We were in Mexico and our wives got friendly. My wife an athletic brunette with big boobs. His wife a tight little blond with sweet perky tits and an insane ass. Her husband, much older, black, athletic, a competitive distance biker.

A few nights in and things got sexual. They were swingers we are not. They convinced us to try same room sex. We fuck. I can't take my eyes off his wife's ass, her bald pussy split wide by his huge black dick I cum hard, real hard inside my wife.

My wife and I settle in and watch him fuck his wife for an extended time. My wife nearly drooling watching his cock work. He finally pulls out and lets loose with a huge load all over his pretty wife.

Two nights later we were hanging again. We were in our suite when the ladies started getting amorous. We ended up sharing our king sized bed as my wife and I sucked and fucked while our friends did the same.

While I was fucking my wife, our friend's wife inched over and had her head on my wife's stomach while her husband fucked her. While we were going at it, my wife rolled over and I took her deep doggie style. To my surprise she started sucking on our friends little tits, really getting into it. The sight drove me crazy and before long I was shooting my load.

After I came I sat back to watch out friend's fuck. My wife was curled up absent mindedly playing with our friend's nipples while she intently watched our friend's big black dick plunging in and out of his wife's tight little pink snatch.

His wife came several times then he got close. To my surprise my wife slid right down to where she was mere inches away from our friend's genitals. Her eyes were on that black pipe. As I watched he started hooting that he was going to cum. I heard my wife say "Let me see" and he pulled his dick out of his wife's pussy with a squeal. I saw the tip of his cock grow wet just as he started to cum. Before the first spurt erupted my wife was on his cock, taking it into her mouth and sucking it hard. He yelled and grunted as he filled her mouth with his cum. When he was done and he collapsed on the bed I realized my wife had swallowed his load.

I was shocked. I couldn't say anything because we were all sharing the bed. The next day she said she just got caught up in the moment and said she couldn't help herself. We've been home for three weeks and I can't get the image of her swallowing his cum out of my mind and she confessed to me that she's interested in exploring couples sex some more and even said she's been fantasizing about black men a lot lately. I'm not real sure where to go with this.
