MFYD-208 | "Did his little guy get all big while we were on a family trip...?" My nephew's erect penis was poking out from his ill-fitting underwear—so I took it upon myself to stroke it for him, over and over again, all without my sister ever finding out... — Kanae Yumemi

One summer vacation—Kanae set off on a family trip with her husband, her older sister, and her nephew, Takeshi, who is now a university student. While they were in the car, Kanae caught a glimpse of something that made her look twice: Takeshi’s "cock," standing so erect and large that it was bulging right out of his shorts! "It’s alright, just leave it to your auntie..." Kanae said, gently offering him a handjob—but that was only the beginning! Whether they were at the pool, during a nap, or in a mixed-gender family bath, Takeshi’s erection simply refused to subside. No matter how many times she tried to "relieve" him, his cock kept popping back up, driving Kanae’s own desire to a fever pitch... Featuring Tameike-exclusive talent Kanae Yumemi, this story showcases her maternal instincts in full bloom—the ultimate summer!
