Amadahy has been spending the summer at her gramps’ place because he has a really nice pool. Edyn has arrived early for a pool party they are planning, and Amadahy has a big big secret she wants to tell her. Amadahy’s gramps’ computer broke a little while back and he gave it to her to fix. On it she discovered a whole bunch of Brat Princess videos. Now that Amadahy knows her grandpa has fetishes, she’s worried he’s going to be creepy around all the hot Princesses at the pool party. The only solution, as Amadahy sees it, is to get gramps into chastity. Amadahy calls for her grandfather. She screams at him for not cleaning her room well enough and slaps the old man in the face, before telling him to kiss her girlfriend’s boots. Amadahy makes her grandpa take off Edyn’s boots and ask to kiss her feet. Edyn allows Amadahy’s grandfather to kiss her feet. Grandpa seems to enjoy the foot worship, which is creepy to the Princesses. Old men are vulnerable and easy to use, and in that respect good for a Princess to keep around, but they don’t’ want to see grandpa getting off on hot young women because that’s creepy. The sooner they get gramps into chastity, the better. In a few hours, a big group of sexy 20 somethings will be filling gramps’ awesome newly renovated pool, and he can’t be creeping on the young women! An old man creeping around the party with an erection would be an embarrassment to the party hostesses. Amadahy tells her grandpa that she is just going to put him into chastity for the day, and that after the party she will let him right out. She very forcefully makes her grandpa worship her feet. She fucks grandpa’s face with her foot because he is nothing but his granddaughter’s bitch. Amadahy makes her grandfather go into the bathroom and lock himself into chastity. After the device has been locked, she wants him to emerge naked and give her the key. Once Amadahy has the key, she reveals to her grandpa that she has no intention of letting him out after the party. Amadahy and Edyn laugh as they spit in the old man’s pathetic face. Grandpa is ordered to have all the food and drinks ready for the party and is not allowed to wear clothes when the guests arrive, so that the female guests can feel safe that he is in chastity and be assured that he cannot get an erection in their presence.
