The fat, mushroom-shaped head wriggled into the pouting lips of her wet cunt, stretching the slit for the invasion of his shaft. Trisha bit her lip and started to sit on his dick. She gasped as the inches of his cock slid up her hole. Ralph's stiff, throbbing prick was so much bigger and felt so much better than her finger.

Now half of his cock was pulsing inside her slippery pussy. Trisha felt her cunt muscles work around his prick and moaned wantonly with her pleasure. She was finally fucking a man, and it didn't hurt at all. It felt very, very good to have her pussy filled by a long, hard dick like her brother's.

"Go ahead, Sis, it's not going to bite you." Ralph hotly began to hump and buck his hips off the bed, fucking his cock up Trisha's wet cunt. "You've got the tightest little pussy I've ever had. Sit on it all the way now. Take all of my cock up your cunt!"

Trisha whimpered loudly as she felt his prick moving in her snatch with the rhythm of his humping. Finally she lowered herself all the way on top of him, gasping and whining in shameless ecstasy as she felt every inch of his cock bore into her juicing pussy.

I've got it all now, she thought hornily. All of Ralph's big dick, all the way up my cunt… oh, Jesus, it's good… never thought it would be like this… God, I can feel his prick throbbing and everything… want more of it… want him to fuck me now… his cock, in and out of my pussy, fucking me… fuck my cunt, make me cum…

"You like that, Sis?" Ralph panted. He dug his fingers into the quivering cheeks of her shapely little ass, holding her on top of him as he thrust his cock through the sucking, buttery wetness of her cunt. "How's it feel getting fucked for the first time?"

"Unnngggghhhh," Trisha moaned. Her cheeks flushed hornily with desire. She bit her lip and winced every time Ralph pumped his cock up her pussy. "AAhhhhh, Ralph… unhhhh… it's, it's… unhhhhhhhhh."
