I answered the door to see Michelle and her mom Miss Brooker. If I didn’t call her Natalie or Nat then she insisted that I call her Miss and not Mrs. as she had been divorced for over a year. I invited them in telling them that Kira, my sister, was still in her room getting ready. Michelle headed to her bedroom carrying a backpack and an overnight bag. “Natalie you look very nice today.” She did too in a pretty strapless sun dress and white leather sandles.. She is a very attractive M*** and my balls were tingling. “Oh thank you, that’s sweet of you to say.” I offered her coffee or juice or something and we made our way to the kitchen. Being 18 some might think I was being a little forward to her but I knew that girls of any age love complements, and Nat was a looker with a well kept and petite figure I knew was 33. She had Michelle at the young age of 21. She accepted some OJ and splashed a little vodka in it. I joined her except with white rum. We got along well and sometimes we were a little flirty but I could never tell If I should kiss her or not. We were almost never physically close enough to just take her in my arms, or if we were we weren’t alone so I hadn’t made a move. She was taking the girls shopping for new swimsuits and a small pool party with 2 more of Kira’s friends coming over later for a sleepover. They all left which gave me time to run to a couple stores myself then get a shower.
Almost 3 hours later 4 nubile 13 year old cuties were running around in bikinis nearly naked and Natalie and I were watching them out a window while I fucked her like crazy from behind bent over my sisters bed. Her own new bikini lying on the floor. We had both c** at least twice when the girls started heading inside. We think they knew something was up but we covered it up well by suggesting that we start the cookout.
