If a girl invited you over to her house?

What would you think?

BACKGROUND INFO…
I asked him to prom and he said yes.
We text quite a bit on and off (alot more now then usual!) but he has only texted me first a handful of times. We also "snapchat" a bit (iphone app)
I don't see him alot in school but when i do he smiles at me or says hello.
He is really shy and i'm even more shy so its hard to tell.

We've gotten to know each other good over text but i want to know him more. I'm starting to fall for him. I told him we should hang out sometime and he's like "yeah for sure lets do it Allyson" and I said "ok whenever your free. " and he told me a day but I was busy so he's like "okay some other time that week for sure" so I said "my house or yours" and he put "ill go there!" and said "lets do it for sure"

I want to make a move like put my head on his shoulder or snuggle up to him maybe even kiss him but i don't know how? Will it ruin our friendship if i do? What if he doesn't like me like that?
Honestly i want to get it on with him lol but my parents will be home.so.

You are suffering from a sexual illusion and have reached into fictional levels of human behavior. What you describe is not to happen. Shy is the operative word? You say you are "even more shy?" What you describe as a seduction scene IS NOT BEING SHY specially since there's absolutely nothing going here. How old are you? This is pure fantasy. Another term is "booty call." You have a sexual desire to be with a guy you hardly know?
