Bestie asked me to paint her nails and I had fun!! [Beta Moment]

I am in love with my best friend Cait(26f) but she I can never get her because she is in long-term relationship and just calls me her brother every two days to put me in my place I guess. Anyway, she just looks so sexy, she has those cute curls, just the right amount, slightly chubby cheeks, gorgeous tits, long fingers, spankable butt and extremely kissable lips. I get turned on her just by looking at her adjusting her hair!! She randomly talks about her sex life and how her boyfriend is gonna devour her bodyy todayy or how it feels to suck a dickk, or where her bf is getting condoms for laterrrr! Her voice is also so sexyy, so It turns me on soo muchh when she speaks anything related to her sex life!! All I can think is how her bf would make her moan in her sexy voicee when he lickss her outt while she holds his head. And also one day, I was at her place and she said it has been a while since she tried on nail polishh and took out a small bottle. I was looking at herr just admiring her when she turned and asked me, do you want to paint my nailssss? I was so happy when she asked because I got to hold her hands, feel the softness of her skin on me! She held her hand out, I gently grabbed it and painted her nails one by one!!! She had long fingers and my mind was spiraling! I started to think what if she plays with my nipples afterrr, flick ittt and see me moan for herrrrr orr caress my balls and my cock with those pretty handsss! Ahh what could have beeenn, after I polished all her nails, she was very happy, she rubbed my head, hugged me and saidd thanksss darling!! My dick was hard by the time all of this happened. After I went home, I thought about all this, and imagined her fingers running all over my bodyy clusping my chubby chest and then wanks me laterrr while I smooch her and she moans my namee in that sexy voicee of hers, it was the best wank of my life!
