My sister and I are in our fifties, she is three years younger than me. Few months ago we were visiting out mother and the two of them drained like three bottles of wine one day. Mom had gone to bed for a few hours and my sister and I were talking about growing up and she laughed saying she has never had any other man give her an orgasm like I did. I laughed and we talked some more ending with I would be glad to do it again for her any time.
I got this crazy idea back then after we had been exploring each other over several months, most of it was just quick touch and feel sort of thing. My only sex education came from a stack porn magazines left behind in my dads shop that no one else seemed to know about after he passed away. So one day during summer break when we had hours of time I asked my sister if I could tie her up and play with her, it was a simple set up on her bed because it had bed posts on all four corners. We used a jump rope and some scarves she had and I tickled her senseless then laid between her legs and just ran my finger over and around her clit for quite some time, I would stop and do the same to her nipples then go back to her clit. Drove her crazy and felt incredible all at the same time, finally I licked it hard flicking it all over the place making her scream out with orgasm after orgasm. She told me neither of her husbands were much with foreplay and confessed she had brought bondage with the second one and he just shrugged saying sounded fun but never acted on it.
Last weekend she came over, I found out that she cannot control her pee very well when tickled, she wet herself pretty badly, I didn’t care and got a warm wash cloth to clean her up with then teased her clit for another orgasm listening to her moan and plead to do it harder. I didn’t. When I thought she was really at her wits end I sucked her clit in deep and gave it a tongue lashing until she was having her third orgasm, no escaping for her at all with being tightly bound down to my coffee table where I watched my wife have several orgasms from the same treatment. My sisters clit seemed much bigger than before, sure she has some wrinkles and her breasts are saggy and flat but her nipples are still super sensitive and get pretty erect so a lot of fun to play with for sure. When I finally undid her she let out a long breath saying she needed that so bad and said she would be back for it again next month.
