It’s about after Spider-Man gets rid of the symbiote venom suit at the church, the symbiote finds another host Eddie Brock who also wants to get revenge on Peter Parker a.k.a. Spider-Man.
instead of giving Eddie superpowers, the symbiote has another idea. Unlike Eddie’s hate towards Peter, the symbiote has an obsession instead. It wants to stay with Peter one way or another.
It first promises Eddie powers and convinces Eddie a disguise is necessary to get close to Peter.
Every Morning the symbiote will transform Eddie into a woman and transform him back at night. Eddie who now has another name, begins to work as a new mysterious female journalist in the bagel to get close to Peter. What Eddie doesn't know is the symbiote slowly feminises him fully into a sexy woman and influences Eddie’s mind to make him think that seducing Peter is the best way to get his revenge.
Peter completely falls for the charm of this mysterious lady. They become extremely close and intimate.
Although Eddie’s mind is under the symbiote’s influence and acts as a perfect woman, sometimes he will realise he is a heterosexual man and resist the symbiote’s influence. But he will always pull back by the pleasure and libido as a woman and submit to Peter in bed. Now he suffered an eternal loop of realisation, humiliation and submission. Soon, he realised he was stuck in his newly transformed body.
Peter never realised his partner for life used to be the combination of 2 of his former foes and a man. Eddie’s personality still comes back occasionally, but his mind has already been slowly feminised to a point where he can’t resist Peter anymore.
