I was desperate for a girlfriend. 18 years old and I'd never even got to first base. I was always a bit awkward in the presence of females and having been to an all-boys school, had very little contact with members of the opposite sex. Consequently I spent a lot of time jerking off. First thing in the morning when I woke up with the inevitable tent pole, or before I went to sleep, fantasising about Emma, the girl (well, 25 year old woman) next door.
Practically speaking, having three siblings (an older brother and two sisters) a mother and a step-father lurking around the house, masturbation was mostly a functional affair and to be fair, ejaculation was quickly and easily achieved.
On the rare occasion the house was empty, I would take the opportunity to indulge in that most enjoyable of pastimes, a long, slow wank. Sometimes lying naked on my bed, staring at women with natural breasts and hair between their legs, in a dog-eared porno mag. (This was long before the days of internet porn and shaved pussies).
But my favourite way to masturbate was in a hot bath. This of course depended on there being enough hot water in the tank.
This particular day I was in luck, everyone had gone out after a quick wash, or in my slob of a brother's case, not bothering to wash at all. I turned on the taps, my cock already stiff in anticipation. Not having a girlfriend this was, sadly, as exciting as it got. I lowered myself into the steaming, hot bath. I'd learnt to make it as hot as I could bear, otherwise I'd end up in lukewarm water, which wasn't the best environment for an orgasm. The hot water also helped my cock and balls swell to their maximum size and naturally the more engorged I was, the better it felt.
I slid my soapy hands slowly up and down the shaft of my erect penis, creating a lather, peeling back my foreskin and caressing the rim of my helmet. Expertly, and I had certainly achieved expert status, I varied the speed and pressure, squeezing my shaft and gently caressing my shiny tip. I could have cum in a matter of seconds had I wanted, but I'd learnt the art of stopping myself just before ejaculating. I reckon on a good day I could edge for about half an hour.
I'd probably been edging for about 10 minutes, when I heard the front door being opened.
"Anyone home?" A voice called out. It was my sister.
Alice was just over a year older than me, and dare I say it, she was hot.
My friends all wanted to get inside her knickers.
I confess, I'd had more than the occasional inappropriate thought myself, especially when she was wearing her tight pyjamas or skimpy nighty. It was impossible not to stare at her firm round buttocks and curvy young breasts, which were, as my friends often remarked, "Fucking great tits!"
I'm sure she'd caught me stealing a look on numerous occasions, but to be fair she'd never objected. In fact, sometimes I was sure she was deliberately leaning across me, or bending down, so it was difficult not to take in the view.
"Hello! Anybody there?" She called out, as she started up the stairs.
I didn't answer. Should I say anything?
The bathroom door was unlocked.
What if she came in and caught me? The idea made my head swim.
Would she be shocked, disgusted, amused...aroused?
I decided to keep quiet. My heart pounded with excitement as my hand slid up and down the shaft of my cock. The possibility of my sister catching me masturbating in the bath was exhilarating.
The floorboards creaked as she approached the door. I held my breath.
I stopped stroking in case she heard the water splashing. I lay there, the palm of my hand wrapped around my pulsating pole, still allowing my thumb to slide gently over my swollen tip.
I was desperate for her to come in and catch me.
My pulse raced as the sound of her footsteps grew louder, then stopped. I held my breath, there was a click and the door handle turned. My heart skipped a beat.
Alice appeared in the doorway. Initially she didn't notice me, waving her hand in front of face, no doubt surprised by the steamy atmosphere. I just lay there, motionless, hand on cock, waiting for her to see me.
She turned her head and shrieked, taking a step backwards.
"Jesus, Adam, you scared the shit out of me! I thought everyone was out. You could have given me a heart atta..."
She paused and her eyes widened. "Oh my God!" She gawped. "Are you playing with yourself?"
I blushed, violently.
"Ha! you're lucky it wasn't Mum!" She laughed.
It wasn't quite the erotic moment I'd imagined, I was just embarrassed.
