Rikku did not care

She scarcely noticed it when you entered from your hidden place, and stood near Lulu, watching, but Rikku did not care. "That's right," Lulu said. "Pump your pussy down onto the dildo. Feel it thrust and wiggle and buzz inside you!" Rikku was pumping harder, now. Squeezing her breasts, grabbing her own nipples through the cloth of her blouse, through her bra.

Lulu looked up at you, and you nodded to each other, smiling. Then she looked back at Rikku. Watching the little slut humping the dildo was getting her so excited, Lulu began rubbing her own thighs together. Her free hand began wandering around her own body, touching and stimulating herself. Rikku pumped and panted. "Good girl." Rikku moaned, she was almost there!

Rikku's eyes went wide, unable to speak, biting her lip. She pumped her hips, unable to stop, and dug her fingers into her breasts. Rikku moaned again, thrusting, pumping. So close! "Closer... and closer... NOW," Lulu said. "I am cumming!" And she was. Lulu squeezed her thighs tightly together, and she felt the orgasm rippling through her own clitoris, her belly -- wave after wave, cresting over and over.

Rikku didn’t approach orgasm, she thrust her hips down, hard, against the dildo, pausing her pumping only a moment. And moaned, frustrated. "Oh, that felt so good!" Lulu cried. And it had. "It felt so good for me to cum again. But you did not yet! Feel the dildo thrusting and spinning inside you!" The bubbly blonde started pumping her hips again. Her little pink tongue was sticking out through her shiny lips.
