Nikku, her 'educator,' guides Yui's eager hands to his throbbing cock, teaching her to stroke and suck. Asuka, the silent observer, grows wet watching Yui's pussy stretch around Nikku's thickness. Yui's first lesson in pussy fucking leaves her gasping, her fresh cum dripping down her thighs. Nikku's not done; he flips her, pushing her tits into the mattress, and pounds her from behind, making her scream in pleasure. Asuka can't hold back, joining in to lick Yui's clit as Nikku fills her with cum.
