Dinner was ready; Dave's wife, Jenny, had sent him upstairs to fetch their daughter Sarah and her boyfriend Jake. Sarah had been dating Jake for over a year now; they'd met at college and instantly fell in love. Both were eighteen and their parents trusted them to be mature and responsible; they were in Sarah's room, studying for their final exams.
The door was closed, all was quiet, so he knocked softly on the door, not wanting to startle them. He heard Sarah say "Come in." so he pushed the door open. Dave stopped. Pinned to the wall, the girl he had brought up for thirteen years was naked and wrapped around her tanned boyfriend as he thrust into her. Her eyes were screwed tight, lips forced into a thin pale line as his cheeks clenched and her thighs gripped his waist.
Dave looked on, frozen, helpless, too embarrassed to say anything as his cock responded to the live porn show in front of him, tenting his sweat pants. Sarah came down from her orgasm; head dropping, eyes opening but unable to focus on the man in the doorway who backed out slowly and quietly closed the door.
"Dave!" Jenny shouted from downstairs, "Are they ready? Dinner's on the table."
"Just a sec love." Dave shouted back, "Just been to the loo." He heard scrambling from his daughter's bedroom as they rushed to dress. He knocked on the door, a little louder than before.
"Won't be long Dad." Sarah sounded out of breath, "We're just tidying up our notes."
Without opening the door, Dave said "Okay." and went back downstairs.
During dinner, Dave looked across the table at his daughter; she gave no indication that she'd seen him; no awkward looks or blushes. She'd seen him accidentally in the bath when she was twelve; only his top half, from his chest upwards; but she'd blushed for a week whenever their eyes met. Now though, it seemed like this was just his little secret with himself.
After dinner, they watched TV for a while, Jake stealing furtive glances at Sarah. Jake went home, kissing Sarah at the door as he left. Her cheeks flushed as she turned around and saw her father standing in the hallway. "Serious then?" he joked. "Do I need to buy your Mother a hat?"
"Dad?" She replied, embarrassed, "We've only been seeing each other eighteen months, I don't think we're quite ready for that."
"A year and half? Already? Well I never." Dave said. "We haven't met his parents yet."
"I have. They're nice, but I think Jake thinks that you won't approve of them."
"We're not that bad, are we?"
"Well..." Sarah bit her bottom lip, "They are a little... Unconventional."
"Ahh." Dave nodded, "Unconventional. Are they both little people?"
"No!" Sarah laughed, "They're normal; just not what you'd expect."
"Well that's settled then." Dave clapped his hands together. "My interest is piqued; you invite them here for dinner next Saturday and we'll see just how unconventional these freaks are." Sarah punched her dad's shoulder then hugged him before going upstairs to her room.
"We'll see." She said as she dashed upstairs. Jenny was feeling friskier than usual tonight. Her hands wandered over Dave's body until she found his semi-erect penis. He'd been thinking about Sarah; the way her face scrunched as she came, Jake's cock thrusting into her, pursing her lips in a silent scream whilst her lover took her to the edge. He didn't know what Jenny was thinking as she slipped beneath the covers and took him in her mouth.
Fully erect, Dave turned onto his back as Jenny climbed on top. She kissed him, tongue darting into his mouth as she lined herself up and impaled her slick pussy on his raging hardon. He'd never known her to be this wet before, or, for that matter, this horny. Head back, gasping for air, she grabbed handfuls of chest hair as she rode him through her second and third climaxes, falling forwards, breathless as she felt him swell; his cock falling from her as semen gushed over her buttocks and between her legs.
They lay together, kissing, regaining their strength. Dave hugged her tightly and kissed the tip of her nose. "Wow! What's gotten into you?"
"Just a bit horny love." Jenny replied. "Watching those two all lovey-dovey together reminded me how much I love you." They kissed again; Jenny rolled off the bed and walked out of the bedroom. She absently wiped the cum from her buttock and licked her finger, savouring his saltiness as the bathroom door swung shut.
Dave sat up in bed, bed springs squeaked softly from his daughter's room, followed by a breathless gasp. His mind wandered back to this evening's scene; she looked so much like her mother, especially in the throes of passion. He'd never met or seen Sarah's father; he'd disappeared before Sarah turned five. Jenny met Dave eight months later at a work event and they'd been inseparable since.
