Hi I’m Bill and I want to tell you my story on how I was first laid by the sister of my older brother’s girlfriend. Yes what a mouthful. Mum and Dad were away for the night in the city and my older brother Aaron 17, was told to look after and feed me. I’m 15 and I do know who to get food but mum does not believe it. Anyway my brother went out and brought over his girlfriend Carol 17, but Carol had to have Debbie 15, as a chaperone. Their parents were not aware our parents were not at home.

I was not aware initially of the arrangements. It was after dinner I went to my room to watch some porn movies that I downloaded under my fathers second ID. Yes I opened a google account in my fathers name adding ‘game account’ to his name. I used his ID to get around the porn blocks of downloading adult stuff. I even used his drivers licence as proof.

The evening was hot so I was sitting in bed, dressed in shorts and just a sheet covering my shorts with my hard cock, sticking out of my shorts, being wanked by me. I had ear buds in so I did not hear any noise. My bedroom door opened, but I did not notice as I was deep into the sexy movie. Next thing was one of my ear buds was removed and she placed it in her ear. She noticed the sheet movement and asked “Are you wanking yourself?” as she pulled back the bed sheet.

I was astonished at the view, a skinny girl from my year in school, very short netball skirt and a light yellow t-shirt which showed her beautiful A cup nipples. Seeing me wanking she walked to the door, closed it and placed a chair to lock it. She turned around and looking at me still stunned, she removed her white undies, folding them tidy and placed it in my computer top draw. She walked back to my double bed and asked “Ever been fucked?”

I was still in shock and shook my head more or less saying no. “I’m Debbie, Carol’s sister. They are being too gross on the lounge. Hold your cock upwards.” She entered my bed by sitting down on my cock. I saw the triangle of black hair pointing to her slit. My cock disappeared inside her pussy and she moaned as she slid down my cock. Our pubic bones met and Debbie squeezed my cock trying to milk it. I was no longer a virgin. Wow.
