Taking advantage of his mother's absence, he secretly engages in unprotected sex with Yurika-neechan next door at her home. "My first time will be without a condom,♪" happily accepting his virgin penis inside her, she moves her hips vigorously, thrusting hard until he finally erupts with a hot release inside her.
