It was early evening in June, and my sister and her boyfriend were over. He had just come back from the gym and needed a shower (I inhaled the musk that emanated from him... intoxicating!) He asked if he could use the shower. I said 'go ahead, first door on the right, there's clean towels in the airing cupboard.' He said thanks, and looked over his shoulder and smiled at me.
A fair few minutes went by and I was desperate for the toilet. I knocked on the door, and asked Dan if I could come in. He was behind the curtain so he said 'yeah sure'
I entered the bathroom, and there he was, stood on the bath mat, dripping wet, with plumes of steam coming off him. I uncontrollably said 'sorry' and hastily rushed for the door. He said 'don't go'. I turned back, and he pointed at his humungous dick, which was rock hard. He said 'suck me off first'
I smiled with sweet surprise, and replied 'sure'. I knelt onto the cold tiled floor, and slowly took his monster cock into my mouth, and he pushed my head further on, and rapidly thrusted his meaty appendage in and out of my mouth, forcing me to gag.
He flipped me over and told me to cling onto the bath, which I did, and he ripped off my jeans and pants, and plowed into my ass. I shrieked in painful pleasure. He smiled, laughed and repeatedly asked of me 'do you like that' and every single time, between breaths and spontaneous shrieks of euphoria I replied ' I love it!!'
Time passed, and he continued to plow my little ass, getting quicker and quicker, and them turned me over once more, and shot a generous helping of warm, sweet cum into my mouth, which I swallowed. He then kissed my mouth and caressed my body, at which point I spontaneously came into the bath mat, and he left to go into the bedroom to change.
We continued our evening as normal, but I frequently received glances and smiles from across the room, which I reciprocated.
Just before they left for the evening, I felt a hand firmly grasp my right buttock, and heard a deep, forceful, yet loving voice say:
'Til next time'
