First time I was fucked... 7th grade I put lotion on a knobbed handled screwdriver and fucked myself. I moved up to a thick cordless screwdriver later that year. Nothing happened till my 30s. When I bought my wife a dildo, she said it was too big for her and wouldn't touch it. I was able to take the whole thing and came quickly each time.
Two years later, I was in europe and found an all-male sauna. Put my clothes in a locker, got a towel and a condom. An older grey bear named "Jules" grabbed my ass as I walked by and separated my cheeks, playing with my hole. I told him it was my first time.. he used a condom and a lot of lube... slid right in without effort from my years of training. We fucked in so many positions I lost count. He wasn't big enough to make me cum and he never came. I felt differently towards women and just could not cum with women.
But... last year, there was a cute guy in the Macy's men's room. We kissed and would make out before sucking each other off. One day, I went into the handicapped stall, bent over and let him slide in raw. Once I felt his skin on my skin, I shot ropes of cum on the walls and floor. He pulled out and did the same. The next day we did the same. I wish I had his number... After Rob fucked me raw, I was in a southern ABS and a giant cock slid through the glory hole. I sucked on it to get it wet, turned around and let him slip into my ass. I was addicted. Three days later, I returned to the ABS and an older daddy fucked me raw for an hour. I don't think he came in me but he lost interest and got soft. Maybe he did cum.
