That guy is dangerous and he shouldn't be around either one of you. It's not normal behaviour for a guy to talk to his girlfriend's child (whatever the age) about masturbation, or to show them porn, or to start inappropriately touching himself in front of you. Why did he wait until your mother was out cold before doing this? Because he knew she'd tear him a new one if he tried it in front of her.
There's a name for the sort of stuff he was doing to you: grooming. He's trying to coax you into having sex with him. He knows that if he can ease you into agreeing to it by gradually increasing the pressure, then if you complain about it later (or tell your mother) he can argue that you agreed to it and everything was consensual. And if the porn he forced you to watch involved a trans woman, it's possible that he's fetishising your own transness (otherwise why would he make you watch that specific type of porn?) and that he's got it in his head that he wants to carry out his fantasies on you.

He keeps coming by saying "Sleep with me tonight"
Why on Earth would he say that, when his girlfriend is already there? There's only one reason: he wants to sexually assault you. You are in danger, and sadly, you did stay with him for quite some time while he did these things... so that's going to make him think you accepted what he was doing. I know as well as you do that this is absolutely not true, and that you probably felt intimidated or cornered and were worried about what would happen if you fought back, but in his mind he thinks that this means you were okay with what he was doing. And that means he's going to keep trying unless you take decisive action, because he believes it's only a matter of time before he gets what he wants.
You have to tell your mother, and depending on your age you could get the cops involved. It doesn't sound like he's done anything (yet) that would necessitate police action if you are an adult, but if you're under the age of consent then the cops need to be called right away.
Unfortunately, there's a chance your mother won't believe you at first, especially if she's already angry at you (I presume that's what you mean by 'pissed'? 'Angry' rather than 'drunk'? You did say you can't wake her up). If you've argued about something to do with the boyfriend, she might think you're making up stories to try to split them up. There's no easy solution to this I'm afraid, so you just have to be as honest as possible and give her as much detail as you can. The cops can also help with this, especially if your mother reacts badly.
So as soon as she wakes up in the morning, take her to one side and tell her everything. Tell her how it made you feel, and tell her you're worried that the dirty old perv is going to try something with you. As you are currently at his house, you both need to leave first thing in the morning. Pack your bags, and get out of there. Tell her that even if she doesn't want to leave, you're leaving today.
You should not be under the same roof as that man for another second.
