I have only had this with my very first punter, looking back, I didn't understand why he emphasised it so hard, tbh he did come twice, now with more experience I understand that a bit more now but no one has asked me since. But I did recently have an experience that was like that, rushed, like he wanted to have as many orgasms as possible one after the other and do it all fucking. Zero foreplay, warm up or pleasure, it was disgusting.
