Sister’s pink panty briefs

You look down at what you are wearing: hot-pink cotton panties. They are just a little too small for you, leaving very little room for your penis. Your penis is fairly average in size, just over 3 inches soft, and 5 or 6 inches hard. You can see the little bulge your soft cock makes in your — well — Jane’s panties and blush. The sight of the pink panties causes you to flash back.
