The animation looks good, though the female character is the only one that appears to be a giant headed, freaky, wide eyed anime character while the others look human. Other people have pointed out the low sound volume and the strange eyeliner mishap on her face.
When the troops are spitroasting her, her hair seems to be phasing through her neck. When they are DPing her, it looks like a plastic surgeon scared up her butt with his initials, or some wire frame of her body is poking through her flesh. Creepy!
Also, her butt hole seems to be nothing at all and the guy behind her looks like his genitals are just passing through her flesh and into her model, while the other guy SEEMS like he's having a go at her vagina, but at the end of every thrust his cock molecules pass right through her pussy molecules, causing... I assume... Hot Fuck'n, which is like Cold Fusion, only sex based.
The pill acts way to quickly. The second it touches her tongue she's instantly a slave to her base sexual needs. You could easily drag out the struggle against the rising desire in her into a cartoon on its own and I'd watch that... With my webcam politely covered in tape.
Anyway, other than those few nit picks, s'good!
