If you happen to still be taking requests, I would love a fic where Diavolo and MC/reader get back from a nice date. During the date, Diavolo texts Barbatos that he plans on asking MC/reader to stay the night, and Barbatos warns him it will likely hurt MC. Diavolo says he will be careful. So when Diavolo is fucking MC, he gets too excited and does hert MC. Barbatos, being worried for MC, is lingering hear by (I pictured it being in a suite at Hotel Corvo and Barbatos’s room is just across the living room from Diavolo's) and hears MC cry out in pain. Barbatos wants to save MC, but this risks upsetting Diavolo and/or being injured, and sits frozen with indecisiveness while MC is screaming and pleading.
