"...what's going on," is the first thing out of his mouth, when he sees the looks on his parents' faces. Maybe he should already know, but — he doesn't.
It's just like kissing before. Lev presses kisses all over his face and neck and ears and murmurs to Marlo that he loves him.
He takes off Marlo's shirt. That's okay, they did that before.
(He's kind of terrified.)
Alright — this is familiar, this is good, he's kissed Lev shirtless before — he puts his hands on Lev's hips, just barely touching the skin under his hemline —
"Uh. I really want to have sex with you but also I kind of want to throw up."
He's breathing really fast.
"What if I have gay sex and I like it and then I want to be gay forever and my parents. My parents aren't proud of me and they're going to kick me out--"
"I'll take care of you," he whispers, although he has no idea how. "Or you could not tell your parents?"
"Good," he says, very soft, and kisses Lev's forehead. "I love you. We'll figure something out, okay?"
