Sibling Lovers

My older sister (60) and I have been in a secret romantic and sexual relationship for the past 2 years. we were always close in a conventional way, each got married and started very conventional families. however a few years ago, we both lost our spouses at around the same time. my wife died of cancer, her husband died in a car accident. we became much closer during this time, supported each other, even going back and forth between staying at my place and hers. months went by and we became much more comfortable with each other, to the point that we would watch movies together and fall asleep embracing. it was around this time that one night over some wine and reminiscing our youth, she brought up something i thought she didn't even remember to begin with, something that happened during my 20th birthday. we both went out for drinks with our mutual friends, had a good time. but she had gotten extremely drunk so we decided she'd crash at my place. my roommates were not home. as i left her in the couch, she blabbered something about helping me with my confidence. I was insecure and a little wimpy back then, and she was the confident, sexy type that has a world of men wrapped around her finger (she still is at her age. she really takes care of herself and looks 20 years younger). she had me sit by her side, told me to trust her, and jumped on me to kiss me. i tried to stop her in shock but she told me it was ok, that we wouldn't really have sex. she kept on kissing me and jerked me off until i finished, then licked her hand and my dick clean and told me to go to bed. I was very awkward with hr the next morning, but apparently she didn't remember anything. she just asked me if she had slept with anyone, said i couldn't possibly know. and we didn't bring it up in all these years, though i thought about it a lot. i do confess that, even though i loved my wife very much, sometimes i fantasized with my sister while making love to her.

So my sister brought it up all those years later and confessed that she did remember, just pretended not to because of the taboo around it. but being as liberal and open minded as she is, she confessed that she was attracted to me and always felt curiosity about crossing that barrier. I confessed i did too. we agreed to keep it a secret, and keep it casual, and made love right there.

But casual, it has not been. we really connected. and gotta say, sex in a relationship of such nature is very different, more intense. we both had great sex with our spouses most of our lives, but this... is something else. but more than that, we fell in love. we even think of each others as our new spouses. no one knows about us, it's a complete secret, we only act as a couple behind close doors or on our weekend getaways, which we try to do as often and as far of home as possible (it's very exciting to act as a couple out in the open). we don't have much family and our children live abroad, so we don't have to worry much about them, only about acting as run of the mill aunt and uncle when they're around. other than that, it's the dirty, sexy secret we're willing to keep for the rest of our lives.
