She just likes to dress up.

"I think you look really cute," Kako says with a smile. Her skirt is rather large and flowing so it is hard to make out her extra parts. Your top manages to cover your entire chest. Kako pretends as if she is straightening up your clothes, but you can feel her just wanting to touch you all over.
"You are not very subtle," you whisper. Her face reddens and she steps back.
"You just look really hot!" You smile at her and undo a couple of buttons on your shirt. Your parted cleavage comes into view. She looks at your chest until you turn around slowly. You rest your hands on the top on your big butt and give it a bit of a squeeze. Kako gulps. You hook your fingers into the waistband of your skirt and pull it down a bit. Your silky underwear comes into view. Then you slide your waistband back into place. When you look at Kako again, you can see her shyly hiking up her skirt in the front to reveal the largest panty-clad bulge you have ever seen. It literally hangs past her knees. You see a wet spot forming near the end of what must be her penis. You slap your ass and see that spot twitch.
"You really must learn to control yourself, Kako. How will you ever make it in the world like that?" She looks on as you pull down her blue panties in the front and put the waistband under her cock, freeing it but not her balls. Then you lift her leaking cock and go to town on her head. You know she won't last long, so you need to decide: Do you put it away and chasten her? Leave it out and tease her some more? Or perhaps you would like her to cum in your face? Maybe accept her cum into you somewhere? Choices, choices...to be mean or nice?
