I am happy to share my stories. But, French of origin, thank you for your understanding for my English which remains very imperfect!

In every family there are somewhat stupid traditions. In mine, it's the one that happens around my birthday. I should say our birthday, because I have a twin sister, Patricia: we all call her Pat.
"Doudou, did you remember to take everything?!" My mother shouts to me from the entrance hall, as I finish filling my sports bag in my room. She keeps calling me Doudou, even though my name is Edouard and everyone calls me Eddie.
My parents are pretty nice. But, since their wedding anniversary is at the end of May and Pat and I were born on June 1st, they insist that we organize a family weekend around the first rugby match which takes place in June. Clarification: I have been playing rugby since the age of 6 and am in the Grenoble junior team; my sister is a cheerleader.
The day after tomorrow, Sunday, my team plays in a regional competition in Clermont-Ferrand, 150-160 miles from here and we leave this Friday late afternoon to spend the weekend in a cottage above Clermont-Ferrand to celebrate there our birthdays and anniversary.
The worst part of this tradition is that my parents insist that we do what we liked to do in the old days: travel dressed for our respective sports! When I tell you it's a stupid tradition!
Especially since we are no longer children! At 19 years old (5 days ago!), I am a solid boy. Not very tall (around 6'), rugby made me gain quite a lot of muscle without it being excessive either (I weigh 180 Lbs, with a flat stomach!). I'm pretty cute, brown with short hair and especially blue eyes that attract girls. I'm quite successful with them, perhaps also because I'm lucky enough to have a cock that they like (8'' x 5.5'': that would be the ideal size from what I have understood; not too big so as not to tear them, not too fine so that they feel it filling them!).
"I'm delighted to be leaving for this weekend, as we have been doing for so long! Not you?" My mom asks us as the car leaves our house. My dad who drives of course approves. My sister and I agree without much enthusiasm.
Another new family tradition: my father, who recently discovered an environmentalist streak, decided to avoid driving on the highway, so we take the secondary roads! To go to Clermont-Ferrand it will take us at least 4 hours. Needless to say, my sister and I, despite the comfort of this spacious Audi A8, are not the happiest.
"I'm going to take advantage of the trip to get some sleep." Pat tells us, moving closer to me before lying down, head against the door and knees bent.
For my part, I scroll on my phone. After a few minutes, Pat moves a little and I'm completely hallucinating: her cheerleader mini-skirt, which already doesn't cover much, has risen up and she hasn't... put on any panties!!! My sister shows off her vulva and the crack of her buttocks without any shame! To her own brother!
It's even worse than that: a sort of yellow handle comes out of her pussy; it moves on its own, or rather with the contractions of her vagina!
I'm all red in front of so much immodesty. But the situation worsens when she opens her eyes and smiles at me when she sees where my gaze was fixed, because she takes this yellow handle to almost completely remove this banana-shaped and quite good size dildo. Then she pushes it in again with a slight wet noise... Her pussy seems to be well lubricated with excitement!
My parents don't see or hear anything: they chat among themselves, talk about the good old days when they were young, all with music from the 90s in the background. Luckily for them!
For my part, I have already had to deal with quite a bit of provocation from my twin.
It started when we started college last September. Is it because of her 18th birthday, her arrival at college or her new acquaintances? I no longer recognized the sister with whom I had until then a smooth, complicit and pleasant relationship. But overnight she decided to have sex with... me! Except that, me, even if I'm never the last to take out my cock when there's a cunt to visit, I don't want to do it with my own sister!
At that time, her provocations were endless: entering the bathroom when I was in the shower, opening my bedroom door ajar when I was watching porn while jerking off, picking up my dirty boxers to sniff them and find the gooey results of my hand-jobs, spying from outside through my bedroom window the few times I brought a babe home to fuck her...
Then things finally calmed down at Christmas time after a serious incident. One morning I wake up in the middle of an erotic dream where I was having my cock thoroughly sucked (quite a common dream for me!): so, I decide to take advantage of it to take care of my morning wood and release the pressure in my balls... When I pull back the duvet, I discover... Pat! And I understand that what woke me up was not a dream, but my naked sister sucking my cock!!!
It made me so angry that I violently grabbed her arm to get her out of my bed. As I went a little hard, I sprained her left wrist! Of course I didn't do it on purpose, but it had the effect of calming her down. Plus a few days later she started dating with one of my rugby buddies, a well-hung guy to fill her pussy and therefore calm her hysteria!
Back in the car on the way to Clermont-Ferrand: I see her vulva contracting and the banana tending to be expelled. It slides so well in there that the dildo finally falls onto the seat. To prevent my mother from seeing this big, sticky yellow banana on the black leather seat, I take it and put it back where it came from. Pat moans and puts her hand on mine and moves that dildo back and forth: I should never have touched that thing!
Firstly because it excited my sister! But also because it woke up my cock and my libido. And when I'm stiff, nothing can get my cock back down except a good handjob!
After a few back and forths, she removes the banana again and she sticks her tongue out at me, then inserts the dildo into her luscious mouth. With her other hand, she takes my right hand and brings it closer to her twat from which a trickle of her juice flows out. Without really knowing what I'm doing, I stick my thumb in: it's very warm, very soft and very moist. As it is well dilated, I remove my thumb to now put 3 fingers there (and for the record, I don't have little fag fingers!). Pat moves her pelvis so that my fingers go deeper...
I withdraw my hand to smell the scent of her intimate fluids: real nectar! This has the effect of immediately making my cock stand at attention: I readjust my shorts, before plunging now 4 fingers back into my sister's horny pussy: she releases even more juice. She moans discreetly. I take my hand out and massage her clit: she squirms with pleasure on the seat while sucking her banana. For several minutes, I alternate between 4 fingers in her wet pussy and my stimulation of her clit: at this rate, Pat is quickly seized with convulsions and even releases an ecstatic sigh!
