Chapter 8: Hailey's night

Having returned home, Leon finds himself eye in eye with Hailey the very same night. The youngest female bodybuilder has won the bet with her sister and will have Leon first. 
It's going to be a very intense night and Hailey will show Leon all corners of the room. She lifts him easily with one hand and throws him around, teasing him and making him mad but telling him not to come. Hailey even imitates some of the pictures she's seen on Leon's computer - only, she's bigger than the girls from his pictures! She's bigger than she or he ever dreamed! And so Hailey takes Leon. Again. And again. And again...

In the morning Hailey reports to Hannah during a beach run, and Leon visits his old friend Beth. She's changed a bit, and Leon discovers he still has feelings for her. But before he knows it, it's night again, and there's another big girl waiting impatiently for her turn...

This chapter features an incredible, long NSFW scene between Hailey and Leon. There's all kinds of lifts, delicious domintion, comparisons, throwing, big boobs, high heels, and everything you ever wanted... Go drink it up!


Muscles in the Family is a long female muscle growth series that tells the story of two girls who want to get bigger for one boy. Hannah and Hailey, starting out at thirteen and twelve years old respectively, have a crush on Leon. Leon is from a different mom and dad, but they have been living together ever since Hannah and Hailey's mom got together with Leon's dad. For all practical purposes, they're siblings.

Very hot and sexy content. Now that Beth is growing, I’d really like to see more height comparisons to see how much she’s grown.

It has already been said. This series is my absolute favourite on this site and, in my opionion, one of the best in this site: it's very well written and amazingly rendered. You'll dream about having stepsisters like Hanna and Hailey: they're beautiful, confident and dominant. Their personality evolves deeply through the series together with their bodies. I sincerely suggest reading it in order as I did because every chapter is worth it. If you lovemental domination, height comparison, and the sister-brother relationship you can't miss this.

Those two amazons are going to use Leon up. They might even kill him or at least put him in some hospital with a case of extreme exhaustion. He is a goner I fear. The girls sexual appetites are just too huge for poor little Leon to satisfy.

First, I don't agree with the other comments that it is the best story. The artwork is fantastic. The two goddesses are incredible. The story in itself is only a pure obsession of dominance. This entire chapter is redundant. I feel that the story is stretched out to make more épisodes (chapters).

Whoa, whoa, whoa! I'd been waiting all week for this one, and even then it exceeds all expectations! H and H completely OWN their brother, what a lucky guy! The whole scene of Hailey taking him over and over again is pure bliss. I wonder what they will do about the Beth situation, and I wouldn't mind a comparison of Beth's puny muscles with the two goddesses. It cannot be easy for their stepdad to have two goddesses walking around his house. God I just love reading about them so much, I hope that we get more casual family situations in the future! This series is just so, so, so perfect!
