We slept in one big tent, the four of us side by side. It was a routine trip, one we had done many times before. Hardcore When we arrived at our remote haven, we went to work immediately cleaning up a few months of neglect and storing our new supplies. That night as the mosquitoes buzzed nosily around us dad told Tina and me we would stay in the shed next to the main cabin. Before we had always slept in the main room on cots near our parents but now he was missionary telling us that we would be apart, he and mom in the cabin, Tina and me in the shed. Neither of us were too annoyed by his announcement, the shed was actually nice and cozy and there was plenty of room to turn it into a split bedroom. It was what mom japanese next said that changed the rest of our lives. “Tina, Von, listen carefully, your dad and I have been talking this over and we think that it would be a good idea if you two shared a bed, to become intimate. You’re both old enough and by being together you will be able to avoid the turmoil and unrest that happens to sexually mature people when they don't have physical outlets. That's why you will be in the shed this trip, for the privacy.” Tina bolted up from where she was sitting and looked down at her, “What!? You want me and Von to have sex? Mama, he's my brother, he's younger than me, we shouldn't be doing that!” I sat there too stunned to move or say anything so I let my sister vent our like-minded objections. Mom looked at dad to take over, “Tina, you have both grown into strong, healthy young adults. That the man is younger than the woman has no place in the sex act, that's not a valid argument. As far as being brother and sister, out here that won't matter; once you get over that little hiccup we think you will find that sex can be just as satisfying as with a non-related person. The only thing you have creampie to be careful of is having a baby and that shouldn't happen, that's why your mother took you to get birth control last week. It wasn't because of Marty; it was because we know that you two are ready for this final phase of growing up. When we have to move out here permanently we want you to be fully prepared, to be able to stay here alone if you have to and not antagonize each other in sexual frustration. We don't want you two to be afraid of each other or of being alone together. There may not be anyone else around to trust for some time.” Tina and I were both too staggered to say anything as our mother took over, “We aren't going to force you two to couple, we suspect that will happen naturally once you get used to the idea. I can see that threesome neither of you want to do this, but from now until we go back home you have the shed, what you do in there is up to you. Goodnight kids, dad and I are going to bed.” Seconds later I was alone with my sister beside the campfire. I looked at Tina “What are we going to do?” I asked bleakly. When they knocked on door 8 it swung open instantly. “Yes, we are,” I moaned creampie as I missionary moved up her body. One “God” made all his daughters into his harem, japanese threesome another made his older sister crawl naked through his college, talking about how she was her brother's slut and deserved to be punished. My hands squeezed her hips. I couldn’t help but laugh when she declined. The yoga pants where comfortable to wear, but the fabric went into his buttcrack and around his junk, making it impossible to hide a potential boner. A bead of sweat ran down her dark skin. Her eyes were bulging out of her head, tears were streaming down her face and she looked terrified. “It is quick, but I’ve never been more certain that it’s the right thing for both of us. “Yeah, that happened too. It's been fun. It sounded so genuine that I almost jumped off the bed as if I had heard it from a cobra. I was so proud of my sister for thinking on her feet like that. So we worked out which rings and ropes we would use and then he covered my body from neck to waist in vaseline.
