Pokemon Breeding

By the time she realised that she pushed her master a bit too much, she's already on the bed, legs spread, and his human penis ready to penetrate her Pokémon pussy.

To have a male member inside her is an exotic thing, and seeing her master's erection ready to plunge deep inside her, she can't help but welcome it, to have a human male's sperm flooding her uterus, evolved to form and lay eggs, where nothing else has ever been there.
