Colin woke it with a stiff cock and a pain in his stomach, he needed a pee, he struggled upright and switched his bedside light on: six o'clock. It was Saturday and he didn't need to get up this early. However his full bladder had decided otherwise. He got up and walked out the door naked, no one would be awake at this time. He walked into the bathroom, not understanding why the light was on. It had been years since the bathroom light had been left on overnight. He moved to the toilet, still half asleep.
"Whoa sexy don't start yet, I'm still going."
Looking startled he saw his sister Sue sitting on the toilet, her nightie hitched up to her waist.
"Ohh sorry Sue, not awake, need to pee," he half said, half mumbled. He sat on a towel on the edge of the bath, staring at Sue.
Sue finished and wiped, dropped the paper into the bowl, stood and flushed. Colin ambled over and as he went to hold his dick, Sue beat him to it.
They shuffled in front of the toilet and Sue lifted the seat. She pointed his prick down towards the bowl. Colin relaxed and his pee came out, partly in a thin spray and partly a dribbling dripping stream.
"What's happened?" said Sue giggling at the mess that was going everywhere," most of it's dripping on my hand."
"Ohh no, because I needed to pee my body gives me a hard on until I woke up, but 'cos it's been hard the pee's all mixed up, due to the tube it's coming down being restricted as my body thinks I'm going to cum."
As he said this the two streams can together in full flow. Sue squeezed his dick until the flow stopped, then let go, then squeezed, smiling as the little javelins of piss hit the water and broke up. She moved her hand in an arc creating a swirling ring of piss, then up and down trying to make shapes in the air above the toilet. Slowly the jet of piss slowed. It finished with a trickle and dribbled over Sues fingers on the underside below the head. Sue sighed and reluctantly let go of his prick. His cock hung down and slowly contracted in the night air. All that she could see was the head peeking out of the thick hair around it.
Sue kissed Colin on the lips and ran her hand over his arse. Colin placed a hand over his sisters tiny tit, gently massaging the nipple with his palm. She broke the kiss and walked away out of the bathroom, leaving Colin standing, naked and with a rock hard cock. He shrugged and walked back to bed. Closing the door he was surprised it was dark in the room. He thought he'd put on the bedside lamp. Dreaming again he thought, pulling back the duvet and climbing in. His leg touched something soft and warm, another leg. So Sue had come into his bed, He pulled the duvet over him and snugged up to his sister, She smiled in the dark and brought her arm around and pulled him close, he kissed her nose then nuzzled it. Their lips met, briefly, then they dropped off to sleep.
As the sun rose, neither heard his door open, or see their mother peek in and astonished see them in bed together. Concerned she walked to the bed and sat on it. Colin registered the change and slowly surfaced from his sleep. He realised Sue was with him as they were spooning and her arm was wrapped round his waist. Sue was unaware of the situation and continued to dream happily.
"Oh! hi Mum, err, Sue had.. a nightmare and came to me to ... you don't believe a word of this do you?" he mumbled.
His mother shook her head and put a finger to her lips. Standing she quietly left the room closing the door.
"Fuck!" murmured Colin and pulled the duvet up to his ears again.
A while later Colin felt Sue's hand begin to circle round his stomach and her body pressed into his.
"Hi baby, sleep well?" she murmured , moving her head to gently kiss his ear.
"Too well Sis, Mum found us, she was here earlier, guess we're well and truly screwed." he said, taking her hand in his.
"Oh no! I'm sorry Col, I really am, it's my fault, I shouldn't have sneaked in here, but I wanted to be near you so much." she squeezed her fingers in his hand.
"Well whatever else, it's in the open now, look I have to pee, think I'd better go on my own this time," he threw back the duvet and flipped it back after he stood. Padding out to the toilet he did what he had to and turned to go back to his bedroom. As he came back their mother followed him in to the bedroom, smacking his bottom as he reached the bed.
"Good morning boys and girls, does someone want to tell Momma the story. You know boy meets girl, they fall in love and sleep together, except they're brother and sister and it's illegal and wrong." She smiled without mirth and her face set in a determined manner.
"Mum, it's my fault.." began Sue
"It isn't Sue, we're both responsible for what's happening. You didn't force me, I was a more than willing victim." finished Colin.
"I'm the oldest and I should have been more responsible" Sue jabbed him in the chest with her finger. Sitting up she had forgotten that she had taken her nightdress off, her bare breasts bobbling slightly as she poked him. Her mother raised an eyebrow and stared at her breasts.
"Ohh!" Sue said and defiantly placed her hands on her hips, pushing her tiny breasts up and out towards their mother. "There's nothing to see, I know they're small, don't stare!"
"Sue, that's very rude, I'm not judging the size of your breasts, I'm merely concerned that you are exposing them to the world, it is most unladylike."
"Mum, she is a lady, and this is my bedroom, which is a private place. Personally I think they're perfect, they fit her body exactly and I hope to see Sue like that for many years to come."
"Thanks bro."
"Welcome." They high fived
"Right, fun's over, better tell me what's happened, and why you two are cozying up together and naked too.
"Mum, for some unknown unfathomable stupid, idiotic reason, I have fallen head over heels in love with your youngest son. I don't know how or why, I can also sayI can't tell you when, I'm so confused about this, but, I love him to bits."
