Before & After: Step-Mom Surge [BE/Amazon] (Patreon)

I couldn't quite decide which version I liked best, what do you think?

=======

Before Panel: A step-mom, neglected and left at home discovers a new yoga class (with a new supplement included in the membership). When she finally works up the courage to go, her husband tells her to bring his son along as a joke.

After Panel: When the husband comes home, he discovers that not only has his housewife grown huge, but his son as well. The husband can't quite figure out what is happening, but their knowing smirks make him nervous. And there's a yoga retreat coming up soon?
