[Zaki Zaraki] Shougakugakusei Ch.1 - Everyone is Crazy

Young Sae learns at her own father's bedside that family affection has no limits, her guilty protests dissolving into breathless demands as he coaxes her toward climax. A visit to an old friend's home reveals the true arrangement: two dads with identical appetites who freely trade their daughters, with Sae eagerly riding her friend's father and begging to be stretched to fit him. The chapter closes on Sae and Hikari locked in a kiss, both drenched from head to toe, while their guilt-ridden fathers reassure each other that in their world, everyone is doing it.
