When you and auntie wake up naked next to each other, auntie is shocked! She realizes you two had a little too much fun partying last night and ended up fucking. She starts to become really worried about how your mom will react, and there's no way to sneak out of the room without getting caught. But she remembers one of her voodoo friends gave her a shrinking potion a while back. She doesn't really believe in it but it's worth a try! Before she goes to get the potion tho, she wants to have your cock one last time! After you fuck her on her back, she tries the potion... it works! She's amazed at your new size, and is turned on by the fact that she'll be able to keep you with her all the time without anyone knowing. She sees your tiny boner and realizes you must love seeing her as a giant now. She says you should masturbate together, then the has you climb inside her pussy and wiggle around til she cums. She licks all her pussy juices off you and teases that she's going to eat you, but all she really wants is to keep you as her tiny lover!
