Just barely

Despite this, she came with thirty seconds to spare on my phone timer, crying out in a massive moan as she shook with the biggest orgasm of her life.

Immediately as it subsided she burst into mixed tears of happiness, sadness and relief. I cradled her head in my hands, saying "There there darling, what a good last cum, I'm sure you made the most of it, you'll certainly remember that forever." However I was also trying to be genuinely comforting to her, as I did feel sorry. Nevertheless I reached to the bedside table and picked up the short cuff chain that linked her hands behind her back, and even as I caressed her I gently said "Hands behind your back baby." She sobbed, barely able to pull her hands away from her throbbing pussy, but I gently pulled them and she obeyed. I locked her hands tightly behind her back, ending her last episode of sexual pleasure. She looked truly pitiful, so I kissed her and cuddled her and poured her a glass of water which I fed to her.
