That kind of "progess" thinking is what makes it crazy. People don't follow a strict path of flirting, kissing, touching, HJ, BJ, fucking.
It's a story so, sure, do that a bit but acting like Sam should have had some invisible barrier keeping him from, I dunno, touching her pussy. Or Putting his mouth on her pussy, Pulling his dick out, etc is what's illogical.
A genuine question and not at all an insulting accusation: have you ever fucked? Met someone of the sex you're attracted to, got to know them and had sex with them? I'll assume you're a dude attracted to women from here but swap out your preferences if not:
Yes or no, I don't care if you've fucked beyond making a point. If no, sorry. If yes, think about how that went.
Could you imagine having that person in your bedroom, nude, tits in your mouth, her panties on your floor, etc...and not trying to fuck or get head...because you two had only kissed a few times before that moment LOL.
Consider how insane that would be.
"Well, Suzy, my balls are blue and swollen and I've been in love with you for a decade...BUT...we have only kissed a few times before today so despite you being naked and on my bed I'm NOT gonna try to fuck....or get/give head"
No, lol. That's not how humans behave. That's alien shit. That's bad writing.
