You just made me think of a book I once read, written by an AI researcher and author who wanted to try his hand at a format akin to a Japanese light novel. The premise is a girl who is absolutely depraved and terminally online as an isekai. She literally gets summoned while masturbating, gets asked if she is a virgin because the plan relies on giving her holy magic by binding an angel to her and she has to be a virgin for that to work (and thankfully masturbation doesn't count). The angel is bound to her, which gives it access to her mind, and it immediately begins screaming in horror.
