Here are my thoughts regarding Drew x Ophelia...
We know from teasers that Ophelia and Sterling confront Drew. Drew looks sad and ashamed, as she probably apologizes and confesses to being a sex addict. Drew begs for forgiveness, saying she never wanted to hurt anyone, and somehow convinces Ophelia to give her a chance to repair their relationship. Ophelia says Drew must re-earn her trust, and gives her the chastity belt ultimatum, and Drew goes along with this.
But how does Drew seduce Ophelia? With Hunter gone, I'm guessing the gas or wine won't be involved, not that she really needs them. I was thinking Ophelia might consent out of pity, mainly after seeing the teaser pic of Drew begging. But I'm not sure pity is enough to get Ophelia to go all the way.
Maybe Drew claims that she needs reach orgasm periodically or it causes her physical suffering, so Ophelia allows her to remove the chastity belt temporarily to accomplish this. Then Drew "struggles" to get off, which causes Ophelia to offer her "assistance" to get it over with so the chastity belt can go back on. In the teaser video we see Ophelia getting a titfuck while she has an annoyed expression, I'm guessing this is Drew's point of view.
How do they get from a titfuck to full-on sex? I think this will require some sort of psychological manipulation. Maybe Drew tells Ophelia that David confided he was unsatisfied by sex with his wife. This hurts Ophelia's ego and she fucks Drew to prove that she's a good lay?
