Those girls are so evil, powerful and amazing at once. I love to watch how they dominate and torture that big dicks. It's wonderful how much fun they had while they're ruining orgasms, it's better then giving pleasure. Sadly only that slowmo replays are not that cool but for that girls we can survive it.
Some of those cumshots looked like the guys hadn't cum for days. Having a beautiful girl ruin what would otherwise be an intense ball-draining orgasm must leave a guy hot, horny, unsatisfied and, with empty balls, unable to gain relief for some time. So cruel, but so deliciously frustrating when a girl chooses not to provide the manual stimulation for those crucial few seconds!
