I saw a number of posts yesterday lamenting the cliffhanger.
That wasn't a cliffhanger. It would have been a cliffhanger, if MC was taking turns with Cat and Sophia, shouts "I'm cumming!", and they end the chapter keeping which girl he was inside at the moment hidden. I like how they all fell asleep for the end of the chapter. It was sweet, and leaves a good opportunity for him to wake in the middle of the night, and partake of any of the 3 women in the house at the beginning of the next chapter. I'm still hoping for Aunt Liz to be his first for getting family in the family way. I can see my own story for it already. MC wakes needing to pee. He slips out of bed not waking the girls, and heads to the bathroom. He returns to the bed to find Cat and Sophia cuddled up together, and refusing to part so he can't get back in with them. The only other place for him to go is Aunt Liz's room. Sleep sex is supposed to be a thing in this game, so why not have Liz take advantage of him while they're both asleep, and she's dreaming of him. They could wake with him still inside of her, have the initial freak out, and then think maybe it wouldn't be so bad. From there, they could really go at it, and bring baby number 3 into the game.
