Her bare breasts fall against her body as she removes her clothing. So very exposed, for him, the perfect size and shape as he trails his fingers over them, finally cupping one and then the other in his palm. Her nipples, always so sensitive, immediately respond to the stimulation. She lays on their bed and simply awaits anything he’s willing to give her. He knows how much her nipples are a weakness and that his fingertips alone are torture; a torture she’s willing to endure for as long as he’s willing to provide.
A spark, that can’t help but spread from between her legs, begins to encourage a wonderful kind of yearning. He finally takes her nipple into his mouth, suckling and teasing with his tongue. This weakness showing its true nature as her moans and trembles begin to betray her counterfeit obstinance.
