A long time ago when I was sixteen, my sister who is very close approached me and explained she had a date with a divorcee. She had given him the impression that she was sexually experienced, but she wasn't. She asked me if I would show her what to do with his cock. I said ok but fairs fair, you've got to show me too. She was expecting this because she took off her dressing gown and was nude underneath. She wanted to know how to wank him, etc. I showed her and she introduced me to her clit, something I didn't even know existed at the time. SHe saw the man but they didn't get on.
Some time later she asked me if I would go to her friend Pat's and show her the same. When we got there Pat who was a bit overweight but not bad looking couldn't wait to get us in her bedroom and naked. She said she had read a lot but never touched a penis before. I lay on her bed with the girls either side of me. Sis showed her what to do, she was so eager I had to tell her to stop or I would come too soon. She said I've got to come. she started masturbating right in front of me. Sis joined in, fingering her while she rubbed her clit. After she came she was still very keen, she started wanking me and it was too much I shot all over my chest. Sis fetched some tissue. Pat said let me look at it first, I've never seen come before. She put her fingers in it, sniffed it and played with it, then she tasted it from her finger. Sis wiped the rest away, and Pat tried to wank me again. I said it's too soon. Sis said we'll have to get him hard again. Let's give him a show. I got off the bed and they started fingering and then licking each other, they'd obviously done it before. I was hard again in no time. Pat noticed and said please fuck me. I said not without a condom. Pat said no problem and had one ready by the bed. She put it on for me which got me close again. After my first fuck which lasted all of two minutes, Pat wanted to remove the condom. She was really excited and wanted to see everything. They managed to get me hard again after a rest and I fucked her again.
The next morning my sister had gone out and Pat phoned. She asked me to come round again and promised anything I wanted. I went. Without sis there she was even more excited. She said I'll do whatever you want but please come in my mouth. We had a great time.
We've had a sex, not love relationship for over 20 years now. We've both been married and divorced. I've seen her masturbate with all sorts of dildos and a fucking machine. She loves come and has taught herself deep throat. She's been wild for ever and just loves sex. She's asked me to move in, but I think that might spoil it. She still sees my sister and although they won't sex I think they still have sex too. She's always asked me to get more men but I'm too selfish for that.
