Not super proud of myself but I have had a huge crush on my older sister’s bf ever since I met him. I hear him fucking her in her room sometimes and it makes me very wet. One day when he came over and my sister was out, I told him how I felt and he was quite sympathetic. He told me he liked my sister and I was a bit young and put his arm on my shoulder. I couldn’t resist, I kissed him and when he pulled away, I grabbed his dick through his pants. He started getting hard and that was all the motivation I needed. I opened the button and unzipped his pant, took his very hard cock out of his briefs and started licking and sucking it. I kept sucking him harder and faster and deeper till I was gaging on his cock. He got into it and started throat fucking me and eventually came in my throat. I swallowed what I could and the rest just oozed out of my mouth. I went back to my room and washed up with a huge grin on my face. Haven’t spoken to him since, things are a bit awkward now…
