I’d be lying if I said that never happens, esp if it’s a gangbang or a train but it is quite rare. I do have to take breaks from wanking sometimes though, and I love a clean up break. Also, I’m not furiously jerking, it’s more of a slow wank when I’m watching. If I do cum, I don’t lose interest but it does detract from the pleasure I get until I’m hard again though. And at my age, I’m never certain how long that will take. Sometimes I can get hard again quite quickly, other times it can take me quite a while. But it’s also less enjoyable when it comes to my turn because although I’m usually able to cum again, it’s not as intense as the first cum. That said, if I know it’s going to be a long session, I’ll pop a Cialis, then I’ve no problem getting it up again quickly but it still doesn’t make up for the lack volume if I’ve already shot my load. That sadly is just down to age.
