hook up with best friends older brother!!!!!?

[Jenni]

so i like this guy brad a lot and he is my best friends older brother. she told him i liked him last week and he said really? but he didnt say that he liked me back. for the past month now hes been hanging around while i was at her house and he invited me to his friends party. his friend had a bonfire at his beach house so we all went and i was trying to open my can and i couldnt do it so he came up to me and threw me over his shoulder and started running around. he ran right near the water and i thought he was going to throw me in so he put me down and took my drink and started to walk away so i jumped on his back to get it and he opened it and it sprayed everywhere and we both fell on the ground completly wet from my drink and he started laughing at me so i threw sand at him and then he like rolled on me and covered me in the sand. so now were covered in sand and he says "lets get cleaned up" and he threw me into the water. so now were splashing each other and everyone is
looking at us like were retarted. so we go back to the bonfire and everyone was talking about us. so i slept over her house that night and i walked in on him comming out of the shower, he had a towel on. so he says "jenni if you wanted to see more you just had to ask" and then he wipped his towel off and i turend away really fast and he just started laughing and put it back on. i had walked back towards the corner when he did and then he like slipped and was up against me and then i looked at him and he was like i should prob get dressed and he left. so after i go back to her room her mom calls her down so im sitting there and he comes in and sits next to me and he says "the wet look works for you" and then he kissed my forehead and walked out. does he like me or was he just being nice cause i like him?

and my hair was wet when he said that because i had just taken a shower too.
so last night i slept over her house and he picked me up but she was still at practice so we were sitting there and he was drinking water and he squirted some at me so i thought it would be funny to imitate him so i said "brad if you wanted to see more you just had to ask" and he ****** his head to the side and then she came home and was like umm did i interupt something and he was like no and ran away. what do i do i really like him.

im 17 and hes 19. and i want him to say something or do something first so how do i get him too.

and he called me and asked if i wanted to hang out tonight so i said yes so hes going to come over and watch a movie. what are some suggestions, im not used to making the first move so i need some advice
