Now as for my sister. She knew what was happening with my cousin, my mom, and I. She did not judge but stayed out of it. I knew my sister masturbated a lot and had sex pretty frequently with her boyfriend when they were together but she hasn't been as open about her sexuality as my mom or I. She's never been as big on sharing a lot of details and she doesn't walk around naked in the hot summer months like my mom and I, though she does sunbath topless in the backyard (my mom and I have always done it naked) and she has skinny dipped in a secluded lake with us. She also can be vocal during sex and masturbation (not as much as my mom and I) and I've gotten myself off listening to her.
In the fall of 2021, my mom and I had been fooling around for almost a year and a half. About 2 months before my sister turned 19, we had a very long heart-to-heart about our sex lives. She told me she enjoyed sex with her ex but felt bad that she's only been with one guy. I told her she had plenty of time, when I was her age I'd only been with two guys (and 3 girls but I digress lol). She asked what it was like having sex with our cousin and I told her how talented he was. I even showed her some nudes of his I'd saved (I know he wouldn't mind) and she asked me to send them to her which I did. She asked about the threesomes with our mom and my ex. I also showed her his nudes, including some pics we'd taken of him and I having sex (one on one not the threesomes, and again he wouldn't mind). The real bombshell was her revelation that she's bi-curious. She has a best friend who she used to get naked and masturbate with, sometimes they would "practice kiss", and she always wanted to go further but never had the courage to ask. She told me she watches a lot of lesbian porn and even though she almost always felt guilty afterward she's even masturbated to the sounds of me masturbating and getting fucked. The nights of the threesomes with our mom and my ex she was a naked sweaty soaking mess from masturbating so much listening to us. During this whole conversation I was so wet. Sitting on her bed talking my bare feet had found their way to her cute little bare feet without me even noticing and we were reflexively just playing footsies while we talked. The hotter the conversation got I could see her nipples getting hard in her white top and I know mine were hard too. We eventually just wound down the conversation and I told her she could always talk to me about anything. We shared a very sisterly hug (sorta LOL).
A few hours later mom and I had really good sex. As we were cuddling naked afterward I saw I'd received a text from my sister that said, "I just came". I replied with, "If you're still up meet me in the bathroom." I excused myself from bed and walked naked to the bathroom. About a minute later my sister appeared... wearing her robe. I said I thought she'd enjoy seeing me in my sweaty naked post-orgasm glow for future masturbation material and I was hoping she'd return the favor and she laughed and apologized, saying she was naked in bed but threw the robe on to leave her room. She then thoroughly impressed me by dropping her robe. This obviously wasn't the first time we'd seen each other naked but it probably was the first time immediately after sex or masturbating. She's so cute. We shared another sisterly hug (this time naked) and I came so close to kissing her but I wisely chickened out. I told our mom about our heart-to-heart and she reminded me not to rush her with anything, which of course I'd never do.
About a week or so later my sister and I had another talk. We talked more about our sex lives, what we like in bed (even though she's only been with one guy), what we like to do when we masturbate. We both enjoy the taste of cum, even though I warned her boyfriend may have tasted good but other boys may not, my last serious boyfriend (before our cousin) didn't taste all that good. We both like to taste ourselves when we masturbate. I confessed my enjoyment of footplay and was surprised to learn that her boyfriend had played with her feet and sucked her toes a little and she liked it, which was a relief to me that she wouldn't think it was weird if I played with her feet in the hypothetical scenario where we might fool around. The whole time we're laying next to each other on her bed on our stomachs, I'm wearing a tank top and booty shorts, she has on a t-shirt and shorts, we're both barefoot and my toes are sliding up and down her soft soles. The more graphic our conversation gets the wetter I'm getting, and I notice she's starting to squirm a little, as if she was discreetly humping her bed. I decided to ask more about her friend she used to practice kissing with and masturbate with. She said it just started at a sleepover one night after talking about boys, they just stripped naked and did it. I had already told her that was almost exactly how it started for me with my first girlfriend, and that I'd already had sex with two girls before I even kissed a boy. I asked her if she missed having someone to masturbate with and she said she really did. So I sat up, took my top off exposing my bare boobs, and started playing with them. I said I really needed to masturbate and if she wanted to do it with me or if she just wanted to watch, I'd do it right next to her but if not I could always go back to my room. She said she'd like to masturbate with me. She took off her shorts and panties and laid on her back. For a moment I feared she'd leave her shirt on but as I slid my booty shorts down and off she pulled her shirt off over her head and I was overjoyed to see she wasn't wearing a bra. I took in the sight of her beautiful naked body (and she mine) before I laid down naked next to her. I felt her naked hip touching mine and it was heaven. My left foot found her right foot and our toes grazed together as I started playing with my boobs, warming myself up. She was doing the same only she had already started gently touching her pussy with her left hand. We both started rubbing ourselves and I finally got to hear her moans of pleasure up close instead of from down the hall. I was moaning too. I noticed she tends to only stroke her boobs and nipples very gently while I squeeze mine hard when I masturbate. Anyway, this continued for a few minutes and at some point both of us had gone from being on our backs to laying on our sides, facing each other. I don't know how close she was to cumming but I was almost there. In that moment, I lost control. Before I even knew what I was doing I lost control. I leaned in and I kissed her. She froze for a millisecond then returned the kiss. I was only the third mouth (and second girl) to kiss her mouth. I even stopped masturbating to cup her face, touching her cheek with my soaking wet fingers. At that moment she came. She had an orgasm while kissing her sister. It was one of the sexiest experiences I've ever had. After she came there were a few moments of very awkward silence. I started to apologise for making things weird (ok weirder) but she shut me up by kissing me again. As we kissed her left hand, which she'd been using to masturbate so it was covered in her cum, found its way to my boob and she groped it. That just made me kiss her deeper. We broke the kiss to come up for air and I told her I still needed to cum. I started fingering myself again and she pulled me in for another kiss and started touching my breast again. I had a massive shaking orgasm with my sister's tongue in my mouth and her hand on my boob.
We rolled back on our backs and just started giggling uncontrollably. And then the conversation started. I asked how she felt and she said she felt a little dirty but not guilty. I made it clear we don't have to do that again or go any further if she didn't want to. Long conversation later she told me what she wants. She doesn't think she could ever have sex with Mom, it would be too much psychologically for her. But fooling around with me somehow felt different. She also would like to have sex with my FWB if I didn't mind and if he'd be interested. She missed having a penis inside her. I told her I'd definitely talk to him. Then I asked her if I could try something. I told her to relax. I started kissing her as she laid on her back. After some nice soft kisses it started getting heavier and I cupped her boob. I started kissing down her neck and down to her boobs. I happily became only the second (and first female) mouth to taste her nipples. I thought about trying to give her a nipple orgasm because she had one once with her boyfriend (I guess it runs in the family, Mom and I have them too) but after a few minutes of sucking her nipples I started touching her clit. I was only the third set of fingers to touch her pussy (herself and her boyfriend) and I was honored. I started fingering her while continuing to suck her nipples, though I did start switching between kissing her mouth and kissing her boobs. She finally came hard and I kissed her through her orgasm. I licked my fingers and she tasted so good, sweeter than mom, about the same as me. Long story short she did the exact same thing to me. I was so worked up I swear I almost came when she first kissed my nipple. She fingered me off to two orgasms in a row and yes she tasted me.
We fooled around like that again a few days later, adding in mutual toe-sucking, and then that weekend I watched her fuck my ex-boyfriend and ate his load out of her. She went down on me afterward and she did pretty damn good for her first time. It's been a wild ride ever since
