Having a big dick in my mouth is the best way to get me to be quiet, but even then I'll be making noise. It never occurred to me to cover my mouth or put a gag in it because I love verbal sex. The first time I tried it was when I was 15 and he was 17, and I was spending the night at his house. We had smoked some weed and were making out on his bed while his family were sleeping. We had smoked some weed which always made us horny, and since we had blown each other earlier, we decided to fuck. He wanted to fuck me first on his bed. I knew what he liked, so I laid down on my stomach on the bed so he could pound the shit out of me & my prostate. Not long after he entered me and began slowly grinding up & down, we heard his mom in the hall. I was whimpering and the bed was creaking, so he reached into his nightstand and took out a small wash cloth. Before my mind could process that this was one of his cum rags, he shoved in my mouth. It was crusty and reeked of cum, and I nearly passed out from pleasure. I grabbed it with my hand and moved it around in my mouth tasting the familiar taste of his cream, and the smell was beyond words. Before I wanted to, I was cumming like crazy all over his bed. We always fucked using condoms, less messy and safer. He was mumbling and swearing quietly as he got close, so I put his cum rag in his mouth. Well, that did it! He cried and whimpered as he blasted in my hole, I'm surprised the condom held up. He said he had never tried his own cum, but he loved it. After that night, we would exchange cum rags. He liked to call me when he was beating off sometimes, with my cum rag in his mouth, and I would listen to him shoot off.
