Hello, this experience took place many years ago when I was eleven. It was Halloween, and I wanted to go out trick or treating, but couldn't think of a costume. My sister, who was sixteen, got this idea to dress me up as a little girl in her old communion dress.
I was bashful at first, but she convinced me it would be great. We went into her bedroom and she rummaged around in her closet and brought out several objects. To my surprise she said I would have to strip, as we were going from the bottom up. I protested and she laughed and said she wouldn't look. She turned round and I removed all my clothes until I was naked. My young erection grew as I picked up the panties she provided, they were white lace with rows of frilly lace across the back. Nervously I pulled them on my body and tugged them up. My sister turned around and grinned, telling me they looked real cute, but I couldn't go out with that! She was pointing to my young erection, poking the panties straight out!
I was very embarassed, but what she did next was shocking! My sis reached out and stroked my erection through the panties! Without another word, she reached inside the panties and grasped my hot little tool, pulling it free. She wrapped her hand around it and began stroking it firmly. I had never had another person even see me erect, let alone touch me, so it didn't take long until I squirted all over her hand. She giggled as I did!
Saying that was better, she wiped her hand off on her bed sheet, then wiped off my quickly deflating tool. She tucked it back in the panties and patted it lightly. Then she handed me a little training bra and helped me pull it on. Next went a frilly full slip with ruffles of lace, and finally the white communion dress. I felt very excited, it was a wonderful feeling. Then she made me sit on the bed and she pulled little white lacy socks on my feet.
When I sat down, the dress and slip had flipped up and my panty covered crotch was exposed to her. Once again I was hard. She laughed again and commented that I was a horny S.O.B. She pushed me flat back on the bed and started rubbing my penis through the panties. Then to my shock, she pulled it out of my panties and stroked me hard again! I had never had two cums in such a short space of time, it was wild. She plunged up and down with her hand and I came very quickly, shooting my load onto my sisters hand and arm!
This was the first and the most wonderful experience I ever had, and started me on a life of both sex and panties. Over the next few years my sis furnished me with many pairs of lacy panties, and several times she stroked me off, never asking anything in return. What a sis!
