Ah- yes, another one of my guilty pleasures.
Scientists made human-beast experimentations and kept them within a walled-off area so that they could monitor their subjects. One day, our mc entered a hole in the wall (she didnt get stuck dw) because she had to return a kid's ball, but she got lost when she got distracted by the scenery. Now she is staying at a wolf beast's house; ah- but ofc, it just so happens to be their mating season.
The overall story and execution was really well done!!! I enjoyed every bit of it ^^
BL isekai; slave x beastmen. Threesome? Mc got isekaid, regained his youth, and became a slave. One day, a bear beastman bought the mc and freed him from slavery
