You thought about it: you could do sex with a very sexy lady but the one who will feel it is a 5 year old. You were thinking so much until Lui said "Well, have you thought about it yet?" while sitting on the couch and playing with his breasts. Finally, you agreed to Lui and Lui starts to get excited about what is the thing you want to do with him. "But first, make a wish that you don't get pregnant", you said. Without hesitation he wished for that and you took the ring of his hands. You felt those beautiful hands of Cassie but you still remembered that Lui is in this body. You had an devious grin as you knew that Lui will definitely help you with it. You said "Ok, Lui. The thing we're going to do is called sex and it is very fun". Lui doesn't understand the word 'sex' but when heard fun, he can't wait for what's happening as he was excited. You and Lui in his very hot body went to your bedroom as you have a very big smile on your face. "Wow, you look very happy for this thing" said Lui. "Well, this is my first time doing it, so I'm very excited", you said happily. Both of you are in your bedroom and you closed the door. "Now we need to take off our shirts and pants" you said. Lui took off his shirt and pants revealing the Cassie's body which is very sexy. Your mouth started to water as you see this gorgeous body of hers. "Should I take of this black thing that holds my jiggly things?" said Lui. "That's called a bra and we remove it during the thing. By the way, those jiggly things are called boobs", you said.
