Stagger - Obsidian Mechanics, #4

Sierra had just finished a long field trip in Egypt with her P.hD. students and was looking forward to getting home and back to normalcy. Her nephew, Atlas, was due to have his baby any day and she couldn't wait to lavish the little one with love. Stagger and Helios had been joined at the hip since they were twelve years old and they first learned they were becoming step brothers. Where a lot of blended families struggled, Stagger and Helios got along like a house on fire.
There wasn't anything they wouldn't do for each other. They never realized that their relationship came with an even deeper meaning. They were fated.  This is a Reverse Harem with MM scenes. Subjects and language suited to 18+
