Mitsuki Akai, the sultry Japanese schoolgirl, decides to skip class for a more enticing lesson - an intensive study in deepthroating. Her partner, Kei, is more than willing to be her professor. Mitsuki, with her long, silky black hair and innocent yet hungry eyes, takes Kei's massive cock into her mouth, inch by inch, until it hits the back of her throat. Her wet, warm mouth creates a suction that has Kei groaning in pleasure. Mitsuki's expert tongue flicks and swirls around his shaft, making him throb with desire. She gazes up at him, her eyes watering slightly, but she never loses her rhythm.
