Want and need swept away everything but lust. His hand found bare skin, caressed it. My nipples burned under his touch, tightened into tight buds. His...mouth left mine and my shirt found its way to the floor. Without thought, I pulled his shirt up to expose the perfect masculine chest. Muscularity isn’t masculine, although it can be a part of it. His chest was formed of skin and sinew, the muscles hard enough to flex when he pulled his shirt off the rest of the way, but it wasn’t bulging with. He could hear her moan, and catch her breath, and as he continued to press forward, not harsh or rudely, just firmly steady, he could feel his shaft continue to slide inwards, pressing into her warm back channel. She was so tight, he felt like the blood was going to be cut off to his prick, but he kept on. Inch by inch, he watched his thick shaft disappear inside of his sister, until he could not see anymore, her ass brushing back against his stomach. Groaning, he held himself still for a long. “I’m not angry,” she tells him gently.Far lifts his head so he can look down at her, his eyes a little crazed, a lot hopeful. “Mom...”Damn it. He wants me. The girl swallows. “What’s going on with you?”He bends a bit, resting his forehead against the top of her head. He seems so comfortable that Rory has to assume he does this all the time in the future. “Oh fuck, Mom,” he says gruffly. “I love you so much.”This is so strange for Rory. But it is also nice and fuzzy. “Okay...” She can’t really. The evening was an orgasmic delight for the young woman, but she knew she was also there to learn and learn she did. She observed how the older woman had broached the subject of sex so innocently, had aroused her desires without her even being aware and charmed and flattered her into an initial kiss, embrace, fondling, stripping and finally the ultimate, secret, unspoken desire of all women, though few would admit it -- to be made love to by another woman. As their bodies entwined and writhed.
