I just found this very similar manga that came out 4 years prior and wonder if Sensory Sharing Maids was influenced by it: https://mangadex.org/title/c2ac354e-8667-4c20-a7dd-37ab445a5109/heart-synchro. They both have basically identical twins who share sensory feelings and getting affected by the other having sex.
