The refined and friendly younger sister-in-law, 'Arisa,' is popular even outside the family. However, there's a secret between her and me that our family doesn't know about. I accidentally saw Arisa having an affair with her girlfriend's real brother. Using this as leverage, I've made it so she's at my mercy. Though she initially puts up a reluctant front, it's clear she's completely smitten by my impregnation training. Nowadays, she sends me M-like glances while pretending to resist, eagerly awaiting the intense punishment and leaking her love juices. Soon, I'll show off how I freely train her slim body that doesn't match her F-cup breasts in front of her brother.
