How I became a perfect slut. [FMMM] [Masturbation] [Part 1]

Author’s note: Hey there everyone. This is my first time writing an erotic story, so I’d love to get some critique on this. Both on what I did well and what I could improve on. In any case I hope you guys enjoy my story. Have a nice day! <3

**Chapter 1:**

It was just the day after my 18th birthday. A warm Saturday evening, my mom had gone out, both my older sisters had already moved in with their boyfriends. It was just me, my dad and his two best friends he had invited over to watch some football matches. I was in my room, relaxing in my bed, wearing my comfy black sweatpants with an equally black thong beneath, while my upper body was only clad in a loose pink tanktop. It wasn’t like I intended to go out today, so I figured there was no need to dress myself up all that neatly.
