I opened the shower door and my 8 inches became hard against the cold air, at 16 my cock was still jumping up at the slightest touch, the slightest thoughts or even when I was just slightly bored. I sat down at my desk chair in my towel and checked my email.

A knock on the door and my 18 year old sister Jess entered the room. She was wearing a tight boob tube and hot pants, her D boobs were perky and her nipples pushed through the material. She was my sister but her blond hair and blue eyes and most definitely her attire made my penis begin to rise. Jess noticed and gave a giggle as my towel made a tent. Embarrassed i asked what she wanted.

She replied, “Can I borrow £10? I’ll pay you back,”

She was always asking for money and she never payed me back so I knew straight away that I was going to say no. When I told her this she rolled her eyes and stormed out the room. When the door shut I took off my towel and reached for my boxers. During the half second I was naked Jess opened the door, most likely to ask again or more likely to try and grab it off me. She saw me naked and stopped. The door closed and for the longest five seconds she looked me up and down. I was frozen; I didn’t know what to do.
The silence broke and Jess said, “I have an idea. Why don’t I make this interesting? If you lend me some money I’ll let you touch my boobs for a whole minute, do whatever you want. And I’ll pay you back all the money I owe you! Sounds like a deal?”

I didn’t expect her to say anything like that but my innate human nature forced me to agree. I opened my wallet and gave her the £10 note. I stepped forward and she sat on my bed. She took off her boob tube and there she stood her magnificent breasts like bountiful grapefruit. I stared but quickly realised that my sister was already counting down. I took my right hand and placed it on her right breast and her nipples became as erect as my member. I started to feel and squeeze. She felt amazing and I took my left hand and did the same with her other boob. Squeezing both I lowered my face and pushed them into her cleavage. I smelled her and it was wonderful. It was then that I realised that Jess had stopped counting and was smiling. She laughed, got dressed and left.

That evening I had the best wank off my life and shot several ribbons of cum across the room, the farthest and most I had ever done. At around 1am I went to bed and fell asleep. I awoke later to the sound of loud footsteps and noisy talking. It was Jess and she was drunk. I heard her stumble upstairs and then a strong crash and she fell into my room. I got out of bed and helped her up. She smiled at me and the smell of vodka and other drinks was repugnant on her breath. Then to my surprise she pushed me onto the bed and kissed me. Her tongue pushed her way into my mouth and began feeling the back of my throat. Not knowing what to do I let her lead and she broke the kiss breathing deeply and rolling onto the other side of the bed.
We both lay there until she said, “Are you still a virgin?” I meekly replied yes and she gave a high pitched snigger and asked, “Would you like to change that… Right now?”

Shocked and stunned I thought about it. I had never thought about sleeping with my own sister. Sure she was hot and sure she dressed like a $20 prostitute but she was still my flesh and blood. I thought about the fact that she was drunk and probably wouldn’t remember and that my geeky persona would probably mean I wouldn’t get laid for a long time anyway. I turned to her and nodded.

Jess got out of the bed, stood up and then began to strip, drunkenly singing she first took off her shoes and as she bent down took off her pants. She stood up and saw this gorgeous blond big chested girl wearing only a bra and a thong. I became hard and she made me stand and told me to get naked. I took off my clothes and threw them into a pile and touched her breasts again. They were warm and soft. I undid her bra and let her D-cups hang. I took a step back and stared. They were even better than previously especially out of the bra. She kissed me and once again her tongue entered her mouth. We kissed passionately and her hand stroked my chest and rested upon my throbbing cock. Standing hard and at its fullest height she spat into her hand and began to rub it up and down. It felt fantastic and I instantly came. Embarrassed I stopped kissing her and turned away. I sat down on the bed ashamed. She told me she didn’t care. To my surprise she got on her knees in front of me and started to lick the cum dribbling from my cock. I became more confident and suggestively started to guide her mouth to the head. Sensing my needs she began to suck tickling the head with her tongue. She took a deep breath and forced my 8 inches down her throat. She gagged and gasped but after a momentary breath tried again. Inch by inch she swallowed my cock. It was the greatest feeling.

Whilst I was mesmerised by tonight’s events she lay me down on the bed and sat on my chest. She looked me in the eye and winked. Crouching over my cock she held it in her hand. With her other hand she took my palm and placed it on her pussy. She showed me where to rub and as I did so she moaned in pleasure. Then before I knew it she had placed her cock in between the folds of her pussy and I had penetrated her. That moment of rubbing her and my cock being inside made me felt closer to her than I had ever felt before. We were physically joined like a single person. Crouching over me with her vagina filled with my cock she began to move up and down. With each pass a wave of pleasure swept over me and I realised I was about to cum once more. She saw the fear in my face and bent down to whisper to me that she was on the pill. I relaxed and allowed her to continue moving up and down upon my sword.

Sensing when I was about to come she got up and lay on top of me with her head on my cock and her pussy in my face. She started to suck again and I realised she wanted me to do the same to her. I nervously opened my mouth and thrust my tongue into the depths of her womanhood. I held her enormous tits and enjoyed the frenzy of physicality. The moment became pure when I came. She got up and we kissed. The taste of my cum in her mouth was salty and strange but it was passionate nonetheless. Our bodies moved together and her face was sticky with my sperm. She swallowed the last of the cum and gave me a parting kiss. She touched my cock and with a finger put the last of my semen in her mouth. She licked it with immense pleasure, gave me a final wink and left my room, naked.
