Peter had been suspicious for a while, today had given him more cause to think than any other and right at that moment his suspicions were being confirmed.
"Ahh Shit!" Peter heard her growl. There was a low grunt in reply, then the sound of soft rhythmic thumping. Peter knew the activity on the other side of the flimsy prefab door was getting more intense.
Peter had heard his daughter's door open about half an hour earlier, then shut with more care than was necessary. He had been sleepless for the last couple of days, still suffering from jetlag after his last business trip. It was now 3am, and outside the closed door Peter was listening to his daughter fuck.
He wouldn't have been entirely surprised by this alone, she was a fine young woman, 19 years old, with a knock out body and a sly, knowing grin. He knew she teased the boys at university, relentlessly, she even joked about it at home. When she was home.
What had him standing outside the door down the corridor from his own at this ungodly time of night was that Jenna was in Daniel's room, being fucked by her older brother.
Peter had seen Daniel kiss Jenna goodbye a few weeks ago, in the kitchen. He was sure he hadn't been meant to see it, but she had been standing at the sink, washing up. Daniel had been on his way out to work, and stepped up suddenly behind his sister, encircling her waist with one arm and kissing her neck almost violently. She had gasped and thrown her head back, Daniel had grinned cheekily, the same grin as his now absent mother, and incidentally his little sister, and left without a word. Peter had got the definite impression that it hadn't been the first time.
"Jenna, here..."
Peter's attention snapped back to what he was hearing, Jenna's quiet voice, unintelligible, and Daniel's murmuring reply. He heard her gasp and then the slapping of skin on skin. Long moments passed.
"Danny, Danny, I'm Cumming!"
"Shh, for Christ's sake, you'll wake Dad"
Peter smiled wryly. 'Daddy's here...' he thought
Peter had a tight pressure against the loose fabric of his pyjama pants. His hand caressed the soft hair on his naked belly and travelled down to encircle his rock hard cock. Gripping it outside his PJs he used the fabric to feel long strokes along its length. Listening to his daughter's gasps and his son's growls and the now faster thumping of body on body.
"Ugh!" His daughter's release was guttural, and primal, but restrained, tempered so as not to wake the father that was listening to the entire exchange. A moment later a similar if breathier expression from his son as Danny came.
Peter headed back to his room, shucking his pyjama bottoms off he lay down on the bed and resumed his attention on his own needs. He loved the feel of his cock, he had never been a hairy man, but the skin around his groin and lower stomach was smooth and soft. He caressed it with one hand while he gripped the hard length of his member with the other.
His attention wandered and he replayed everything he had just heard in his mind. He pictured his daughter in her favourite spot, the grass by the pool. He felt odd about thinking of her in this way, but he felt so turned on by it that he didn't stop. He pictured her sunbathing, naked. He'd seen her do it once or twice, when he was early home from work and she didn't have class that day, or was skipping it. He had always made a noise coming home, so to alert her and give her time to compose herself. He pictured her now, un-composed, warmed by the sun, one hand circling her perfect breasts in slow luxurious movements, the other between her legs, head thrown back, legs splayed, playing with herself in the open, in the sunshine.
Peter had moved both hands to his cock now, the sensations more intense, one hand travelled rhythmically up and down the length of his member, the other circled the head in short movements. Broken images were flashing through his head now, jumbled up with sounds. Jenna in the shower, wet and soapy, Jenna in bed using a vibrator, pictures playing out what he had heard through the door. Danny pounding her with strong purposeful movements. Jenna laid back on the couch, spreading her legs out. Peter imagined himself gripping the insides of her legs, shifting himself into position and entering his daughter.
He came in a burst of black stars behind his eyes.
The next morning was Saturday. Danny had left for the weekend to help his boss with market research, and Jenna wasn't up yet. Peter relaxed into the couch and switched on the TV, mindless escapism after mindless escapism came up on each channel until he chose an old episode of come crime drama he had liked. Nearing the end of the episode Jenna got up. Peter heard her running the shower and her radio blasting from her room, finally she emerged, fresh, clean and morning faced.
"Hi dad" she called on her way to the kitchen.
"Hi sweetie, did you sleep well?"
Jenna entered the living room with her OJ.
"yeah, ok, bit late though"
'worn out too I expect' Peter thought.
Jenna slumped down on the couch next to Peter and swung her legs over his lap to stretch out.
"So what's going on with you today?" she chirped.
Peter laid his hands on her legs and smiled "nothing much" he said "lazy day today"
"mmm" she said, "me too, nothing on, I kinda like that, its been busy lately"
