It was brilliant. Id never felt that full and had a cock so far up inside of me. The only problem was he was a virgin and my 'first' big dick experience didnt last that long thankfully the more sex we had the longer he lasted
My current GF has told me (and I believe her based on the intensity and number of her orgasms) that I was the best she'd ever been with although not the biggest and I've got all of 5.5" in length.
Yes I too get my girl off a lot but that is because I found just the right spot to hit but I know I can't "Fill her Up" like some of the women like i hear they love that real full feeling I guess being male its hard to understand how a penis feels to women but its fun to hear what they like
My first big penis was amazing. I first felt it outside his pants and could tell it was big. It gave me a turned on feeling that went into my stomach and made me a little short of breath. When I first saw it, the feeling intensified and I was nervous to touch it. I had no trouble taking it in since I was so turned on. It filled me up like I hadn't been filled and I loved it!!
My first time with a large cock was amazing... it was awkward, but the sex itself was good. He was 8x6, and I loved feeling that full...
I had a similar experience to Meg. I should mention that it was awkward not because of his cock size, but because we were in the front seat of his Toyota Celica hatchback. I'm 5'8" and he was 6'4", good thing we were both young and limber.
