that's absolutely fine by me and almost certainly for the girls also.
Some girls don't want to cum, particularly early in the working day, some have told me it makes them lazy or sleepy afterwards. They're there to earn money, so don't want to jeopardize that.
Others just get carried away and some actively want to cum. I have found girls can be quite relaxed about this at parties. There are a number of guys who have no interest in the girls' pleasure and are happy to pump & dump, which is fine as that's what they've paid to do. The girls are happy to service these guys, but sometimes they get quite aroused and want to reach a climax.
At one party, after I had cum and was recuperating I set about a girl who is often very responsive, after some RO plus G-spot stimulation she convulsed into orgasm gripping my finger as her hips rolled along with the gasping and panting.
Another girl saw this and wanted some of the same, so she went off to the bathroom to freshen up and called me over to her bed. I worked her for what seemed like an eternity, my tongue was aching, but just as I was flagging, she said don't stop and soon after rolled into a thigh-clenching, finger-gripping orgasm. For a minute or so, she was too sensitive to touch, but then she told me to carry and a few minutes later rolled into an even stronger climax...she obviously needed the release...I was glad to provide it during my downtime.
Another time I was with a girl who is quite reserved and doesn't usually get too aroused by the action. I started dirty talking her, she was liking it as I described what I was I was doing to her, how it was making me feel and how it might be making her feel. This seemed to get her going and she was screwing her face up, panting, groaning, closing her eyes and then looking up at me as I thrust deep. She seemed to be getting more & more aroused and started writhing around underneath me, wrapping her legs around me, her hands were running all over her face and through her hair as she gasped and screwed her face up...she obviously needed it too!!
This doesn't always happen...it took me nearly a year of punting to have a girl genuinely orgasm and in over 400 interactions with over 160 girls either at parties or 1-2-1s in the last 5 years, probably less than 20 (12%) girls have orgasmed and even then , not every time I met them. I'm getting better at it though, firstly at spotting a girl who is receptive and then finding out what it takes to push her over the edge.
Of my reviews, Shakira, Naomi, Jai, Isabel Dean, Nicole, Rosalie & Milla climaxed...but none of the others did...either because there wasn't time or they weren't inclined to...so yes, nice when it happens and I often go back for more, but not the be-all & end-all of punting.
