This happened over 10 years ago when Craig's List was till doing personals. I was in Cleveland for work. I had a few drinks and was horny so I started replying to personal ads. I did W4M and MW4M (as you had a better chance of some guy wanting to watch his wife get fucked). This guy replied that him and a girl would come over for $200. I told them I would need to see a pic of her. She called me directly and sent a pic. I told her I thought she was hot but I didn't want to as he seemed a bit weird. It was at that point she made a different proposition.
She told me she had a twin sister and they could come over for some fun, at the same price. Who doesn't jump on that? Of course I said yes. A hour and a half later two beautiful girls (Identical) show up at my hotel door. They come in and don't waist any time. We start making out and they pushed me onto the bed. One straddles my face and the other starts to suck my cock. Then they both start sucking my cock.
They wanted to fuck but we didn't have any condoms so we kept playing around doing oral. They were making out and sucking on the others tits. They wouldn't go down on each other. I jacked off and came on their tits.
The one went into the bathroom and was getting dressed when the other grabs me and pushed my cock into her. We were fucking bareback and her sister cam in and said what about me. I fucked them both, came inside each other them, and then they left.
I was 40, they were 27. It was a great night!
