IPX-982 My brother's lover is my ex-girlfriend

Seigo went to work in the Philippines for a while and suddenly returned to Japan. Your brother is a very good man, always taking care of you. While he was away, his brother also got married, and when he met his sister-in-law, Seigo was extremely surprised to find that person was his ex-girlfriend! That night, Seigo accidentally discovered his brother and his wife making love, and through his sister-in-law's expression, Seigo knew that this ex-girlfriend was not satisfied. Having not been fucked in a long time, seeing what happened last night made Seigo's sexual desire rise. He risked fucking his sister-in-law even when his brother was right next to her. Even though she couldn't keep saying it, her sister-in-law only superficially stopped her. Even after Seigo had ejaculated, she actively wanted him to fuck her again, and this time she wanted him to cum all over her pussy! And from then on, the two continued to secretly fuck each other right next to their brother who was always devoted to his family...
