There is one word that comes to mind when thinking about throbbing cock cumming inside her - rimjob. When women are rimjobved, it means that she's so turned on that she would be unable to control her orgasm even with all her body to do. Most women who have had multiple orgasms and ejaculations would not turn down the idea of a rimjob - but then again, a thong is more comfortable for a woman to have and the way a man would go down on her that is just a little different from how a rimjob would be performed.
