She thinks you're too Innocent

"It's like you've never touched a girl before. C'mere, I won't bite."

According to Sam, you looked like a deer in the headlights while talking to a girl at the house party last night. Hey, she's not judging, but it was hard to watch, and she'd rather help you out than watch you flounder again.

Like most things, Sam's pretty casual about intimate things, so she thinks the best way to give you some confidence is to help you get used to touching girls. Specifically her. C'mon she's just helping you out! (Though I wonder how she'd react to you using what she taught you on someone else)
