Together with her thumbs hooked into the panties she raised her 40+ buttocks just high enough to pull the panties past her buttocks onto her thighs. Never taking her eyes off of mine my sister slowly pulled down the panties down her thighs to her knees. Instead of bending over to pull down the panties, the biggest shock came after she pulled up her knees to her chest. With her legs bent at the knee, she simply as gradually pulled the panties down her legs. Keeping the eye, my sister pulled one of her pretty feet, coated in high heel sandals from the panties, then stopped to hook the panty on the hint of her other high heeled foot. Maintaining one knee to her torso, she extended the leg together with panty on her own foot. As she did this she ran her hands up her thighs as she spread them exposing her totally bald and gorgeous pussy to me personally.
My sister stopped her foot as it was pressing on the bulge seeking to rip it is way out of her panties I was sporting. Using her foot and the panties she'd only removed to rub my stone tough, panty covered dick she proceeded to rub her thighs with her hands, keeping contact.
She also gave me a while to adjust to the total scene before finally asking me to put on the panties she had just taken off.
With her hot panties that close to my face that I could now feel the warmth from her pussy and enjoy her hot, wanton, aroma as I rubbed her leg. With my tongue to explore the crotch of her hot panties I managed to taste my sister's sweet juices from her sexy panties.
Continuing to utilize my tongue I pulled the panties closer into my mouth then cowgirl (supplemental resources) applied my lips and teeth to pull them into my mouth.
My thick, incredibly hard, dick virtually jumped out of the underwear and ripped like a diving board. I pulled the underwear down low enough that I can slip them off. Together with my sister's high heeled foot resting on my chest, I increased my knees before taking her panties from the mouth. I stayed in that place since I took the panties out of my mouth to put them on. My sister and I never lost eye contact, along with her high heel covered foot never left my chest, in fact I leaned forward some more to be able to rise the pressure of her heels into my torso.

As I did this my sister talked again. Now that you have my underwear, is that in which you want to stop?
I was again shocked, but not shocked that I wasn't able to observe the significant jolt of my dick that pushed out my sister's panties cowgirl far enough that my bulbous dickhead trapped out of the very top of the underwear.
