Update in 2021:
This series was what was cited when my hosting privileges were revoked by my old host. As such, I’ve decided not to include the full series on this site anymore. If you want to see the rest of the pics, you can find them in this gallery here: https://www.erofus.com/comics/glassfish-comics/exercise-mom or just by searching around the internet, I’m sure.
My good friend Glassfish has a series of pics she’s doing featuring a busty mother helping her young son get into shape, by any means necessary. If that doesn’t explain the premise of these images for you, then perhaps the alternative title of “Sexercise” will. Either way, these are the colors I’ve done for the series so far, with more on the way as I complete them.
If you like Glassfish’s style (and really, how can you not), please check out her own sexy blog, The Glassfish Bowl. Cheers.
