This is a great update. However, I think, at least in my opinion, a few things could make the current update better and what could/should happen in the next update.
This update....the things I'm talking about would be the downfall of David, at stupid and dumb character at the base. In the beginning, where he walks into the club bathroom to spoil the fun. When the security/bouncer walks in to disrupt the scene and to get rid of the people, David, using his arrogance and stupidity, would eventually start a fight with them. He might be able to take out one (or if it was just the main bouncer that was doing all the talking in the update) David would eventually lose. He would be taken out into the back alley the thrown into a dumpster of trash. He would have been beaten so bad that he would lay there for hours, until well after the close of the club. Maybe we would see another cut scene where he is whining to his boss (or whomever he was referring too) and they would basically tell him that his childish attitude is displeasing them and he has been put on a very short string, especially after Ted's debacle.
The next improvement in this update could have been when Jason is fucking Ted's wife, that after the initial fuck scene, we are given control of Jason to fuck Susan even more and more, maybe going through several more hours of fun and even impregnating her (giving us the option to give her a creampie in her pussy).
I like the Walter situation being present in the girls' mind. Keeping him lose and able to threaten them allows Jason to keep his clutches on Angela in a big way (because he is basically blackmailing her into being his cumdumpster (and even possible breeding cow) to keep Walter from Bibi) and Bibi in a basic way. Maybe have another scene before she goes off to the Bahamas where Walter is having sex with her and her mom (or maybe Bibi and Angela).
As for the next update, maybe have it when David finally arrives at Jason's house, a few things could arise. 1.) Maybe all three have left and David arrives to an empty house and goes off whining and complaining like the baby he is (just a basic option...by the way, I really hate David, so I really want nothing good to happen with him in this story). 2.) Maybe they have all left, David arrives and the boyfriends arrive with the rifle/shotgun. They hold up David, threatening him. He is smug, just like in the club scene, but the boyfriends are too "scared" and shaking, so David tries to make a move. The boyfriends are too jumpy and the gun goes off, either killing David or badly injuring him (like maybe shooting off his dick and balls). 3.) Another option would be they weren't able to escape. David knocks Jason out and he goes to rape the girls, but the boyfriends show up and kill/mortally wound David. Jason wakes up and takes the girls and escapes. 4.) Have it to where either of the two types of setups happen (boyfriends show up or Jason and girls are there). They get the upper hand of David and decide to teach him a great lesson. He is tied up in Jason's dungeon and a fucking machine with a huge dildo is fucking David's ass. He is left this way while Jason and the girls head to the Bahamas for a vacation. After a few days or so, either they arrive back at the house or Jason calls Anderson or his one blonde girl to go release David. The person that goes to release David arrives in the dungeon to find that David is still hanging there, having cum gallons of cum (a lot all over him and he has eaten a lot) and he is a babbling fool, his erection become permanent, but he cannot have an orgasm again unless someone with a massive cock is fucking his ass as well.
And of course for the girls, at least have them getting anal fucked by Jason. Then, maybe while they are down in the Bahamas, Jason as been "threatening" to breed both of them. Maybe while they are down there, because they were rushed to get out of their situation, they forgot to grab (or couldn't grab) them. They insist on having it, or they would not fuck Jason (or whomever). Jason "gets" them some, basically just placebo pills, and he starts breeding them there. Or they could have gotten them before they departed and while down there, either Jason steals them or replaces them with maybe fertilization pills and he starts to breed them. And because of the situations I mentioned above, David never gets to see any action with them.
