I paused briefly to ask Martin to get up on the settee and put his cock in her mouth. He climbed up and put one foot each side of her. He had to crouc... a little but Sandra opened her mouth invitingly and closed her lips around his shaft as he put his cock in. Martin moved back and forth without pushing in too far so that Sandra's lips and tongue could caress the sensitive tip. I resumed licking her slit and fingering her vagina. I guessed from the noises she made that she was having a good. My back was to the wall -in both senses of the phrase- but I wasn't ready to accept what was happening before my eyes. Even as her husky tone of voice and intoxicating perfume drove my mind in circles, I managed to stammer out a few words that I hoped would save me."M- Miss Davadis! Wh- What are you- MMF?!"She pounced. Pinning my wrists against the wall, Lucy pressed her lips against mine and slowly slid her tongue into my mouth, shocking me to the core. I couldn't react. I could only. I looked up and asked Uncle Clyde why he hadn’t fucked me…was it because he was afraid I would get pregnant? He chuckled, and said that wasn’t it, because he’d had a vasectomy a long time ago. When I held my questioning face to him, he explained that he was afraid of how I would feel about him years later, if he had gone all the way with me. I looked at him incredulously. After all the erotic things he’d shown me, why would I ever think badly of him? In fact, I went on, if he didn’t think. She reached her hands down to cradle their shafts, one in each hand, and felt their lust for her grow with every stroke of their fingers on her chest and legs. She held the stranger's cock up against her ass so she could feel him slide along her asscrack with slow steady thrusts. Her other hand fondled her husband's balls and shaft while his hands playfully cupped her breasts. "Oooh, I want you inside me," she said to no one in particular. The stranger pulled her knee up onto her.
