Shingo had been avoiding his crude, shameless, and immodest aunt, Akane. Yet before he realized it, he found himself unconsciously staring at her plump, exposed buttocks peeking out from her revealing clothes. Though he couldn't easily complain as a temporary resident under her roof, he knew his body wouldn't withstand this tension much longer. Akane, indifferent to Shingo's discomfort, freely entered his room and behaved in increasingly lewd ways. When Shingo finally snapped and tried to drive her away, she instead began to tease and touch his crotch. In that instant, long-buried emotions deep within him began to awaken.
