After school, Ai witnesses Meari masturbating with her nipples in a classroom, becoming aroused herself. Ai then watches as Meari continues, stimulating her nipples until they become erect. Ai then uses her tongue to lick Meari's erect nipples, coating them with her thick saliva, intensifying the sensation for Meari. Unable to resist Ai's teasing tongue techniques, Meari eventually reaches a nipple orgasm.
The roles reverse as Meari uses her long tongue to stimulate Ai's nipples, causing Ai to gasp and moan from the pleasurable sensations. Ai's sensitive nipples quiver and spasm as they are licked, ultimately leading her to an orgasm from nipple stimulation.
