While the ballon was full Jim said "controll her inhibitions" and slowly let the air out.
Brandy still having her erotic dream started to show signs of the change. She started to rub her pussy in her sleep slowly at first, but gaining speed as the balloon let out air. Inside her mind her dream was going from erotic to her having sex and then to all out kinky sex fest. The balloon was only half empty when she woke with a jump after orgasming. She didnt even notice her change yet as she just wanted something hard and long to pleasure herself more. She wanted a dildo, but as she wasnt normaly such a dirty girl she didnt have one, but as she got hornier from not getting more of a release, and the balloon let out more air her mind started to think of much dirtier ways of solving this. As the balloon finished, Brandy's inhibitions were so low she was highly considering going into her brother's room to ask him for some "help" in solving this problem.
(I just fixed the previous chapter cus whoever did it left out a bit and it made no sense, hopefuly this is what he intended and no one gets pissy. Im too lazy to add all the sugestions though feel free to go back onee to get more suggestion for next)
