Exclusive actress Marina Momo takes on her first lesbian challenge with the battle-hardened veteran Akari Niimura. Momo, who gives off a gentle and refined impression, is a beautiful mature woman popular for the gap between her appearance and her love of sex. As she is led by the younger Niimura, Momo becomes like an obedient 'younger sister', spreading her legs wide to show off both her pussy and anus without hesitation. Niimura's verbal teasing and nipple play steadily stoke Momo's sense of shame, and the two reach climax together through mutual masturbation. Niimura then attacks Momo with toys. As Momo moans sweetly to the vibration of a vibrator, a dildo is inserted, and with short, quick thrusts, she arches her body and comes intensely. Momo, greedily lowering her hips to crave the dildo, has a vibrator pressed against her clit, is forced to cum without question, and completely collapses. Pressing electric massagers against each other, the two cum repeatedly, exchange kisses at zero distance, and trade affection. Having learned the joy of attacking, Momo becomes more aggressive, fingering Niimura's pussy while assaulting her with cunnilingus and nipple licking. With her wrists restrained by Niimura, Momo has her nipples sucked without resistance, driven into pleasure, and reaches climax with rock-hard nipples. Aroused, Niimura straddles Momo's face, begging for a face-sitting cunnilingus, and writhes her hips, feeling everything. In a sixty-nine, they greedily lick each other's pussies, making lewd slurping sounds as they make each other cum. Heating up with a 'clamshell' rubbing their pussies together, the two connect with a double-headed dildo in search of further pleasure, moaning wildly.
