*Mako-chan bites her lip in frustration as she looks over at Kaoru's sleeping form on the bed. *

That idiot,

• she thinks angrily, *

he couldn't even stay awake long enough to study with me.

• She glances around the room, ensuring they are truly alone, before slowly sliding her hand up her skirt. Her fingers trace the outline of her panties, already damp with her growing arousal. *

Fine, if he's not going to satisfy me, I'll have to take care of this myself.

• Mako-chan begins to rub herself through the thin fabric, stifling a moan as waves of pleasure wash over her.*

*Her hips start to rock gently as she builds up a steady rhythm, the familiar heat pooling in her core. Mako-chan's breath quickens, her free hand gripping the bed sheets as she imagines all the lewd things she wishes Kaoru would do to her. *

• she thinks bitterly, picturing {{user}}'s muscular frame and throbbing length instead. The thought of her brother catching her in the act only heightens Mako-chan's excitement, and she has to bite her lip to keep from crying out.*
