She is an 18 year old stepdaughter!
*****
Sam makes sure his wife is washing the dishes in the kitchen, occupied completely by her task, before he corners his stepdaughter Susan in the hallway and leans in close to her ear, kissing her neck and feeling her shiver beneath his touch.
"I want to see your pretty pussy humping your cute pillows when I come in tonight, hm?" Susan blushes a bright pink but nods, her teeth coming out to bite down on her lip. Sam slides a hand down her pants and gently touches the soft, smooth pussy of his stepdaughter, feeling her twitch and her hips start to grind upwards for more. His fingers dip down, listening to her gasp, and he smiles at the wetness already coating her slick entrance.
"Bad girl. Have you thinking about my cock all this time? I'll take care of you tonight, baby. I want to see your naked pussy drenched and humping your poor clit against that pillow when I come in, okay?"
"Yes, daddy," Susan says shyly, and with a cute peck to his cheek she turns and disappears into her room, her long hair whirling behind her.
Susan had been such a tease lately, ever since Sam had "helped her out" after catching her playing with her pussy late at night. His stepdaughter had been walking around "forgetting" to wear her typical shorts, allowing him to get eyefuls of her plump, round ass jiggling in her tight panties as she strolls around the house. Or when she'd bend over in front of him in her cute little skirt, letting him see the dangerously sheer panties she was wearing, outlining the prominent puffy mound of her perfect pink pussy. His cock started to twitch as he remembered the feeling of her slick pussy lips grinding hungrily up and down his cock and he sighs. He couldn't wait for tonight.
Sam made sure his wife was asleep before quietly standing up and sneaking to Susan's room, his cock already hardening. He stands at the doorstep for a while, pressing his ear to his girl's door, and he smiles as he hears desperate little whines coming through the door. His mouth waters as he opens the unlocked door to feast on the sight in front of him.
His pretty little stepdaughter was straddling a fluffy pink pillow, her long smooth legs shaking on either side of it as she rolled her hips down onto it. Her back was facing him as she grinded what must be a sore, puffy pussy against her pillow. Her back was arched, giving him a glint of her pussy whenever she pulled away from the pillow: it was glistening and dripping, her pussy lips twitching and pink, contracting around nothing like it was already begging for her daddy to slide his cock right into her tight willing wetness.
She doesn't stop even as she hears her daddy stepping closer to her. She whines instead, looking over her shoulder to look at him with wide, pleading eyes.
"Such a good girl for me," Sam cooes, running his hands over her moving body. Her skin was warm, almost hot to the touch, and she moans softly at his hand on her. His hand slowly trails to her thighs. He smooths the tip of his finger over her wet, dripping slit.
"You want my fingers in your pussy?"
"Yes, daddy," Susan moans, "please finger my wet pussy - it's so wet for you."
How could he say no to his little girl? Sam slides two thick fingers into her tight warm wetness, causing the lithe girl to arch up and moan, her pussy dripping another pearly strand of wetness onto the bedsheets beneath her. He fingers her slowly, his fingers curling upwards skillfully to rub against her gspot.
"Ngh, daddy, I want to feel your cock in me.."
Sam raises an eyebrow, continue to play with his stepdaughter's wet pussy.
"Oh? Going a bit fast, no?"
"I've been thinking about it all day," Susan whines.
"Yeah? What did you do?" Sam speeds up his fingering, feeling the wet, tight flesh of Susan's pussy tightening around his thick fingers.
"I touched myself this morning. I played with my clit until I was swollen and dripping, and then.."
Sam slows his movements, making her mewl and shake her ass with a twitch, begging for more.
"And then what?"
"I-I fingered myself, daddy, I thought about sucking your thick cock and- and I thought about you fucking my pussy.."
Sam's breaths were laboured. His cock was so hard it felt painful and he unzipped his pants to take it out, stroking it gently as he listened to his stepdaughter.
