Lillian is curious about the bump in her adult baby friend's diaper. She doesn't have a big bulge like that so she undoes his diaper and takes a look. She finds a big stiffy and then she compares with watch inside her diaper . She doesn't have a stiffy but she has a hole.

She figures it would be really naughty but what if they put his stiffy in her hole? Her hole was starting to get tingly and wet already at the thought but she didn't know why. When she put it in she sure found out! They both did big cummies.
