Sarah has always known that I would love to watch her with another man but has just been a fantasy. Now it seems like it is going to happen. She had o...viously had enough to drink and was very excited, why she wouldn’t be, here was Darren 26 year African American who wants to fuck her.“Well” she said as she raised her knees and opened her legs, “I’m ready.”Darren and I just looked at each other and then as quick as possible got naked, he was in very good shape and his cock was a good 9 inches. Um...”“Ass?” she filled in for me. “You can say it, can’t you?”I met her eyes and chose instead, “Butt.”She shook her head. “No. Say it. ‘A slap on the ass.’ Say those words.”I gritted my teeth. “A slap on the ... ass.”“Now say it all together like it’s supposed to be,” she said, sounding like she was more recovered than her gait suggested.I sighed. “A slap on the ass.”“There you go,” she said with a nod. “So, you’re not into pain. Is there anything you strictly will not do?”“Whips,” I said. He started moving his head down my body in search of something it appeared. Max kept on sniffing as he waived his snout around my thighs now. To me it just seemed like his usual sniffing around, so I didn't see the harm in letting him explore whatever scent he was picking up while I continued to pet his soft round belly. I suddenly became startled when I felt his snout on my crotch area since he had caught me off guard and I questioned him in alarm saying, "Whoa boy?! What are you doing?...". Then he heard his mother moan softly and turn in her sleep. As she did, the sheet covering her slipped down exposing one of her mountainous breasts. His cock abruptly stood at attention as he stared down at the big pink melon with its rose-colored cap.Then something inside of him snapped. There was no way he could stop himself now. Their fate was sealed.Taking a deep, shuddering breath, he stole over to the couch. As he did, his aching cock jutted out defiantly eager for conquest.As his knees.
