It was fixed and she was on her way. I turned around and headed back home.When I got home I headed for the garage. We have a 23 cubic foot freezer in ...he garage and we always have bags of ice in it and I figured that a party was going to need ice so I went and got a couple of bags. As I was walking up the back steps with the ice I glanced in the family room window and stopped dead in my tracks. Through the window I saw the two guys who had arrived before I left and they had Char between them.. I looked over at my sister’s skinny naked body. It was so nice I just wanted to mount her right then and there. I started to get a boner though so I tried not to think about such things. To distract myself I grabbed a blade of grass. My sister’s eyes were closed, so quickly but quietly I brought the blade of grass up to her vagina. I lightly fluttered it on her clit and she gave a yell and sprung up.“Omg!” She yelled and punched my shoulder, “I thought that was a bug you jerk!”“Hahaha!” I. The cake was all sliced already. I returned with another massive piece of cake. In just my short time away, the girls' conversation had shifted."They don't get that big," strongly said Kayla. "It's hard enough shoving a tampon up there." I'm telling you... ," said Stephanie.I sat down quietly. Like any guy my age, I had a strong curiosity about female anatomy even if the word "tampon" was in the conversation."I once accidentally saw my Dad's," said Courtney.Kayla shook her head refusing to. Now I started removing the hooks of her black blouse one by one , and removed that threw it on the Table, She was now in her blue petticoat and her black bra. I then caught hold of the strings of her petticoat and gave it a pull and it fell down. Now she was just with her black bra and a orange panty. Can you just imagine the figure , so sexy , I just wanted to all the activity with her right away, but slowly started kissing her all over and brought her to the sofa once again and made her lie.
