Ryuki sat on the couch to Yui's left, their thighs touching. They had been watching TV, but now he was more interested in other pursuits. He looked down at the way her thin pajama top lay across her breasts. It was a soft cotton fabric, with camisole straps and lace around the low v-neck. Her hands were nestled together in her lap. He put his right arm around her shoulders, reaching his hand down so that his fingers lightly grazed her right nipple through the thin cotton. She jumped.
"Hold still," he purred into her ear, and placed his left hand in her lap, enclosing both her hands in his. He brushed his right index finger across her nipple, lightly, maddeningly, back and forth, back and forth. Her nipple was hardening under his touch. He kept the pressure of his finger gentle, but continued a steady stimulation of her sensitive nerve endings.
