EC-098 - Sana being trained as a slut in front of her boyfriend

To treat a beautiful woman like Sana as a sex toy... but to satisfy a cock fully erect from her charm, you have to get tangled up intensely or the erection won't subside. Against a frightened Sana in the dark, I made her squirt through intense fingering, followed by forced oral and rough sex. Sana keeps climaxing while letting out cute, needy moans. Since she's a top-tier woman with a great face and body, the level of excitement is high, but it didn't quite live up to the 'Demon-like Entanglement' promised in the title.
