Now let me hear you finger yourself!

Just thinking about the possibilities were making jack so horny. Unfortunately there were no chicks to try it out on... except his 18 year old sister Kelly.

So anxiously, he shouted "Now let me hear you finger yourself!" The music was then turned off. And was followed by a pause. Jack was thinking he was busted and he was never gonna be able to look his sister in the face again when he heard a faint groan.

he pressed his ear against the door to examine this sudden interruption if inevitable devastation. Sure enough she was masturbating on demand for him. His ear was not the only thing pressing against the door now, as his hard-on grew bigger and bigger.

He was so excited yet still so on edge about the whole situation. He just needed one more bit of proof!
