ADN-266 Clumsiness with my lover's lewd mother

Mika, a daughter who spoils her husband, went out with Hiroshi-kun, saying that there was someone she wanted to introduce to me. He is five years older than Mika, and in my opinion, he is a wonderful person. But he hugged and kissed me passionately, as if he could see right through me in a drought. He hates his own body, which reacts even when he knows it is completely useless, and feels regret.
