a question of ethics?

[BobboFitos]

heres the situation. my mom is a high school teacher close to where i go to college, and has some students who are now seniors. (Who she's had for several years now) for some reason, im not sure why, she told these close students of hers that (since i now live in apartment off campus) i would love to prepare dinner for them some time.

this isn't really true, as i am not a good cook, but both girls are pretty hot and 18. so. this leads me...

is it wrong to invite two high school girls over for dinner, and blatantly hit on them etc etc ? the reason i think it is, is that they're my mothers favorite students or something like that and probably just want to see my apartment. (its pretty cool)

im probably missing some details, but just want to hear general thoughts. (I'm 20, as well, so it's not like im a creepy grad student who needs to score with high school girls..)
