Taken & Cuckolded by My Big Black Coworker. My Big Black Coworker, #3

Since that fateful night, Daniel's workplace bully has actually been nice to him. That is until Al tells him that he wants to take his wife in front of him. Tempted by the offer to help him "get him" a woman he has a crush on work, Daniel agrees to the man's insidious plan. But on that new and fateful night, the double-cross is in and Daniel finds himself helpless to interfere, as his wife deliberately takes on his bully, doing things with him that she had never done with Daniel.
And the weak husband is both repulsed and extremely turned on. The Big Black Coworker saga take another unexpected turn, and not everything is as it seems. But if you read through it all the way to the end, you'll find more than enough twists and turns to satisfy your effort.
