He was still asleep, at least halfway so, slowly drifting back to an awareness of the morning sun filtered through the closed blinds, illuminating the room with the soft warm glow of the day. Gradually his consciousness sharpened to the awareness of an intense, yet strangely soft feeling of wetness and motion on his nipples which were straining against, or perhaps towards, the touch of a wet tongue and lips teasing them and sending a direct current of sexual electricity to the energy center--some interior space that pulsed just behind his cock and pulsed slowly with a growing sense of desire and unfulfillment. This energy started to flow into and through his cock, which starting it to participate, in a twitching sort of motion, in its own awakening. It was as if his cock was aware of the intense pleasure being provided to his nipples and, jealous of them, attempted to match their straining desire towards that source of the deliciously intoxicating wetness above would notice its pleas for similar gifts.
His eyes opened slowly and sought to focus on the apparent source of all this exotic sensation. At first, he could see only a tangled mass of luxurious dark, almost black, hair which he recognized as Amanda's. Her head bobbed quickly from one side of his chest to the other as her tongue flicked, teased and, swirled around the tips of his nipples. Her teeth would gently grab each nipple in turn and she raised her head just a bit to tug at them. They had often talked about and compared this wonderful trait of their nipples having some kind of direct connection to their sex. It was almost as though they had two extra cocks/clits to share and play with during the delicious tension of sexual arousal.
Now he was fully awake and moaning softly. He fumbled clumsily in an attempt to extricate his arms from beneath the covers in order to reach over Amanda's back--she had her head lying across his torso, with her back to him--and cradle her soft and voluptuous breasts which he knew would have their own dark brown centers of pleasure waiting. Amanda's nipples were also a complete turn-on for him, jutting out almost a half-inch from the aureole when she was turned on. She had to be circumspect about wearing cotton tank tops and other tight-fitting clothes because if she happened to get excited (or if the weather turned cold!) it was quite obvious, and somewhat embarrassing for her state of excitement to be broadcast so directly. Something they had used to heighten their own pleasure out in public from time to time.
