[Youkandou (Youkan)] Princess♂'s Royal Education

A pampered young prince raised as the royal family's precious princess receives a very hands-on education from his dutiful maid and a commanding noblewoman who insist his training be thorough. Legs pinned wide and locked in a chastity cage, the blushing princess is walked through plugs, beads, and relentless prostate teasing until he squirts helplessly, sobbing for them to stop even as his body climaxes again and again. Every trembling lesson leaves him more thoroughly broken in—suggesting the royal household's tutelage has only just begun.
