All week I'd found it difficult to focus on anything. I messed up my politics essay, flunked my history exam and was subbed for the first time in my fledgling football career. Luckily the team won despite my abject display. I simply couldn't concentrate, all I could think about was my sister, Alice, playing with her pussy while she watched me stroke my cock. I'd been afflicted with an almost permanent erection and had to resort to various tricks to disguise the persistent bulge in my pants. I masturbated as often as I could, to relieve this debilitating condition, but the subsequent respite was always short-lived.
Saturday morning, I woke up, as usual, with a tent pole between my legs.
The question was, should I grab a handful of tissues and go for a quick wank, as I had every morning since last Saturday, or hang on and hope for 'something more'. There was always a chance, however slim I'd be alone with Alice again.
I allowed my erection to subside and went downstairs for some breakfast.
Mum and Geoff (my stepfather) were tucking into scrambled eggs.
My older brother, Tom, slurped down his coffee and shoved his empty mug into the sink.
"Sorry haven't got time to wash it up, I'm late for training." He called back, as he scuttled down the hallway and out of the front door. One down!
My youngest sister, Becky, was playing with her cereal, swirling the coco-pops around in the milk creating a brown mush. Alice was sitting at the far end of the kitchen table, drinking tea and nibbling on a slice of toast. She was wearing her skimpy night-shirt, which left very little to the imagination. In fact, illuminated by the bright morning light, it was virtually see-through. She really did have amazing tits! I sat down quickly, to hide the renewed swelling in my shorts.
"Can, someone pass the cornflakes?" I requested. My impromptu erection safely concealed under the table.
My mum obliged. I shook some into my bowl, poured on some milk and began to munch away. I glanced up as often as I could manage without being too obvious, to enjoy the view of Alice's pert mounds. I noticed I wasn't the only one taking in the view, Geoff, the dirty old sod, was also having a good old stare. I wondered if he also had a stiffy. I felt a sharp pang of jealously. I hated the idea any other male, especially Geoff, taking pleasure in the sight of my sister's hot, young body.
"Geoff and I are going shopping, who fancies coming with us?" Mum asked.
"I want to stay at home and watch TV!" Becky whined.
"No, you're coming with us, you need new shoes for school." Mum insisted. Becky started whinging about never being allowed to do what she wanted, but luckily her protests fell on stony ground
"Alice, how about you? There might be some clothes in the sale." Mum suggested.
Damn! The offer of new clothes.That was sure to tempt her out of the house. It looked like I'd be on my own after all, which before last week I'd have considered cause for celebration. All alone, to play with myself, with no danger of being caught in the act...now of course, being caught in the act was exactly what I wanted.
"I really ought to stay and do some revision we've got a biology test on Monday." She replied, to everyone's astonishment.
"Geoff, did I hear that right? Mum asked.
"My daughter is choosing homework over shopping for new clothes?"
"Yep, you heard right!" I do believe our Alice is growing up. He stood up, squeezed her shoulder affectionately and smiled down at her.
"Filthy, pervert!" I seethed inwardly. In hindsight it was no doubt a genuinely innocent show of affection, but I wasn't, in that moment, capable of rational thought.
From what I'd witnessed last Saturday, Alice was undoubtedly growing up and my darker feelings told me that's exactly the kind of 'growing up' Geoff was thinking about!
"It'll be good to get on without being interrupted." She explained.
"You hear that, Adam? No distractions and that means no loud music." Geoff semi-frowned at me.
"Yeah, yeah...OK!" I snorted.
"Fuck off Geoff and stop ogling my sister's tits!" I thought.
"Alice...If you need a hand revising." I offered.
"Ok, thanks, I might take you up on that." She smiled. I detected a naughty glint in her eye, at least I thought I did.
"Is there enough hot water for a bath?" I asked. "I'm feeling a bit stiff." I glanced at Alice.
A wicked smirk danced, briefly across her face.
"Football was, really tough, last night." I explained, just in case I was being a bit too obvious.
There's probably enough for one bath, Mum replied.
"You had a bath last week." Alice declared."Remember?" She added, an unmistakably naughty glint in her eye.
"But I am really feeling very stiff this morning...I really could use a hot bath." I protested.
"Well, I did quite fancy one myself." She responded. "It'd be good to relax before I get down to revising...you don't mind, do you?"
"Well, I suppose that's only fair." I conceded. "I guess I'll just have to find another way to relieve the stiffness."
"My teenage son and daughter being civil to each other, will wonders never cease?" Mum sighed happily, clearly oblivious to the carnal undercurrents.
"Well, we'd better be off, before the carpark fills up!" Geoff announced.
"Yep, come on Becky, let's go!" Agreed mum clapping her hands, ushering my pouting baby sister out of the door.
When they'd gone, Alice leant back in the chair and stretched her arms upwards.
"I must admit, I'm feeling a bit stiff myself". She moaned, arching her back and pushing her firm round breasts forward shamelessly, her erect nipples pressing invitingly against her night-shirt. The bright sun highlighted her perfect contours. My own stiffness was becoming decidedly more acute.
"I think I'll run that bath."
