Awakening the sensuality of the innocent and cheerful smile of the beautiful girl 'Miho Nana' rather than developing it! This work perfectly captures her state. In a state of maximum restraint and impatience, Nana is repeatedly teased and kept waiting! As her movements gradually become more intense, she is suddenly subjected to vigorous piston-like thrusts, fiercely stimulating her uterus. With aphrodisiac oil enhancing sensitivity, from the M-shaped restraint to toy torment, she leaks love juice noisily, and with double piston thrusts hitting the prostate, she repeatedly reaches climax. Behold her growth from undeveloped to lascivious!
