You write Bobby well.

Finstock was really in character. And thank you for introducing me to this pairing.

I think this is the only thing I've ever seen/read with a version of Coach that I actually like.

You should make a part 2 it was realy good

This is interesting. You should consider doing a sequel.

That was TENSE. The whole situation was already tense and uncomfortable, but I was really sweating it when the dreadful realisation hit me that the one-time thing before Bobby could only be Peter. I like how you portrayed Finnstock as a loving and supportive man beneath funny weirdo that is Coach. (Also like the hint he overheard Scott and Stiles talking werewolf on the bench. Guys, learn to whisper!)
What I find most intriguing about this story that the supernatural involved is more of a detail. The everyday and yet incredible fact that your mother/girlfriend is unexpectedly pregnant by somebody terrible is the real drama and source of suspense. Pregnancy has become more terrifying than werewolves.
