It was January 2001 and Jason our younger brother had gone with our parents up to our beach house for the weekend. Rebecca, my twin sister and I had decided to spend the Friday night at home and watch a movie on DVD. Bec and I had just turned eighteen and had always been extremely close so spending time together was a regular thing.
Over the past four years Bec had developed into a beautiful young lady and was popular with everyone she met and a target for all the young men in our area. I used to feel quite jealous when she would bring a boyfriend home and I had difficulty understanding this so I put it down to being protective. She had a beautifully proportioned figure with straight long blonde hair and nice size boobs. Bec had a great sense of humour and we used to tease each other all the time about just about everything, including our boyfriends and girlfriends. We really were great mates.
I jumped into my car and went over to Blockbuster and hired American Beauty to watch because neither of us had seen it. We showered, got into our pyjamas and settled in on the lounge to watch the movie.
Just after the opening credits, there's a scene where Kevin Spacey is in the shower with his back to the camera, masturbating. I cringed a bit at the scene hoping it would slip by unnoticed. Just as the shower scene finished Bec turned to me and asked "do all men do that?"
"Do what?" I asked knowing exactly what she meant.
"You know, jerk off?"
"Hey Bec, how would I know what all men do?"
"Do you do it?"
"Look Bec I reckon all men jerk off, it's perfectly normal. Can we watch the movie now?"
After a short pause Bec asked "How often do you do it?"
I was getting a bit annoyed by her questioning so I thought I would shock her to try and shut her up with a bit of humour so I said "Look I do it at least five times a day and if you keep this sort of talk up I'll want to do it right here and now".
There was a short pause before she said "I've never seen a boy do it right to the end".
I stopped the video noticing a mild tingle in my groin at the nature of the conversation "What do you mean to the end?"
"Until they cum."
"Haven't you done that to Andrew your boyfriend?"
"No, not until he came anyway. He always wants me to play with his cock but we stop short of ... you know ... him ejaculating."
"Why are you telling me all this Bec, I mean ..."
"Would you let me watch you?" she said.
I could feel my cock starting to get hard inside my pyjama shorts and I was a bit confused seeing that this was happening with my sister "Are you serious Bec, you want to watch me jerk off?"
She slid across the lounge to be right beside me and said "Yes."
As I sat there looking into her eyes all my rational thought was quickly replaced by my quickly mounting sexual arousal. The thought of masturbating in front of my sister wasn't new to me because I had fantasised about it on a number of occasions.
"You're not winding me up are you, your really would like me to?"
Rebecca answered by sliding her hand over onto my now fully erect penis and squeezed it softly.
"Look, if I'm to do this for you, you have to swear not to tell a soul. I mean, a lot of people would take it the wrong way."
"I swear" she said.
"Here?"
"Why not?" she replied.
"Would you get some tissues?"
Bec nodded and went to the bathroom, returning with a box of tissues.
I lifted myself off the lounge and slid my pyjama shorts off revealing my erect cock standing to attention. Bec couldn't take her eyes from it and began fondling me and slowly stroking it.
"Do you want to do it for me?" I asked.
"No I'll watch what you do" she said.
By this time my arousal had reached fever pitch and pre cum was beginning to bead and run from the eye of my cock. I dipped my finger in and pulled it away watching the viscous clear fluid stretch for about six inches before breaking. I closed my eyes and gently rubbed the rest of my pre cum over the head of my cock in circles. I opened my eyes and looked at Bec who was mesmerised by the show. The thought of Bec watching me was almost too much to bear so I started slowly stroking my cock with my right hand. I really wanted to cum and let her watch me ejaculate.
"Talk me through it Tony" she said.
"OK" I said "I'm pretty excited so it probably won't take too long."
"What do you feel?" she asked.
"It just feels great, I'm so horny and need to cum so badly."
I kept stroking by moving the loose skin on my shaft up and down with a steady rhythm. My cock was hard and tight with blue veins standing out and winding their way around my shaft like a cylindrical roadmap. Soon a very pleasant sensation spread into my pelvic region and I felt my seminal fluid flow into my urethral bulb; it only lasts a fleeting second but the sensation is quite distinctive and is the first sign of my impending orgasm.
"I'm getting closer" I said.
I stopped stroking for a second or two and cupped my balls with my left hand. The feeling was sensational and I wiped a huge bead of pre cum from the eye of my penis and slipped it into my mouth.
"I adore mild saltiness of my pre-cum." I mumbled.
I released my balls and returned to stroking. The sexual tension within my body was palpable, and the build up towards my orgasm intensified. I moved my hand up the shaft so that my thumb was over the corona where the swollen head of my cock stands proud from my shaft. Momentarily I returned to tickling my frenulum with a single finger using my pre-cum as lubricant. Then, with two fingers on the underside and thumb on top I increase the pressure on my cock and started stroking at a faster pace.
"Oh Bec, I'm getting really close now, would you hold my balls as I cum?"
Bec immediately cupped my balls with her hand and as the feeling of impending orgasm spread throughout my groin I began slowly thrusting in time with my stroking.
My hand slid up and down the shaft now; easily and smoothly just like it's done it so many times before. Pre-cum was flowing out of my slit and dribbling down over my bulging cock head. I start to feel the tension of my built up sperm travelling from my prostate up the shaft of my cock seeking release.
"Nearly there Bec. Oh yes...." Then with a rush I'm there, the world stops, time stops and all sensation is centred on my cock head.
"Oh God Bec I'm cumming. Oh yes. Mmmmmh. Oh yes. I'm cumming, I'M CUMMING, I'M CUMMING......."
My breathing stops momentarily as my body tenses. My cock has become the centre of the universe and sensation is magnified to extreme proportions. I exhale and indescribable pleasure overcomes me as I ejaculate a huge rope of cum that disappeared over my shoulder in Rebecca's direction. I kept stroking and a with a second contraction another load of cum shoots onto my upper chest leaving a thin trail all the way down to my cock. I raise my hips to aid the next release and watch my cock exploding and releasing its creamy white lava onto my stomach.
"Oh fuck" I hear Rebecca remark.
Contraction after contraction expels more and more semen from my cock. Bec is still holding my balls as my orgasm and ejaculation subsides. My chest is covered in cum and a pool has formed at the base of my cock. I'm lying there recovering my senses as my breathing slowly returns to normal.
"Wow" Rebecca says "That was amazing."
"Look at this" she said pointing to the right hand shoulder of her pyjama top.
