So i fell in love with my dad's best friend

Today I am 18 and my dad is throwing me a birthday party I am not suppose to know but his best friend let slip when he asked what I wanted for my birthday even though I lied to him because all I really want is him he has dark brown hair with green eyes and he works out 4 times a week which means he is mostly muscle and I am in love with him I have been for years. Darren helped me though a tough time in my life and I am who I am because he showed me I didn't have to be that shy chubby 15 year old for the rest of my life I am now a confident 18 year old who can get whatever guy she wants. I have a plan to get Darren to kiss me tonight and hopefully he will find me so attractive that we won't want to take his hands off me and I feel like I could be happy with him I just hope he doesn't see the shy chubby 15 year old anymore. I am wearing the tightest blue jeans and low cut top that show my bum and boobs which are my best assists I have now and I flaunt them when I can and I believe today is the best way to show Darren that I am no longer that shy 15 year old he first met I am very confident now and now I just want to feel him kissing me and his arms around me. I walk down stairs and I see Darren looking up at me with his phone in hand filming me and wolf whistling I can't help but smile because that's all I've ever wanted from him as I reach the bottom of the stairs he turns his phone off and hugs me and I decide this is the time to kiss him and he leans in at the same time and we kiss he then pulls away and whispers in my ear and says "Hey don't tell anyone but I have seen the change and I am glad that I just kissed you because I think we could be together.
