They were out of the country and I came to recover from a heartbreak, but I ended up riding his cock all night. He rammed into my pussy as I screamed out my lungs, and the next morning, I sneaked out. Did everything to avoid running into him, but I soon find him sitting across the desk as my boss. I tried so hard to resist him, but I couldn't. I fingered myself in my office, shamelessly moaning his name. Turns out he watched through the camera, and he stopped me from cumming as a punishment for avoiding him. But I defied him, this time I cummed, fingers deep inside my pussy, warm sticky wetness dripping down the floor as I cum despite his raging voice through the intercom. Later, I suck him off to make it up to him, his fat thick cock fills my mouth, his precum spread through my tongue, he cums hard, thrusting into my throat. Then he rewarded me, spread me out on his desk and thrust into my dripping cunt, hard, painful, filling me to the hilt. I know I'm going to hell, I might as well just burn, so I let him use me however he wants. I take his cock without a word, spread for him anytime, until his daughter walks in on us.
