FNS-189 Eng sub Are you enough for both?

Meguri has settled onto the living room sofa, positioned right beside the door to Haru’s bedroom. Only a short while ago, she had witnessed—almost as an accidental spectator—her sister and her boyfriend having sex with absolute abandon. Any other woman would have felt indignant at such a lack of modesty, but not her; there is no trace of scandal in her gaze, only an analytical curiosity.

Now, wrapped in the heavy silence of the house, Meguri remains waiting. She is not looking to interrupt, but to evaluate. She is there to determine, with almost surgical coldness, whether her sister's boyfriend possesses the stamina and the temperament to satisfy the expectations of both.
