"I see what you mean," you gasp as Serena devours your cock. "A tigress indeed. Mmmmmm, that's very good girl! Very good!"

Brian grins and crouches behind her, his hands sliding around and unbuttoning her shirt. Serena squirms as he undressed her, but didn't pause as she slurped and sucked on your cock. She moaned happily as he fondled her, looking up at you with wide eyes, her mouth full of your thick meat.

She was quivering with excitement, obviously loving the hot taste of the cock in her mouth, and relishing Brian's strong hands as he stripped her shirt and bra off, exposing her breasts. He cupped them, pinching the nipples and nuzzling the back of her neck as she kept sucking hungrily, her head starting to bob as she swirled her tongue around the tip.

"That's very good!" you growl. "Your technique could use work but full marks for enthusiasm! You like this don't you, girl! Do you imagine that it's your Daddy's cock in your mouth? Are those the kinds of fantasies you have?"

You see the excited confusion in her face as she looks up at you, moaning around your cock, looking up as she shivered in Brian's hands. You realise that her Daddy fantasies might be something she's just discovered about herself, spurred by the difference in your age, and perhaps even bearing a resemblance to her father.

Serena's eyes were wide, her excitement obviously heightened at your implication that she was fantasizing about her own father, but she didn't slow down. If anything she was even more ravenous than before.

"I just... I just want your dick!" she gasped, pulling herself off your cock for a moment and looking up at you with a slight bit of confusion and doubt mixed with raw arousal. She started to work on the sides of your cock, tilting her head so that she could run her lips along it, kissing and licking upward from the base of your shaft and then back down again. You smile down at her as she works his shaft, and you see her tremble with excitement, using her, using her saliva to lube her slender fingers.

Brian has her all but stripped, her skirt unzipped and pushed down as he explored her body, fondling and caressing. Serena whimpered in need and excited uncertainty. You doubt she's ever been with two men at once, and although her enthusiasm hasn't faltered you'd be surprised if there wasn't some anxiety mixed with her arousal.

"Such a good daughter," you growl, stroking her hair as you look down on her. "I think you're nearly ready for Daddy's cock."

Serena whimpers, quivering with excitement, the intensity of her feelings flushing her pale skin as she strokes and sucks at your cock.
