For men and women who want to have sex, nighttime rape is an easy target for relatives such as daughters, mothers, wives, and grandmothers. There are also many cases where older women, feeling safe with their relatives, resort to the drastic measure of reverse nighttime rape, to relieve their lust, targeting uncles, fathers-in-law, sons-in-law, and grandchildren who are the targets of their uncontrollable desires. The fourth volume focuses on nighttime rape, and includes two documentary stories about forbidden stories of grandmothers who raised their grandchildren in place of their busy mothers, but who fell in love with them so much that they became inseparable carnal relations. Enjoy the fourth volume of the hit incest series, which features the shameful nighttime rapes and documentary stories of 13 sexy women, including wives, mothers, cousins, grandmothers, and grandmothers, selected from their 30s to 70s.
