As a teenager myself and my older sister both learned we could put our legs out and behind our shoulders, bringing our pussies very close to our faces. At first it was just fun, then one afternoon I caught her in the position totally naked. And she was licking her pussy to orgasm.
I'd already masturbated to orgasm myself by then, but hadn't even imagined myself tonguing my own pussy. But watching her climax so hard that way, I tried it on my own two days later, without letting her know I'd watched her.
It was utterly amazing and found I loved the taste of my own pussy. That was it for me I was hooked. And for the next few months every chance I got, I was licking and finger fucking myself to awesome climaxes.
Hitting sixteen soon after, I finally admitted to my sister I'd seen her doing what by then I was hooked on. Her response was "So, I've seen you more than once".
I couldn't believe it, she'd seen me masturbating just like she did and hadn't said anything. However a couple of days later she entered my room and asked me if I wanted to get off with her doing the same thing. Our parents were going out, so I said I'd try it.
For the next few years we didn't look back sexually. That night was THE night I realized just how much I loved pussy. Not only did we get naked and begin to lick, tongue and finger our own pussies in our favorite position. But in a first for me, I helped out my sister to reach orgasm by tonguing her pussy too. She'd watched me climax and asked me to gently finger her as she licked her clit. Instead I lowered my head and did what I knew she wanted all along. I slid my tongue right along her pussy slit, and on up to her engorged clit. Licking it st first I heard her moan loudly. So being so close to her face, I leant forward and we kissed sexually for the first time. It was a little surreal kissing her mouth right above her pussy, but to me it added the final element to our sisterhood.
Ending the kiss, I dipped my head and sucked in her clitoris hard, forcing her to cry out with lust. And I continued to suck and slurp away on her gorgeous tasting clit until she came, smothering my face with her love juices.
She unfurled herself so we could lay together. Then we kissed, caressed and gently played with one anothers breasts, ass's and thighs.
We were actually asleep naked holding each other when we heard our parents coming in drunk. We laughed at their foolishness, then reversed into a sixty nine. With our parents doing what they always did after arriving home drunk downstairs, fuck. My sister and I gave each other oral sex, right up until we heard mom and dad coming to bed. She slipped out of my room and entered her own, only to have me follow her a little later.
I slept with her that night, and most nights afterwards when we got the chance. We would often get into our position, ass to ass and watch each other lick our own pussies. And believe me being that close just made it all the more horny.
Over the years we carried on with our supple inventive way of entertaining each other, and pleasuring each others pussies too. She's now married and about to have her first child, yet it didn't stop us, right up to the point she could no longer get into the position, of having lesbian sex. Or as we called it "Sister sex".
I too now have a boyfriend, yet I know because we've spoken about it, if each of us still wants to after her child's birth, we're going to continue to enjoy our secret sister love.
