His raging hard on

"You are in no condition to go home to my sister with a raging hard on and pre-cum on your pants, now, are you?", Tammy cooed.

John stood up in horror, his cock pushing against the fabric of his pants and a wet spot betraying his lust for his wife's sister. "What? Oh! Well that's not what you think...." he stammered.

"Shhh....". Tammy said as she gracefully stood and covered his mouth with her own. Her tongue darted into his mouth as she rubbed his stiffness through his pants. Deftly, she quickly undid his belt and pulled his pants and underwear to his knees reveling a cock slick with pre cum.

Before he could resist, she dropped to her knees and slid his slick cock into her warm, wet mouth. Tammy slowly moved her head up and down on his cock, teasingly grazing the underside of his shaft with her tongue.

Reaching under her dress, she pushed three fingers deep into her wet pussy. She greedily fucked his cock with her mouth while devilishly plunging her fingers inside of herself. Her moans caused a pleasurable sensation on his shaft. He looked down to see her ass writhing on her fingers. Her other hand pushed down the top of her dress enough for her round tits to spill forth for him to view.

John groaned in pleasure, as he reached down to grab two handfuls of her thick blonde hair. She raised her deep blue eyes to his as she plunged her mouth onto his cock. Grabbing her hair caused Tammy to moan and quicken her pace. It didn't take long for him to feel the pressure in his balls. The forbidden nature of fucking his sister in law's mouth sent him over the edge, and it took less than a minute for John to explode in Tammy's lustful mouth.

Pushing his cock deep into her throat, he pumped a thick wad of cum into her eager mouth. John's wife Taylor never let him cum in her mouth, she hated the taste of semen. However Tammy's eyes widened in delight, and she swallowed the whole load and finished by cleaning his cock with her mouth and tongue.
