Sister's room.

You decide to drop in on your older sister. Clearly, something weird is happening and the best way to work out what will be to experiment, and who better to do it on? Of course, she's asleep, which is understandable given the time, so, you just let yourself in.

A rainbow assortment of thongs, G-strings, boy-shorts and other panties are covering every flat surface in the room and a range of bras, from plain to fancy lace, are hanging from every knob in the room apart from yours. Clearly, your sister, Natasha, has been victim of a hurricane with a panty fetish.

Making your way over to the bed, you see your sister, fast asleep, wrapped up snug in her bad. You gently lift the covers off her, leaving her beautiful body on full display, as she lies on her stomach. Now, you see she's wearing only a blue t-shirt and a pair of pink boy-shorts.

Her little pink boy-shorts really seemed to be struggling to contain her pert behind. The smooth, golden tan she has making her legs look even more enticing.

You start thinking about how many guys fantasise about her body, seeing her like this and be able to just reach out and touch any part of her flawless body.

Too much to resist, you lightly stroke the silky skin of her lush behind, or, at least, what her boy-shorts let you get at. Emboldened by the sensual smoothness of her buttocks, you side your hand under her tight little shorts and begin squeezing her perky little posterior.

Snapping out of it, you regain some self-control and focus on what you're about to do next.
