[Open to removing the incest angle]

Our parents are wonderful people who have dedicated their whole lives to traveling the world to solve its problems for as many people as they can. That's been our whole life with them, from infancy, traveling with them, living with them, often joining them in their causes. We've dug wells in Asia, distributed mosquito nets in Africa, built granaries and cereal banks in impoverished parts of Europe, passed out food in US cities laid waste by drug epidemics.

We're less than a year apart, which surprises people, but...well, that's Mom and Dad for you. They love each other dearly, and they've been excellent models for their children in how a couple should treat each other.

If only their children could actually meet other people.

As wonderful as our lives have been, now that we're both in our 20s and doing online university courses as we travel, we're starting to feel the lack of socialization. Oh, we run into other people all the time, we even have a few friends we've kept up with over the years. But forming long-term, romantic relationships? Not really possible. We've each had little flings, some feverish and even passionate whirlwind romances while stationed at a mission or an NGO base for a few weeks, but nothing that might be considered fulfilling. Certainly nothing with a future.

If we want something like what our parents have...we'll have to turn to each other as the only constants in one another's lives. That's something we eventually realize as we discover that the temporary relationships we try simply fail to satisfy our need for something more real.

It starts slowly, and more or less innocently. We've had to share tents and hotel rooms and even beds in the past, huddled together in a sleeping bag on the Siberian steppes or lying on the cold tile floor of a hostel, sweating gently in the Sudanese heat. Riding hip-to-hip on airplanes of all sizes, or with you in my lap on bumpy roads. We're used to our hands being on one another's bodies, at least through our clothes, and we're used to being close. We just...get a little closer at first. A hand on your thigh as we ride through Mongolia in the back of a taxi. Your arms wrapped more tightly than necessary around my waist as I drive us across town on a scooter in Taiwan.

We test each others' limits. Do you really need to wear a bra when we're sharing a hotel room, one strap of your tank top falling down your arm as you study with your legs crossed on the bed? Do I really need to sleep so close to you, my hips pressed up against the feminine swell of your ass? Did my hands press up under your shirt to rest on your stomach by accident last night, or was that a deliberate move on my part to seek out a closer touch to the one beautiful and perfect woman who is constant in my life?

I'd like to play us growing bolder as we travel, teasing each other with outfits and touches, escalating out of playful rivalry and curiosity. "Oh, that feels good...can you keep doing that?" as my fingers trace over your nipples through your shirt one night.

"Mmph... stop, you're not making it any better," I complain as you gyrate your ass against my crotch in the back of a taxi, trying not to chuckle at my discomfort as you jostle my growing erection.

"You don't have to stop," I whisper to you when I hear the quiet gasp that tells me you've realized I'm awake and can tell you're masturbating late one night.

"Can I...feel it?" you whisper two days later, when I'm obviously erect in the seat next to you as we ride in the back of the mission van up a bumpy road in India, and your small hand snakes over my thigh to caress the bulge in my light cotton shorts while I bite my lips and look out the window.

We don't cross all the lines at once. We do try to hold back. Handjobs and blowjobs are just for relief, right? To make things easier and more relaxing? And you just cum that much more easily on your brother's thrusting fingers, especially when he does that thing with his tongue on your clit at the same time. It's not really sex if I'm mounting you but only fucking your thighs, right?

Come and join me as we travel the world together, and go on a personal journey all of our own.

Kinks to include could be touching, groping, teasing, oral, fingering, escalation, cumshots, creampies, facials, outercourse, handjobs, titplay, light bondage, and lots and lots of passionate fucking. If straight incest isn't your jam but you like the premise, we could adjust our relationship, too.

Limits are impregnation, scat, watersports, blood, and heavy BDSM.

PMs only please, I don't do chat. Discord's an option.
