Yuu is so happy he gets a chance to share a picnic with his mommy and his two teachers. But the food makes Mommy sick, and she has to go poop between the bushes. Turns out Mr. Sakaki, one of the teachers, is a pervert that loves to film girls when they shit and pee, and he gave her some laxatives to make her go really bad! Her picnic ends up turning into a hardcore gangbang as the teachers and Yuu fuck Mommy in all her holes and drench her in sticky cum!
