My younger sister moved abroad as soon as she left uni, marrying her Italian boyfriend. As a result we've only met up every couple of years or so. I'm 50 now, and she is 47.

A couple of weeks ago,mshe called to say she was coming here to sort out a legal issue. Could she stay overnight with me to save hotel costs?? Of course, I said without thinking.. I live in a one-bedroom apartment.

Anyway, I met her at the airport and took her to the attorney's office she needed to visit and then, her business done, we headed back to mine, and I cooked her dinner.

Then it came to bedtime.

We had only slept in the same bed together once, when our ages were still in single figures, and Mum hand put a bolster pillow down the middle of the bed to stop us fighting!

Now I asked her if she wanted to sleep on the sofa, or if she would prefer if I did. She seemed happy we should share my bed, though there was no sexual inclination on either side.

I got into bed while she went to the bathroom. She came back wearing just her panties and a skimpy t-shirt. I thought to myself how she still looked like a student, even though she was now 47. She climbed in beside me, and laid down. It was obvious neither of us was actually ready to sleep.

I said that I usually put a porn movie on to send me to sleep. She laughed, and said 'cool', so I clicked on my favourite on my iPad... pornhub/view_video.php??viewkey==650246653 .... It's a compilation of guys cumming on girls....

The iPad was pointing straight at me, but she moved it so she could see better... That said something to me, and I immediately felt even more aroused....

So now we were both watching these handsome penises spurting cum all over pretty girls...

Next thing I knew, I felt a hand touch my cock...

She took me in hand and started to wank me...

That felt so good! I felt I should say something, but I didn't know what to say...

I reached across and found her panties.. Pulled them aside and found her pussy... Mmmmmm!

I thought, we shouldn't be doing this, but we were both adopted, so not blood brother and sister. I slipped my finger into her vsgina, and it was delightfully tight...

Now she pulled my hand away, but moved astride me, rubbing my cock against her clit before guiding it into her... She sat down right on top of me, so my cock was as far as it could go into her, then gently rode me as she watched the spurting penises on the video...

Just looking at my cock in her pussy made me even more horny... I rolled her onto her back, and drew her legs up behind me... Now I could see my cock sliding in between her pussy lips... Her hand came down and started to masturbate her clit.... Lovely to watch!

I thrust steadily into her as she wanked... Mmmmm... I wanted to time it so she came first.... It was close! I felt her wanking even harder, breathing faster, then her pussy suddenly flooded as she came noisily... I knew I couldn't hold on any longer... I pulled out and sprayed my sperm all over her!

The next morning was calmer ... I woke with a hard on, finding her sleeping with her back to me ... I slipped into her from behind with ease, and we just made love gently for an hour at least....

I'm looking forward to the next time she comes here..,
