I love this fic. I keep imagining Matt and Peter inviting Frank into the fort and Frank accepting because, hey, this is their space and they can at least kind of be in charge, and Matt interpreting this and coming up with 'Master doesn't want sex, might be a religious thing, might be a sexuality thing, we will likely never know but it is now our sworn and wonderful duty to cuddle him lots', because Master seems so much more at ease in a no-sex arena and like, Frank being subjected to physical but nonsexual affection a lot
