"I want to fuck you now, Ralph," she purred hotly. "Please… I've been dreaming about it for so long. Don't make me wait anymore. I want to know what it feels like to have your big dick in my pussy. Then we can fuck all night! Please keep it stiff for me, Ralph!" Ralph grinned. "Don't worry, it'll stay stiff," he muttered.

"You just take off that cute little nightie and show me that fantastic body of yours. Then we can fuck as much as you want."

Trisha climbed off the bed. As fast as she could she pulled the nightie over her shoulders and flung it to the floor, leaving herself completely naked. Her big, stiff-nippled tits heaved with lust, and her hairy young cunt was as wet as a swamp. The sooner she got her brother to fuck her, the better she'd feel.

"Oh, Goddamn, Sis, I can't believe this," Ralph muttered. Staring wide-eyed at Trisha's curvaceous nakedness, he held his stiff prick and leisurely jerked himself off. "I never knew you had such a far-out body! I mean, you're the most stacked chick I've ever seen. Jesus Christ!"

Trisha giggled demurely at the compliment and climbed back onto the bed. Remembering a position her mom and dad had enjoyed fucking in, she straddled Ralph's hips, digging her knees into the bed to either side of him and positioning her dripping pussy slit over the knob of his dick.

"I… I don't really know how to do this," she stammered embarrassedly. "I mean, this is my first time."

Ralph chuckled. "Don't worry about a thing, Sis," he said, taking her hand and wrapping her fingers around his hard cock. "You just put it in yourself."

As Trisha felt the meat of her brother's prick throb in her hand, she doubted that she would have any trouble fucking him. Her cunt was wet enough to take a dick even larger than his was.

Trisha gradually lowered her cunt onto the tip of Ralph's hard-on. When she felt the spongy, cum oozing knob press into her fuck hole, she started trembling wildly all over, so excited that she was about to cum on the spot.
