We get it bro, you don't like incest.
But it really ain't that deep, you're reading far too into it, people vote, he makes whatever vote wins. MW was more story focused and that played into the sex scenes, it wouldn't have made sense if her son just straight up jackhammered her from the beginning, It played it out the way it did because it complimented the story and the how the characters were feeling.
Same goes for Jenny and the Bully, of course that's going to be a bit harder and intense, he's a Bully, the whole short wouldn't make sense if the Bully acted like the son from Southern Hospitality.
Speaking of which, that kid is timid, and clearly doesn't have the confidence to fuck properly or proudly considering he's fucking his sweet caring mother in the back of the car, again, it goes with the story and compliments the characters and their development.
I shouldn't have to say much on the Beastiality side of things, you've ever watched Horse's on a farm going at it? It ain't slow and sensual, it's quick, deep, hard, rough and over in less than a minute.
Storytelling is a thing in films and movies, and characters act a certain way either by design, or to make room for character development later on the story.
Bad example here: If Goku started his first Super Saiyan form at Super Saiyan God Super Saiyan When DBZ first started, It wouldn't leave much to the story and character development as a whole would pretty much fall flat and any set up for growth wouldn't really exist and there isn't much left for him to grow.
