Taken Up the Elevator 1 does not need to be read first. It is a prequel that tells the story of how Brad and Meg came to leave Earth, which is covered in the prologue of The Swinger’s Guide. So really, the only reason to read Taken up the Elevator 1 is for the sex.
However, if you wish to read them in order, this is it:
Taken Up the Elevator
1
The Swinger’s Guide to
the Galactic Gangbang
Taken Up the Elevator
2
The Oral Oracle (To be
released in Oct. 2018)
The Swinger’s Guide to
the Galactic Gangbang Book 2 (Yet to be published)
Taken Up the Elevator

Have fun and play safe!
