Did you think Matsuyo can do to Osomatsu belly rubs? he can come like "mommy my belly hurts :(" and she will be like "ok honey come with mommy" and the she started with the rubs
I donโt know how to answer this without it getting... weird... But Matsuyo is much more likely to slice Osomatsu into ribbons with her traps if she catches him trying to raid the pantry anyway, haha.
(This was what happened when the boys tried to sneakily eat all of the Top Ramen in the house)
