My 18th birthday gift: Grandfather's first time with a teenage girl

On my 18th birthday, my parents surprised me with an unexpected gift from my grandfather. He had always been a bit of a perv, but I never expected him to actually want to have sex with me. At first, I was horrified and didn't know what to do. But then I realized that this was my chance to finally lose my virginity and to get some experience before I started college. So, I decided to give in and let him fuck me. It was a strange feeling, being with my grandpa, but he was surprisingly skilled and took his time to make sure I enjoyed it. After that, my dad joined us and we had some hardcore sex together. It was an interesting experience, to say the least, but I'm glad I did it. Now I can say that I've been fucked by both my dad and my grandpa.
