As collateral for debt... This is the classic trope of erotic dramas. She doesn't want to comply, but she can't firmly refuse either, and gradually falls into the man's rhythm, sinking into a swamp of pleasure. Even without intention, once a hot dick is inserted inside her, she's a married woman—sadly, she can't suppress the pleasure welling up from deep within her body. This is a gem that lets you savor the profound eroticism of such married women.
