[Tokiwa Yutaka] Hajimete no Konna Kimochi (Magazine Cyberia Vol. 138)

A bespectacled, well-endowed futanari cousin visits her family home to check in on her petite relative, only to find herself swept up in a mess of pent-up tension and unsatisfied desire. She soon discovers the gap between them runs far deeper than just size as her cousin's soaked pussy and trembling body beg to be bred. With a sharp, dominant edge and a cock that demands constant attention, she proves that the most intense first times often happen when family lines blur.
