I don't know, this gives me an icky vibe. It bothers me immensely that the teacher invited him into his house and wore his undergarments. I know it wasn't for sexual purposes, but even if you're showing the fact you're interested in girlier things, you should do it in a way that's appropriate to show (not being half-naked in front of your student). I'm not a fan of teacher-student relationships in general, so I couldn't read it fully through without getting uncomfortable.
