HZGD-279 My sister-in-law and I switched bodies and became perverts

Seiya is a young man who lives with his brother and his beautiful sister-in-law. Seiya’s brother is always nagging him because he can’t find a job and spends his time lazing around at home.

One night, a mysterious entity offers Seiya help so he can get revenge on his brother and also have fun with his sister-in-law.

The next day, Seiya and his sister-in-law have switched bodies, and while they try to figure out how to return to normal, they will take advantage of the opportunity to enjoy the pleasures of their new bodies.

Caution! Because this can become very addictive.
