Note: The following story touches upon M-on-M sex; if not, your thing need not go any further. Save us both the grief.
Jack and Jen were always close, which seems to be the case between most twins. The odd way of knowing what the other is thinking and the strange world they seem to share. So Jack was heartbroken when Jen decided to go to college on the other side of the country. But he got it. Things at home were not good, and besides, she had the grades to go anywhere she wished to.
Jack, on the other hand, did not, mainly for not applying himself, choosing to chase tail instead and seemingly never finding what he was looking for. Jen only came home one time during her college years, and that was for the funeral of their parents, who died in a car accident, and there was little time or mood for anything else. Then, during her final year of college, she met Clark, and their plans to marry soon followed.
It seemed like the Twins may never see each other again when Jen confessed her plans to stay on the East Coast, where Clark was a local. He already had a wonderful home left to him by his parents, and, more importantly, a great job offer awaited him. It wasn't until three years after they wed that Jen announced their plans to come out and visit him. Strangely, this was good timing as Jack finally found a job he enjoyed and, from that, a life he was proud of. He had just bought his first home, so things were looking up for him, and he was excited to show his recent success to his sister.
Their flight came to town late, so there was little time to visit before bed beckoned them all. Even though the following day was a Saturday, Jack, now in construction, was up before the sun. He was expecting to be the only one, but as he walked past, he heard moans from the guest bedroom. And that made sense as it was three hours later to them, East Coast time. But now closer, the moans seemed not as he expected, sex but those of pain.
Jack stopped at the door and listened in an attempt to understand, not seeing the door was slightly ajar, and it opened with the lightest press upon it. Jen's eyes went straight to him, and although Jack felt a bit embarrassed, Jen just smiled and continued to massage Clark's back, seemingly giving him trouble. Jen was naked, her breasts swaying back and forth, but nudity between the two was never a problem, hence no effect on either of them. While searching for the right job, Clark did a stent at a Day Spa where he trained to be a masseuse. That training kicked in, and Clark drew closer, saying, "You need to push harder."
Jen: "l am; I'm pressing as hard as l can. Come help me."
Clark: "Ah, l don't think so."
Jen: "Stop that. Do you want to feel better or not? After all, we're family now."
Jack slapped his hands together to warm them, and as Clark was already oiled up, he went straight to work. Within a minute, Clark's moans of pain became those of pleasure under Jack's schooled hands. Clark's back squared away, Jack moves to the foot of the bed and starts in on Clark's feet, knowing there is so much stress held there. He didn't notice with all the activity that his robe fell open, but seeing the other two were nude, it wasn't a problem, not even when he spotted Jen eyeing his rock-hard cock. "Enjoying yourself, brother?" Jack was at a loss until he followed her eyes, finally noticing that at least his cock was in good spirits.
Jen always had a sense that Jack was Gay or Bi at a minimum, but such never mattered to her; he was her brother and best friend. But for the first time, it affected her. Seemingly confirming her opinion, and now, with her husband causing such a reaction, she was quickly losing herself. As Jack moved up Clark's legs, Jen leaned against the headboard, parting her knees to finger herself as she watched.
When Jack filled his hands with Clark's firm butt cheeks, he finally gave in; the pleasure was too much to bare even for a straight-as-an-arrow guy.
Clark: "Fuck yeah, that feels great."
Taking that as permission and maybe to please his sister, Jack slipped his hand between Clark's cheeks, stopping and lightly pressing at his back door. Clark tightened for a moment, then relaxed to the now-welcomed attention. Now Jack held an even pressure and waited for its response, Clark, as expected, pushed into it, allowing his digit to enter his virgin ass. Jack looked up and smiled at his sister, who was fully aware and now covered in her cum.
Jack removed his thumb to the sound of Clark's disappointment, and then he applied a sounding smack across his ass.
Jack: "Okay, now turn over."
Even after saying it three times, it took Jen's insistence before Clark finally did, maybe because of the ragging hard-on he was now sporting. Jack, sensing such, Informed Clark that it was normal and proof he was doing a good job. Doing so seemed to relax Clark some, which allowed things to move forward. As Jack massaged Clark's neck Jen moved in to help, she oiled her hands and went straight for his cock. She pulled and twisted as Jack did the same to his own, as the other hand remained focused on Clark.
Jen changed things up and replaced her hands with her lips, engulfing Clark's manhood, or trying to anyways. After a few failed attempts, Jack and just maybe Clark, too, had enough.
Jack: "Out of the way, Sis, let a professional show you how."
With that, Jack moved over Clark, and in one swoop, he took Clark balls deep; Clark's response was what one would figure, and he wasted no time in fucking Jack's warm mouth bobbing over him.
To the delight of both Jack and Jen, Clark started to flick his tongue at Jack's hanging balls just above him. Jack wormed Clark's legs up, presenting his backside to Jen, who was biting at the bit to join in; she wasted little time before tonguing her husband's ass. All of this proved to be too much for Clark, who pumped his salty load into Jack's wanting mouth.
Jack would have been happy to end things there, but Jen was far from done.
