One day, my brother-in-law Hiroki came to my house suddenly, asking if he could stay with me. When I heard the story from my husband, he said that he had gambled away all his money and was kicked out of his apartment... At that age, he doesn't have a permanent job and was fired from his part-time job... I don't really like Hiroki, who is sloppy. If he wasn't my husband's brother, I couldn't stand living under the same roof with someone like that. After that, I started to feel lewd gazes while taking a bath or doing housework... My husband didn't try to cover it up, but he tried to comfort me... But maybe because he was tired from work, he hadn't had any energy down there for a long time... As usual, I was comforting myself next to my sleeping husband... I had no idea that Hiroki was watching me... And then, when my husband was away, Hiroki came to me... I resisted desperately... However, as he licked my nipples and clitoris, a long-awaited pleasure welled up inside me, and my body began to accept this man... As soon as he inserted himself in me, I couldn't help but moan, "It feels good..." From that day on, I became a slave to carnal desires, and I began to serve Hiroki as he asked, whether my husband was there or not...
