Trying to remember the title of a short (horror?) film that I saw once?

It s about a guy (likely teenager) who finds a weird-looking hole in his bedroom wall. Being the oversexed teen that he is, he decides to put his dick in it and the end of the short reveals that the damn thing is pregnant somehow and I believe it even ends up giving birth to some monster creature. I think it might even have gone so far as to have him try to raise the creature and his mom finds out and ends up killing the thing, which angers the being in the wall and that s where my memory of this short ends.

I need peace of mind because I m now not even sure if I just had a really messed up dream or if this was actually a short film I saw once.
