Imouto Manual

"Imouto Manual" is an adult manga anthology that explores a series of provocative and taboo encounters centered around sibling dynamics.

In another extended storyline, an older brother decides to push boundaries even further by engaging in escalating encounters with his three younger sisters. The anthology continues with varied scenarios highlighting mischievous and risky behavior.

Elsewhere, a young girl receives a new swimsuit from her brother and his friend, but the gift comes at the cost of providing them with sexual favors. The collection concludes with a tense public encounter, as a brother and sister engage in intimacy inside a public restroom, only to be caught off guard when the sister's classmates suddenly arrive nearby.
