Here are three ideas I just made up while in the shower
16. Fowl: FE Awakening Lissa and Maribelle are tasked to hunt up some food for the Shepherds and upon encountering a large flock of wild peafowl they try to hunt them, only to find their roles reversed from hunters to the hunted, Tickled on their helpless soles, pits, thighs and bellybuttons by the vengefull birds.
19. Ponytail: FE Fates Camilla, Elise and Selena are trying out a new spell that should strengthen their hair and style it in a in-season ponytail only for the spell to go awry and ending up tying them with their own now lengthen up ponytailed hair which proceeds to tickle their soles, pits and other defenseless spots until they are rescued.
28. Camping : FE three houses Manuela and Bayleth are teaching important camping knowledge much to the charging of the three houses students that are trying to have some fun horsing around competitively and believe that the 2 teachers are being sticks in the mud. They decide to teach the teachers on how to have fun by wrapping up their arms and legs in the sleeping bags and tent fabric, basting their bared body areas in honey and special herbs and letting the forest animals have a great time lickling their teachers for the rest of the day.
