I can see not fucking Kelly anymore out of loyalty to his sister, but they've already broken the incest taboo.
A story this great deserves more parts. Definitely not where I would have taken it.
In this part and future parts I'd have had both girls end up pregnant and the brother moving in... Maybe even kelly's mother finding out and joining them, then eventually also getting pregnant. :-)
Maybe it could even use some light bondage or other fetish (well probably not something like scat, eww).
This is a good story, but add more dialogue as the girls moan and beg... don't just say "they begged for more cock," have them say it. Makes things much more interesting and hot.
