So, there were intense discussions on how the reproductive cycle worked for these magnificent trees. By the way, the exploratory colonists were having a hard time thinking of a proper name for them in Latin. Familiarly, they were just called Big Trees and everyone knew what was meant by that. In the meantime, the couples were very organized in their living arrangements and study responsibilities of the doggystyle planet. But there was plenty of time for sexual fun, because entertainment was curtailed to them for the present to not subvert their pure convictions of what they were seeing and studying. In their initial design they were made to be intensely sexual to tap off any boredom or other stressful feelings that they might have. And though they understood that they would not have children right away, they pretended that they would, both in their vaginal sex and in other sex as if they were ducking the issue. Anal became very popular among them because of its slight amount of kinkiness. And Oral became very prevalent among them, for the same reasons. But when the mood would hit them cum (and it was often) they would seek privacy for their expressions of lust to each other. Somewhat of a curious action on their parts, because it had not been programed in them. But it was very firmly held to. However, on the first day of an extended up close and personal study of the Big Trees, a couple whose abilities were compatible, but their partner matchups were with others; found themselves in an embarrassing situation under the trees. It was found that the Big Trees put out some kind of sperm emanation and sponsored a surrounding aura, that made sexual union a powerful mental goal, whether the couples were paired or not. The first couple to experience this were in the course of their studies of one particularly large specimen of the trees, when they came out of a mental stupor with his cock up her vagina spewing out his sperm laden semen. Not that she minded at that minute at all, but it left some serious explaining to their mates that night and a wonderfully inspiring sight to anyone that had happened to see the video of it. From then on, the pairs to study were made of dedicated couples, and if an unmatched one needed to be used, everyone just looked other way and the actual mates took no notice. Especially if the guilty mates, made up for it that night in bed. Later the A.I. allowed the two to view the video of their experience, in the name Hardcore of science, of course. The A.I. had been recording all of their activities on the planet from the very first, to watch for developing anomalies. So, the video showed the unmated juicy couple as going about their scientific exercises when all of a sudden, they stood up rigidly and threw off their clothing (But kept their shoes on.) Then with glassy eyes apparent from the closeups generated by the viewers, they moved together and with a lot of kissing and close quarters caressing, he got his penis mounted up against her pussy cleft and clit, one of his hands on a breast, one of hers across his back pulling them together and their lips welded together with active tongue play. Not terribly unusual, except for it not being a mated couple, and they were mentally evidently unaware of their sexual interchange at that time. As her vagina lubed up, even more than usual, he moved down to sample its taste, and she soon did the same of his member. Then she guided him to be upright and she moved his cock to penetrate her vaginal entry, with her hunching down on it. Soon, with her complete and utter welcome, he emptied up into her and they then came to a stunned recognition of what had just happened. One of the anomalies that was observed was that in addition to the emanations that were evidently guiding this through the female, the trees showed evidence that they were enjoying the process and the viewing of it working out. Just a suspicion clit of this, but likely. After about a month of their habitation on the still unnamed planet, some changes began to be noticed in the Earther females and males. The men’s arms began to lengthen, their penises began to lengthen to eight or nine inches and their bodies began to grow up with a slight thickening. Not that their mates minded at all. Also, the women, along with the men, began to take on a greenish tint to their skin coloring along with their eyes. And their bodies began to stretch up and their arms also got longer. Their hips area began to widen out somewhat and their vaginas were constantly lubed up for action. Their sexual appetites surged up too. It was determined that the sponsor of these changes was the biotics in the air that were not being completely stopped by the air filters which were not fine enough. It didn’t help, either, that the personnel became somewhat lax in their use of the filters. These changes brought about other changes, too. For one thing they overpowered the bodies protocols for nonpregnancies. After a six-month sojourn on the planet, all of the women found themselves to be pregnant. And of all things, what was produced was not babies as we know them, but leathery eggs with a baby’s embryo inside and it was laid by the mothers at the four-month stage of the pregnancy. Warrick lifted his daughter up once again, and Ivy chased after Brie’s pussy, up Warrick’s cock, with her tongue, slurping up all of the sticky juices that the girl left behind. Watch me, I thought, much to the dismay of my conscience, fill your eyes cum with my depravity. After a very thorough discussion about Mike's obsession with piss, she asked what else Mike was interested in sexually. When she saw him she smiled, pushing a strand clit of hair behind her ear, and strode towards him, leaving her suitcase on the path. Then she said when you call in a order from now on to ask for her. “Damn, I would love a crack at that lesbian.” I walked over to her leaned down and started the shower, when I felt it was warm enough I got in the shower and drew juicy her in with me. She got in the sperm tub with me and I turned her around so that water was hitting her back. Ronja stared at him in disbelief, but then moved to block him from leaving. Her breasts were noticeably bigger than I remembered. I groaned, squirming on the bed. Then doggystyle again, most porn I watch is just animalistic or primal. His black bush of chest hair always spilled out from the top of his unbuttoned polos, and when he lifted his shirt to scratch, a thick trail of it went down into his pants. You're doing such important work.” The front of his robe was beginning to tent out, and she knew what was responsible. Most of my friends know I write recounts of my past sexual experiences like what im currently doing to whoever is reading these stories I told Amy I finished a recent story about me and her and asked her if I could read it to her. Gerard approaches his sub and gives her a slap onto her breasts, through the jumper! Now things were getting more interesting 2 boys 2 girls and Kim being older and wiser, haha. I think it comes from being on the swim team. The Orcess looked around and found, surprisingly, a few humans willing to meet her gaze, their expressions uncertain, but curious. I didn’t know until I was in college just how much I was like my Dad. In his moment of ecstasy I shifted quickly to put my hand in my pants. He had his cock out and it slid smoothly into Laura's wet pussy as she lowered herself onto him. "Why are you doing this to me..." After eating her pussy like a wild animal eating meat, she took my head off by grabbing my hair she squirted. He wasn’t losing Jenni Hale because he never had her and if she was like most girls, she probably didn’t know how to use that pretty little mouth for anything worthwhile. She squirmed as I licked her anal cavity. He needs some sex as well," she says laughing about her John Hardcore comment. They were safe.
