Amateur Male Participation Project! The fourth installment of this popular project! Super beautiful girl Mari-Chu aka Mari Rika, who can do anything, is back with a bang! She has shown that she can afford to cum more after seeing her previous works in this series, so we have carefully selected only the hard-core fans who wrote in the questionnaire that they have slow ejaculation, and this hard mode is limited to Rinatsu Marichu only! Despite this, she squeezes out sperm one after another with her hip-swinging bareback technique! But then Rika Marika realizes that she might not be able to do it raw if she doesn't...?
