A huge ejaculation on my spouse's breasts at Cap D'Agde seaside

My wife and I are swingers and we love to explore our sexuality in public places. On a recent vacation in Cap D\'Agde, we decided to have sex on the beach while a couple watched us. My wife gave the man a handjob and then he fucked her while I watched. The guy ejaculated on my wife\'s tits, which made me very horny.
