"Ohhhh!" Susan whispered, feeling a stab of hot pleasure in the back of her cunt. She humped forward, trying to suck his tongue inside, but he moved back slightly. "Oh! I want it! God, Mike, eat me! My pussy is on fire!"

"Wait a second, baby," Mike said. "Let me do it my way."

His way, for Susan, was pure torture. He began probing the tip of his tongue inside, curling it upward and licking across the top of her canal and over her clit, but when she was just getting to love it, he would pull back.

"Don't do this to me!" she begged. "God, if I don't get something in my pussy, I'll so crazy!"

"Don't worry, big sister," Mike said with a lustful grin. "You're gonna get all you can handle in just a few minutes."

For several agonizing moments he chewed and sucked her tiny puckered opening, before lunging the full length of his tongue inside. When he did, it was immediately engulfed in a pulling warmth. An oozing film of pussy-juice crept into the back of his throat while other streams flowed down his chin.

"Baby, you taste so fucking hot," he murmured, his voice wet with her juices, "and so fucking delicious!"

"Suck me," Susan said, her voice barely audible. "God, shove our tongue in and… eat me!"

Mike placed his hands on her hips and drew her closer. At the same time, he lunged forward, sinking his tongue deep into her pussy. His front teeth brushed her clit, causing Susan to scream out with growing hunger.

"That's it!" she wailed. "God, just like that! Don't ever, stop licking my pussy!"

Mike squeezed his hands around her body, cupping her firm rounded ass. With his middle fingers, he began diddling up and down the narrow crack of her ass for several moments before probing inside the small hole. Finally, he jammed his tongue inside with a poking motion as be jerked his fingers into her shitter. He knew he must be doing it right, because his sister stood her tiptoes and yelled out.
