FNS-269 Summer vacation was supposed to be a fun trip. An apology from the uncle she once adored. Misaki Sonoka

A one-night, two-day trip to visit local art museums that was originally supposed to be taken with her mother. But due to an urgent last-minute matter, her mother can no longer go, so Sonoka consults her kind and dependable uncle. Being a good-hearted man, her uncle gladly agrees, and the two set off on the trip safely.

After enjoying the museums that day, they discover that, due to her mother’s mistake, only one hotel room was booked. Sonoka ends up alone in a room with her uncle. Feeling reassured because he is her uncle, she lets her guard down. Meanwhile, after his bath, her uncle begins to see Sonoka in a different light as she appears in light clothing…

The desire he had kept hidden inside begins to surface. Though still retaining a little reason, her uncle becomes overwhelmed by his feelings.

I’m sorry… I’m sorry for doing this…

Even as he apologizes, he continues to take advantage of Sonoka. Again and again, she is forced to submit, gradually giving in as she accepts his apologies and advances. A relentless, forceful encounter unfolds.
