How should I start physical contact/cuddling?

Me and this girl like each other. We usually text/fb for a while everyday. She has invited me over a few times but I couldn't make it. Now, we have planned to watch the bachelor together next week. She has said stuff like "i wanna be in ur arms" and has heavily hinted that she would like to cuddle and such. how can I start this while watching the show? also, should I be talking to her? sweet talking? or should we just watch silently? I am relatively inexperienced and would appreciate your help
