ERDM-037 - Extremely thrilling situation where discovery is absolutely forbidden! Mother and son's dangerous sexual encounter for 4 hours

Sneaking into the mother's body next to the father sleeping beside her, licking and tasting the ripe vulva. Licking, and then thrusting in at once into the wet area. A scene of intense, wordless entanglement in a situation where no sound can be made. Knowing it's wrong, but faced with the penis, she says, "Don't tell Dad! Just this once..." A close-kin work glimpsing the sexuality of a mother who cannot refuse.
