Going Batty Bonus
Another old TF sequence - a curious young man abuses an untested drug that claims to boost sex drive, causing a radical change in not only his sex drive, but the form and function of his entire body.
Human to hyper-endowed, anthropomorphic bat.
First several of these are technically clean, but the sequence as a whole is adult.
