EVIS-553 - Sensitive nipple stimulation

Mary is masturbating her nipples in the classroom after school, and Ai becomes aroused after witnessing her. Ai watches Mary masturbate her nipples, pinches the erect nipples to make them firm, and then Ai's free tongue licks the erect nipples. Mary is stimulated by the viscous saliva, making them slippery, and feels even more pleasure. Finally, she can't resist Ai's lewd tongue technique and licks her nipples. In return, Mary uses her long tongue to tease Ai's nipples, and Ai moans from the sensation of the tongue. The sensitive nipples twitch when sucked, and finally, she reaches orgasm with her nipples.
