The story of how I fucked my best friend (f/m)

I’d been staying with him all week. All week we’d shared a bed which wasn’t really out of the norm for us but this time it was different. We had been cuddling although really it was just an excuse to get closer to each other and for me to let him touch me however he wanted. All week we would go to bed and he would run his hands down my body, squeezing me and pulling me closer and I would pretend that it’s normal for friends to do this and I would arch my back against him, feeling his cock get hard against my ass, shifting slightly as if I was asleep but really just wanting to know that I was turning him on. A few times he’d tried to kiss me, fingers under my chin pulling my lips up to meet his but every time I had bitten my lip and turned my head away ‘we can’t’ ‘It’s not right’ ‘we can’t go back from this’.
