Mitsuki Akai, a Japanese schoolgirl with a penchant for the taboo, finds herself in an unorthodox lesson with Kei. He teaches her the art of deepthroating, his thick cock stretching her mouth wide. She gags but perseveres, her hunger for his cum driving her forward. Her fingers dip into her panties, rubbing her clit, matching the rhythm of her blowjob. Kei, unable to hold back, erupts in her mouth, filling it with his hot, salty load. Mitsuki swallows every drop, her eyes gleaming with satisfaction, ready for their next lesson - creampie 101.
