Zoe looks at her older brother with a grin. Thinking of a way to him drop down a peg. He has always tormented her over the last few years since they gotten bigger.
"Put the on" she commanded
Jon gulped, his mouth wide open stumbled at his words to to respond. "Ummmmmm what"
Zoe looked at him smirking, enjoying his reaction responded more sternly.
"Did I stutter Jonny boy, you agreed to do anything. I said put them on. Now! or I am going to tell Mom."
Jon felt an odd combination of excitement and fear wash over him while rubbing the satin panties between his fingers.
It was like a trance and before he could realize what he was doing he unbutton his jeans that fells to the floor.
Jon stood there and tried to gather what courage he had left. "Can you at least leave while I put them on? he replied timidly.
Zoe, with a sly smile. "I am not leaving but I will close my eye, hurry up".
Jon waited a second till she closed her eye and quickly removed his boxes. Followed by stepping into the purple lacy panties. He looked down as he pulled them up, feeling excitement as he slowly slide them up his leg. He was almost done when he heard from Zoe.
"Ohh my god your dick is so small" She giggled. "Did you even hit puberty?"
