"Woah, big brother? I think you got got bigger just like me." Timmy smirked.
"Ungh! Come help me now." Jamie said.
Jamie's shaft grew and inflated, which made Timmy's member look tiny. Jamie developed a horny look in his face.
"Ouhhh, come, ungh, here Timmy."
Timmy was helpless to disobey. He began stroking the 15 inch hard-on very meticulously.
"Dont you wimp out now!" Jamie sneered. He shoved his cock right into Timmy's face.
"Yea, be a good little bro"
