favorite extracurricular activities leader... Trixie. I mean, she is great as a dance teacher, but she has a lot of free time, and Sex Ed and Health courses are frequently handled by gym teachers, but Sally is busy being on the school board.
Seriously, imagine Trixie teaching sex ed...
"Hey there MC, I was thinking I should really show these girls how to keep from getting pregnant, by way of making sure they can give amazing head, so they can make all the guys blow their loads before they can pressure the girls into sex. A guy who just came from an amazing BJ is hardly going to need to knock up one of our teens. I am thinking that I will need about 1000 bucks worth of practice dildos for each girl to get her own, and I may need your opinion (also your penis) when the time comes for a practical test. How many times can you go in a row, anyways? I guess we'll find out. Ooo, I could also prepare lesson plans for anal, can we order lube by the liter?"
