Considering it's a very simple application of graphics, the BJ animation is excellent - hands, mouth, eyes, hair, shoulder well done - it's for once even a decent knob, though it needs some veins for realism! - and the tipping back of her head once he has spurted is a great little detail :o)~
Plus, the little changes (shock) to her facial expression are neat. Nicely drawn breasts, and the widening, parting labia, during the first fuck.
I can't say I'm a fan of the "floating hotdog" of a penis penatrating her, though. I understand the dilemma - it's her and her cunt you want to watch, not his back and his pumping ass. But you'd just have to work the angle. A disembodied prick just looks like a magic carpet gone wrong :)
Also in need of work is the opening dialog. It really doesn't "hang together". "You've deserved it (=sex)" ... why? It needs better chat-up technique than this!
Lastly, it's a short game - nothing wrong with that, some are too long, bloody epics! - but it "cuts off" a bit too suddenly. He cums into her - curtain falls. She could at least smile, look relieved, look foxy, ask him to eat her out, say "We must do this again" - or else have a librarian come in and report them, if you're a spoilsport. Or get the librarian to join in, if you're a happy fantasist.
In any case, give these stories some sort of conclusion!!!!! Life doesn't end in ejaculation. Drama-wise, it should be a climax, not the catastrophe.
