HUNTB-095 "I'll study hard, so I want you to teach me naughty things..." A serious female student asked her tutor (me) for a lewd favor! Now I have to teach both studying and naughty things...

The female student I (a tutor) teach is serious and cute, but she's more interested in dirty things than schoolwork! I've been trying to avoid it, but one day she said, 'I'll study hard if you teach me dirty things...' Every time she solves a problem, she asks for dirty things. Thinking that if her guardians find out it would be bad, but losing my reason, I couldn't hold back and inserted my dick! Repeatedly fucking her while teaching her studies and dirty things, ejaculating inside her over and over...
