I held onto her and said "I want you." She got this look of confusion in her eyes.Before she could react I gave her a full open mouth kiss on the lips...She resisted at first,but after a few seconds she whispered "fuck it" and started kissing me back.We started pulling each others clothes off.In a few seconds we were totally nude. I guess this would be a good time to describe what she looks like.She's 5'6" 110 lbs. Long toned legs with an ass made for a thong bikini.Her pussy was totally. Jan was lying on her back, almost spread eagle on the lower half of the bed. Jan had managed to get out of her skirt and was laying in just her tank top and thong.Needless to say I felt a stirring in my boxers when I saw that!My sister must have lasted a little longer. She was flopped face down on the upper part of the bed.She managed to get out of her shorts and shirt and was laying there in just her skimpy panties.Then that timeless.. If she wasn't my sister..... ran through my head.I stood. She is thin and has a stomach to die for. Her firm tits stand at attention and love it! She never hardly wears a bra.My friend Jen and I were so excited. We waited months to buy tickets for the concert.She came to my house that afternoon and we had to decide what to wear to the concert. I decided to wear a really small pair of faded blue jean Guess shorts I had owned for years. They were like my security blanket. I wore them almost every warm day. They were starting to wear and the fabric. Francis this is Dora, Dora meet Francis." Nice to meet you," they chorused to each other. "Nothing's happening," Francis told Ted."Shit... oops, sorry dear," Ted apologized to his wife. She just nodded. "Uh... where's the Thomases?" They left about a half hour ago. Mrs. Thomas is so freaked out that the old man is thinking of putting her into the hospital." Too bad!" Ted shook his head. Dora kept quiet to let the pros do their work.Gladys and Stan held the half sleeping girl as Jim knocked on.
