I stumbled home at about 3:30am, struggled to get my key in the door, eventually gained entry to the house, and staggered up the stairs to my bedroom. Bouncing off both sides of the doorway, I almost fell into the bedroom and collapsed on my bed. I was so drunk, I forgot to close the door.
I lay there for a few minutes trying to steady my reeling brain. It had been a great night out with the lads, starting in the bar and moving on to the nightclub. We had all got really drunk, been quite boisterous, and had a tremendous laugh.
In the nightclub we had bumped into a group of girls who we had proceeded to chat up and buy drinks for all night. There was one of them in particular I had been flirting with, a tall blond with huge tits. Her and I had met in the corridor outside the toilets and had a passionate kissing session, during which both of our hands had wandered all over the others’ body. The girl had me so turned on and gagging for sex that I asked her if she wanted to leave with me early. She had refused, saying that she wouldn’t go away without her friends.
At some point in the night, the girls disappeared, and we all had to go home without getting anything more than some kissing and feeling up with them. Who knows why they abandoned us? All I knew was that I was home, completely drunk, and horny as hell. I try to never go to sleep loaded with this much of an unreleased sexual urge; I had to free some of it or I wouldn’t get a good sleep.
I slowly and clumsily got undressed, and lay back on my bed to masturbate away the tension in my balls. Taking my dick in my hand I started to massage it hard, imagining the big breasted girl who had abandoned me in the club after getting me so worked up.
I lay there for a while, stroking away at my cock, taking my time and enjoying the release of the pent up pressure.
Suddenly I became aware of something. I opened my eyes slightly, and, in the corner of my vision, finally noticed that I had left the door open. But the frightening thing was that there was someone in the doorway, standing watching me.
Had I been more sober I would have jumped with fright and cowered under the covers, but I was so drunk that I just looked stupidly over to the doorway with my eyes widening in shock. My hand had stopped moving, but still held onto my slightly softening dick.
Samantha, my 18 year old sister stood in the doorway. Sweet young innocent Samantha, dressed in a knee length night shirt, her shoulder length red hair tousled and messy, her green eyes wide and staring, stood there watching me masturbate. How long she had been there I could only imagine.
In my hand, my cock twitched and stiffened. Behind the drunken haze where my brain lay, I wanted to be horrified and shocked, but I was actually really turned on by the fact that my sister was watching me. My hand started to stroke up and down my shaft again as I lay there and looked over at Samantha.
Her eyes never left my hand and dick. She stepped forward into the room, slowly, nervously. She closed the door behind her, her eyes following the movement of my hand the whole time.
She slowly walked across the room to stand before my bed, looking down at my cock being manipulated by my hand. My head was whirling; I should be jumping up, forcing Samantha from the room, hiding my erect manhood from her, and certainly not continuing to stroke myself as she stood there watching. But there was something incredibly exciting about the fact that my innocent little sister was standing there mesmerised by my masturbation.
Samantha’s eyes came away from my dick for the first time, her face raised to look at mine, and in her young green eyes I saw curiosity and amazement. As I lay there looking up at her, continuing my administrations to my cock, my head filled with visions of what her young body was like under that nightshirt. For the first time in my life, I had a sexual fantasy about one of my sisters.
Samantha lowered herself, sat on the edge of the bed, and turned her eyes back to my stroking hand. She reached out tentatively, placed her hand on my wrist, and pulled my hand off of my cock. She hesitated for a couple of seconds, my dick throbbed and bulged, then she reached out and wrapped her small slender fingers around my shaft. Her touch sent an electrifying chill through my whole body.
Slowly, carefully, but with measured deliberateness, Samantha began to stroke her hand up and down my rock hard and pulsating dick. I gripped a handful of cover in each hand, my back arched in muscle wrenching pleasure, and every sinew of my body tightened. Had I still been in control, my hand would have been moving as fast as possible for these final few moments, but Samantha continued her slow controlled action, dragging the end out and torturing me with pleasure.
I could see that she was getting tired, that her arm was getting weak and slower, her grip less firm.
“I’m going to come soon, baby,” I whispered, encouraging her that the end was near.
Samantha took in a deep breath, held onto it, and pumped her hand with renewed strength.
When I came, I did so with a force and volume I had never managed to muster before. The first wave of cum erupted from the head of my cock, washing over Samantha’s hand and wrist, running around her slender lower arm and dripping on my thigh. As Samantha continued to pump my shaft, tightening her grip to force every drip of fluid from me, every muscle in my loins tightened and forced all traces of cum from me. It just kept pumping out for longer than I ever remember experiencing, and it felt better than any ejaculation I had known before; the fact that it was my sister who was administering the treatment took the feeling beyond the physical pleasure it is normally constrained to.
Samantha sighed with a happy whimper as she released the breath that she had been holding.
When Samantha’s hand finally stopped moving, and released me, I felt physically exhausted. She had not only drained my balls dry, she had sucked all of the energy and strength from my body. I lay there a physical wreck incapable of moving.
Samantha looked up at my face again. Our eyes locked and she smiled. She slowly rose to her feet, turned and walked away. As she opened the door, she looked back at me, still smiling. The door closed and Samantha disappeared.
