It all began one hot summer afternoon in the backyard pool. Kristy, a friend of my wife, and her friend Corrie had dropped over for a swim, but my wife happened to be away for the afternoon.
I invited them to stay anyway, seeing as how it was such a beautiful day for a swim. The girls were both in their early twenties, and I was about 36. Kristy was about 5'6 and thin, with small breasts, about a 32B, but she had an amazing ass, firm and round. Corrie was an inch shorter, with a pixie cut, smooth white skin and 34C perfectly round orbs. She had perfectly shaped legs and a nice ass, although not as round as Kristy's.
I watched both girls as they peeled off their tank tops and shorts. Kristy had a modest 2 piece bathing suit and Corrie had a bikini that showed off her amazing curves, especially her amazing boobs.
We all jumped into the pool and swam around and cooled off, before I playfully splashed Kristy. Corrie came up from behind and jumped onto my back, trying to pull me under. I felt her breasts pressing into my back as she struggled to get me down. Kristy swam over and grabbed me around the neck from the front, and we all went under. I flailed my arms, pretending to be shocked, and felt my hand brush against Kristy's ass.
We continued fooling around, both girls attacking me, and I took advantage grabbing anything I could. At one point my hand went inside Corrie's bikini top and I felt her nipple against my palm, and it was nice and hard. I glanced up at her and noticed a big smile on her face, so I moved my hand slowly, massaging her breast.
Kristy noticed this as well, and then I felt her hand grabbing at my crotch. She began caressing my penis through my shorts, and between that and Corrie's firm round tit in my hand, I was rock hard in seconds.
Corrie then reached behind and unsnapped her bikini top and let it float away, revealing her full round beautiful boobs, with large brown aureoles and hard nipples. My hands immediately went to them, massaging them firmly, even a bit roughly. She moaned and leaned in to kiss me, open mouthed, her tongue snaking in to play with mine as her hand joined Kristy's on my cock. Kristy went under the water, untied my shorts and pulled them down, gazing at my hardness as she did.
I couldn't believe what was happening, and I knew I should stop, momentarily thinking of my wife, but with these two hot young women with their hands groping and stroking my hard cock, there was no way I was going to stop.
Kristy's hand slowly pumped my shaft as I continued to fondle Corrie's luscious titties. It wasn't fair that I was naked and they weren't yet, so with a giggle, they both shed their swimsuits. My eyes went to Kristy, seeing her small boobs, like I said earlier, 32B, but she had amazing nipples. Long and hard and very suckable, which I immediately begin to do.
