Wow, sounds like we're cut from the same cloth. I especially like a 69, being on the bottom and having my mouth fucked and cum in. As soon as I feel that twitch and taste that cum, I lose control and erupt.
Same here... never had a real cock in my ass, but definitely willing to try. And I also discovered that I love having a rock hard cock throbbing and pumping hot cum into my mouth while I stroke and slurp it.
I graduated from pussy to sucking cock because I found I like a hard cock pulsing in my mouth and cumming. My next step will be to surrender my ass pussy to feel warm jizz inside me. But not something that big.
