At the time of this account my sister, Irene, and I were in our forties. She is a year younger than me. She had divorced her husband when he had gone off with another woman. A month or so after that my wife was killed in a car accident. So Irene and I now had no spouses.

She bought a house in the village where I live and we often visited each other in the evening when we not at work. I wasn`t expecting her that fateful evenig and was watching a sex video on my computer and was stroking my cock, intendig to masturbate on to a newspaper I had put on the floor and had a full erection when the doorbell rang. Putting on a dressing gown I went to the door and my sister was standing there. I invited her in and we sat in my lounge, chatting and drinking wine.

"Why on earth are you wearing your dressing gown? It`s a bit early for going to bed" she said.

"I was watching a blue video on my computer and was naked when you rang my doorbell so I put it on to open the door".

"Blue video?" she asked. "I`ve never seen one. I don`t have a computer. Will you let me see the one you were watching?"

"If you like. I`ll replay it".
 
When the video was running for a little while Irene said "My word. That`s naughty. It looks like a naked man is having sex with a naked girl. He`s lucky, isn`t he? Now he`s pulled out and is cumming on her chest. I`ve never seen a man and woman doing that. It makes me feel a bit horny".

"Me too. I`m getting an erection".

"Let me see your erection, Peter".

"All right. I`ll open hy dressing gown and you`ll see it".

"No . Take it rght off. You said you were naked watching the video. I want to see you like that".

I took it off and she said "My goodness. It`s very big and fairly hard. Can I touch it".

"Please do and hold it it you wish".

When she held it she stroked it. She was masturbating me. I loved it.

"Keep doing that and I`ll cum".

"No I won`t take it that far but I`m even more horny seeing you naked. I`d like to undress and be as naked as you".

"Go ahead and do it" I said.

She went into the lounge and returned quite naked.

It was the first time I`d seen her like that since we were young children and that didn`t mean a thing in those days. What a difference!. She had a wonderful figure. Pert breasts, hard nipples, flat stomach, long legs and shaven pussy. She took my cock again in one hand and I slipped some fingers into her cunt.

"Now we can masturbate each other" Irene said.

We did. She held my eraction firmly. She stroked me and I teased her clit. My cum shoy out on to the newspapers on the floor and I made her cum three or four times then we returned to the lounge.

"That was a lovely jerking off you gave me, Irene".

"So was the masturbation you gave me. I haven`t cum like that for a long time. It wasd a loty better than when I do it to myself. Some time ago we told each other that we masturbate because we miss the sex we used to have. So why don`t we have sex tomorrow insted of masturbating?"

"If I fuck you it would be incest2.

"Of course it would but neither of us have had sex for a long time. We haven`t got anyone to do it with so why don`t we go ahead and do it? We won`t tell anyone, of course".

"Yes. Let`s do it. When you come here tomorrow I`ll fuck you".

Naked, in my lounge, we masturbated to get ready to fuck. Irene told me that on her way to work that morning she bought some condoms for me. We could fuck safely as often as we liked.

She lay on the floor and opened her legs for me. What a wonderful sight. Her naked body and open cunt inviting me in. I put on a condom and lay on top of her. Gently, put the tip of my erection into the entrance to her vagina.

"Now go right in, Peter. Fuck me. Fuck me. Oh! That`s lovely. I`m cumming".

"So am I" I gasped as I shot my cum into the condom.

I fucked my sister until she was satisfied. It wasn`t the only time we fucked. We did it almost daily, first using condoms then she she bought some pills and we could do it flesh to flesh.
