Aaaah, giant images. :p
The more information you can give me, the better. What I'm really looking for is, at least for the males, not necessarily the shy type that would run away from a girl that throws herself at him... but rather the type that can't get
the girl. I say that because think I've figured out the teacher. She's not as strong as the previous concept, she's even a little submissive. I imagine it isn't so much that she's seducing innocent nerdy boys, but so much as letting
them have free reign with their sexuality... and her.
What I mean is, she's not throwing her hands down anyone's pants anytime soon- she's more likely to just present an opportunity for an otherwise sexually deprived boy to... well, release all that pent up sexual energy. So I think she's even a tiny bit submissive. Or rather, she's assertive and maybe even domineering outside of sex, but her aim is to dominate her otherwise shy and innocent male partners into just taking what they want.
Let me try to explain. She doesn't get off on a stud in the dance club rubbing up against her. She doesn't get off on, say, making an innocent student orgasm against his will. What she does
get off on is taking that innocent student, and then teasing and encouraging him to the point where he takes what he wants like an animal in the wild. Sexually, I imagine she likes to be plowed into. Mentally, she likes the shy and innocent boys.
In short? Character development is her turn-on.
Now, as for girls, she probably will take a more assertive stance. I think she is
bi, but leans more towards men. Therefore she'll interact with the girls in a way that is more of a mentorship than the outright sexual relationship she'll have with many of the boys. She'll more or less groom them as her successors, and then throw them in the direction of a boy they want to seduce. She might like to watch, she might even participate. She won't be above popping a cherry or two with her fingers or toys... or otherwise getting the girl nice and acclimatized to sex.
She's immature, probably just as immature as some of her students. Doesn't always act too teacherly, can't really be strict, I imagine she was a pushover for a good portion of her life, and probably still is. This position of authority is probably the first time she's had the upper hand on someone, and a particularly assertive student could probably treat her pretty badly if he got the courage to. She might even be turned on by it; rough sex, choking, humiliation, ect.
So, to reiterate- what am I looking for in the boys? The guy who might be shy and nervous asking his crush out on a date... but would definitely know
what to do with a naked girl if she was in front of him. He's the kind that might masturbate a little bit too much, and is unafraid of sex... he just can't get any. So lots of repressed sexuality just waiting for the chance to come out... no pun intended.
The teacher might even be submissive... this whole sexy affair might not even be her
idea. So, in a way, it could be the student seducing her.
Not in the usual way, by being bold and aggressive and sexy- but rather by being shy and nervous but very curious and willing.
It could start as innocuous as a student asking her about relationships or her own personal life. She concedes being displeased with her sex life, might even complain to the student- which leads to some lightbulbs clicking. Or she notices that a particular student has a hardon every single day
in her class. At first she confronts the student after class in a purely professional (albiet misguided) manner, pointing out that such 'feelings' can be a distraction and inquiring as to how to solve the problem. They get to talking... lightbulbs click.
