She just looked at me, and i guess i came in at the end of the show, and she just closed her eyes, arched her back and let out a loud moan of pleasure...as she came. I stood there and stared at her in shock, not being able to move my eyes or my legs( my dick was having no trouble moving). She opened her eyes again looked at me as her face paled as she covered herself with her sheets. I snapped back to reality when i heard a car pull into our driveway. Mom and Dad were back, as I realised where I. It was a sobering vision knowing what must go on in here but the naughty curious side of me could not help but wonder what it would be like under the hand of someone like the Chief. After a few minutes he suggested that a demonstration might be in order and maybe I should lay down on one of the benches and he would secure me into position so I could fully understand what it would be like to be at his mercy. The Idea made me blush, which did not go unnoticed, and also made me tingle in between. He’d never dare mention any of his thoughts to his wife; she would never understand his deep desire to see her being fucked by a black man.

The 'derailleur' pushed or pulled the chain by means of a cable attached at one end to a shifter on the handlebar and the other end to the derailleur.So that the crankset was not continuously turning, a freewheel mechanism, stolen from one of the Salvation Army Thrift Store bikes was incorporated in the rear wheel. When the rider applied pressure to the chain by means of a pair of foot cranks with a sprocket the freewheel device engaged. Without pressure the freewheel freewheeled, rotated.
