The stranger's licking his hand.

The stranger ran his wet tongue over his hand before leaning forward and reaching between Hannah's legs. His cock was in my wife's ass, and now his fingers were on her clit. "Yes. Rub my pussy you nasty fucker." The stranger's hand moved quickly, as he leaned his body and the length of his cock all the way into Hannah's tight ass. All the way in he jerked spasmodically, making short rough stabs into her. He was grunting, and soon I heard my wife cry out, "I'm going to fucking cum!" She bit her lip nearly hard enough to draw blood and her eyes rolled back into her head as her pussy juices gushed over the stranger's balls. He continued his short rhythmic thrusting as Hannah shook in ecstasy, but soon his grunting became shorter in breath, louder, more animalistic. He withdrew his big cock slowly from my wife's ass and shot long arcing spurts of cum all over the her back, staining her clothes.

"damn," the stranger stammered, panting, "maybe I won't charge you for that product after all," he told her as he dismounted her, knocking her off balance and onto the dirt in a crumpled state. She got up, smiling at him, and gathered her clothes back into a presentable state of dress, though she didn't clean the cum up off her clothes.

My wife laughed, sounding elated, as if she'd achieved a soaring high from the ass-fucking she'd received. She told the man, "You can keep the pictures. Show a couple friends. Maybe we can find a better way than money to pay for my next bag." My cock had already regenerated into a full raging hard-on again, but I was regaining my senses. I tucked my dick back into my pants, barely concealed in my impractical leg-wear, and limped back to my car before Hannah left the man with the van and spotted me in the bushes. I sat for a moment and tried to get my head straight. I was emotionally bruised, but sexually entranced. I didn't have a chance. I saw Hannah leaving minutes later, and checked the clock. Hannah was supposedly still "in class" for several hours yet. I decided to see where else she might go.
