"Amu," a busty beauty with a 93-centimeter bust and H-cup breasts, attends a national dental university in Tokyo, where she has been educated to take over her family's dental clinic, which has been in operation for generations. Due to certain circumstances, she decides to earn her tuition herself and, after much deliberation, resolves to engage in sexual intercourse with a 'daddy' she found on social media. Although she is earnest at heart, she is also very curious about sex. She proudly displays her voluptuous breasts and uses paizuri techniques while thoroughly licking a long-absent penis. Her wet, sensitive vagina is toyed with, causing her to orgasm intensely. Finally, she experiences the long-awaited pleasure of unprotected, raw sex.
