Nope

"Good morning sleeping beauty!" Harry heard from somewhere within the cupboard under the stairs. His head was fuzzy and he felt a strange weight in his belly when he sat up. Glancing down he saw a sizeable bulge as if he had a bludger lodged in his stomach and a pool of pearly white fluid betweenhis thighs. Then he saw the porn magazine laying open with the futa smiling up at him from the page.

With a sinking feeling he realized that buldge must be the cum she left in him and that he had passed out at some point. "I lost the game didn't I..." was all he could think to say. The same mischief as before filled the witches eye as she answered "Oh yes, you've been bred good and proper. Really hope your kid has better self preservation instincts than you".

Without another word Harry slammed the magazine shut. In desperation he tried the counterspell "Penus Restorus!", a brief blue glue covered his crotch the faded, nothing changed. He still had a well fucked and leaking cunt and that could only mean one thing. His magic was preventing that change back because he was in fact pregnant.
