The chick has no problem taking it in her mouth and sucking it, she cheats on her husband knowingly. If she needs to swallow, she swallows, if she needs to expose her buns to passing motorists, she'll do that too. The blonde acts like a bitch, ready to do any order of her lover or master.
Yes, the guy has an iron stamina, most would have poured cum on the brunette during a blowjob - impossible to restrain when such a beautiful sensual and smacking pleasure sucking your dick. The rest would have given up in seconds just from the sight of her divine behind - you wouldn't even have had to put it in! But this one did well, withstood it all and won the grand prize.
The dark-haired girl did not expect such a turn of events, but she was not confused. A threesome she would remember for a long time.
