My tiny mouth loves my grandpa

Dear Journal,
So we went on a family vacation with Grandpa last week and I had an AAAmazing time. It all started when I was hanging in Grandpas room trying to avoid my cousins. While gramps was in the shower I came across the hotel porn channel and figured I'd sneak in a quick orgasm. One led to 2 and before I knew it Grandpa walked in on me. I was a bit embarrassed already then gramps threatened to tell dad and something in me snapped.
I grabbed Grandpas cock through his towel and before he could protest I started sucking it. Once Grandpas big cock was in my tiny mouth he was putty in my hands. I rode him on the couch to get off but I needed more so we moved to the bedroom.
Grandpa really knows what hes doing in bed and has tons of stamina for being 74. I don't know how many positions we fucked in but I came in every one. Grandpa bent me over on the bed at he end and sure enough he came deep in me. I didn't have the heart to tell him I wasn't on the pill. Besides how fertile can his old sperm be? On the plus side I'm Grandpas favorite now and he's loaded.
