From Create Your Own Story
Harry knows he needs a little less stimulation if he's going to continue. He pulls his face from Ginny's delicate breasts and turns to face both her and Lavender. He guides them so they're side-by-side on the seat, legs spread apart. Taking Lavender with his left hand and Ginny with his right, he begins to rub at both of their damp pussies. He rubs one finger along their slits, pausing occasionally to tease their clits. The girls turn to each other and begin to kiss passionately.
When their pussies are sopping wet, Harry takes his fingers and plays at the edge of their entrances. This sets the girls off. They moan into each other's mouths and start bucking their hips. Harry takes this as his cue, and he slips two fingers into Lavender's and Ginny's waiting pussies.
He thrusts his fingers in and out, moving them in a "come here" motion at the same time. The effect on the girls is incredible. They are both moaning and gasping with pleasure. Lavender begins to fondle her own tits, and Ginny rubs her hands all over her body, enjoying the myriad of sensations. Harry keeps up this assault until he feels their pussy walls tense and then sees both Ginny and Lavender slump in relaxation.
Now that the girls have come, what does Harry do?
