I had really been looking forward to going to California for the first time with Michelle. We were going to a friend's wedding near Napa and had a great room in a B&B all lined up. Mish was excited about the wedding, and I was excited about the king-size bed, fireplace and stand-up shower in our room. When I found out that Michelle's sister Sarah had booked a last-minute special-fare flight but would be sharing our room, I almost called the whole trip off. That would have been the biggest mistake of my life.
We arrived the night before the wedding, and I was in a rotten mood over the arrangements. Michelle wouldn't even take advantage of the shower with me, and Sarah never took the hints to leave us alone for a while. I was getting frustrated, but made the best of it. Michelle is 5'11", with long dark hair, a long athletic body and the nicest legs and ass of any woman I've ever seen. Her sister is a little shorter and more muscular, with no fat and a set of 36C's that I sneak looks at whenever I can. Michelle and I have a great sex life, but whenever I joke with her about a threesome it really is just a joke- I would never have thought she's even entertain the idea, and she always scowls and slaps me for mentioning it.
The wedding was great, as far as weddings go. The ceremony was short, and the reception started immediately. We all enjoyed the band and dancing, and as I got deeper into the beer and wine I noticed Michelle and Sarah were feeling the effects of the alcohol. They were getting looser and dancing wildly, moving their gorgeous bodies with reckless abandon. The light summer dresses kept riding up their smooth legs, and the heat was helping the sweat glue the flimsy material to their waists and breasts. I wasn't the only guy looking, but the girls were oblivious to all the attention they were getting. Sarah's face was flushed and I couldn't look at her for too long without getting an erection.
When the party finally ended (if you're going to get married, make sure your reception runs from 4 to midnight- your guests will thank you for it!) we caught a cab back to our room. I had a mild buzz-on, but both the girls had a charge going- no one was falling down, but their eyes were glassy and all of us were grinning a little too much. Sarah changed in the bathroom, coming out in a flimsy t-shirt that stopped at her bellybutton and clung to her perfect breasts. Mishy and I had already changed, and while my girlfriend took her turn in the bath I nearly broke my neck switching my gaze from Sarah's white silk panties to her tits. She noticed immediately, and I could see her eyeing my body- we tried to make small talk, but obviously we were both thinking about the same thing. By the time Michelle came out Sarah's nipples were standing erect against the t-shirt and my prick was stirring in my boxers.
Michelle and I crawled into bed, and Sarah took the cot, complaining about the mattress and about being lonely. I think Michelle was joking when she invited her over, but I was hoping Sarah would take her up on it. I got up and went to use the bathroom and brush my teeth, and when I came out they both had wicked little grins on their faces.
