"How about I call Karen over to hang with us little bro?" Andy asked.
"Please no" Jesse begged. At this point Karen would probably mistake Andy for himself due to their apparent swap in ages and masculinity.
"Too bad" Andy said as he went to Jesse's room and grabbed his cell phone to call Karen.
Jesse followed Andy and tried to stop him. However Andy's taller stature meant Andy could just hold the phone over Jesse's reach. Jesse was too weak to force his brother to stop what he was doing.
"Hi Karen, it's Jesse. Wanna come to my place and swim with my little brother? ... Okay perfect, come over now" Andy said as he hung up. Karen didn't even notice a different in voice.
"Okay lil bro, my girl Karen is coming over. Be a good boy and swim with us." Andy said, assuming Jesse's role.
"Hell no!" Jesse replied. "I'm gonna tell her what you did to me!"
"Have fun trying little bro!" Andy said and he forced Jesse outside with him before locking the door behind him. Andy held the house key in front of Jesse's face before hiding it under a large rock.
"We're going back inside when I say so little bro. You get to show Karen your cute speedo and try to convince her that you are an 18 year old man." Andy laughed. Jesse ran over and tried to lift the rock, but it didn't even budge due to Jesse's weaker body.
"She should be over aaaany minute" Andy said.
