Tammy kisses him passionately

Tammy arched her head, her lips finding John's. First she kissed him softly, then her tongue began exploring, while her ass pressed back into his crotch.

John placed the glasses on the counter, and placed his hands on her slim waist, grinding into her ass as Tammy moaned in his mouth. Tammy was overcome with desire, devouring John with her tongue and lips, rocking her ass back into his hard member... only two thin pieces of fabric keeping them apart.

As he made out with her, John reached down and pulled her tight leopard print mini dress up over her hips. His dick sprung free from his boxers, and he lost himself in the feeling of their skin contact. His cock felt hot on her ass, like a hot knife touching butter. A small thong protected her taboo entrance.

Between moans and kisses, Tammy said "John, we can't... Taylor is my sister... Ohhhh!"

Her words were cut off as he pulled her thong aside with one hand, and sank a finger deep into her wetness. She too was like a furnace, the hotness of her pussy declaring her need to be fucked.

John continued to kiss and finger her as he slowly rubbed his cock on her ass in a sawing motion, her hips rocking on his finger like a hungry nymphomaniac. Her tongue explored his mouth in rhythm to his thrusts.

"Uhhhhh!", she moaned, "This is wrong. We shouldn't... Deeper! Use two fingers!"

John grinned at her double talk, the thought of fucking his sister in law was mind numbing. And to see such a normally powerful woman melt in his arms was intoxicating.
