8 XXX : IncestComics

this is fun smut, no rape, no preteens, just good old fashioned sibling incest.
This was amazing. This is exactly the kind of things I like seeing - no dysfunctional family dynamics, no coercion or rape, no cheating. And you can feel how close and sweet these kids are to each other. Fantastic find!
Any more from them?
Any more of this style or comic?
Lot of comics done by these two can be found on Hentai-Foundry but this isn't Incest, they are just childhood friends
Is this an original work, or is it based on something (a series, movie, etc?)
