I know Alice doesn’t come across as reliable (tbf, neither does Ralph). But I think he did it, and here’s why. Put yourself in Ralph’s mind. Here he sees Alice casually banging all these people he knows. Ralph has it in his mind that he’s just as important as these other players. He’s says to himself “hey, I can do a that! If she fucked Baked, I can fuck’er tew!” So Ralph puts himself in her orbit.
Now, Ralph is not as experienced with ladies as he’d have us believe. This is not a man with many “one night stands” under his belt, unless you count whores, which I don’t. So, even though Alice should be easy (she’s a slut), Ralph doesn’t know how to close the deal, and it’s frustrating him. Keep in mind that, as disgusting as she is, Alice is one of the best looking non-prostitutes that’s ever talked to Ethan Ralph in a social setting. So how does Ralph proceed? He tried flexing his clout, that didn’t work. He tried buying her gifts, literally simping for her, that didn’t work either. So what can he do? Oh I know. He’ll get her drunk and hope she puts out, the old fashioned way.
Well, that didn’t go as planned either. Alice just did not want to fuck Ethan Ralph. In Ralph’s mind he’s thinking “Awww hell naw, this can’t happen to the Ralphamale. I got thousands in the bank!” He’s soooo close. He doesn’t wanna let her get away. So Ralph said “fuck it, no one’s gonna believe this bitch anyway,” so filled this semi-retarded transient girl with as much liquor as she could hold and he jacked off in her mouth when she passed out.
