I would, but I've got my own stuff I'm trying to write in my spare time.
However, I would suggest plenty of licking, fingering, and figure MrsWalker's got a toy or two somewhere to break out. And that since oral anal was already included, there would need to be lesbian anal too, atleast fingering or toying if not more oral.
Or, MrWalker could come home, catch them in the act, & join in.
