Kim and Andy got back to the trailer just as the others were getting ready to shower. After John, Alice, and Sue left, Andy and Kim laid on his side of the trailer. They chatted for a while, of inconsequential things, and shortly after they slept, their arms wrapped around each other.
When the others got to the showers, Sue asked if she could join her parents.
"Andy and Kim have already showered and I don't want to shower alone."
John and Alice looked at each other and a signal passed between them. They smiled at Sue and welcomed her company so all three went into the family shower room and started to disrobe. Their household had never been overly bent on modesty but they didn't walk around nude either. The events earlier in the day had loosened things up a bit more. Despite that, when they first got in the room, everyone seemed a bit shy about disrobing. Alice took the initiative and shucked her clothes quickly to get first crack at the water. Chattering incessantly she lowered the tension and the others quickly joined her. They took turns wetting themselves under the water, then started soaping each other up. John was soaping Alice's back, paying particular attention to her shoulders, then her butt. Alice was soaping Sue's back, and when she got to Sue's buttocks she hesitated. Sue pushed her butt back a bit, so Alice continued and soaped Sue's cheeks, thrilled to be touching such beautiful buttocks. Alice's fingers lingered on her bottom curves and when Sue pushed back again, she delved deeper and soaped Sue's crack. Sue moaned when Alice's fingers softly touched her puckered hole and she pushed back more.
Alice had been intent on staying faithful to John during their separation and except for two one nighters with passing strangers she was able to resist other men. That didn't mean she'd gone without sex. She'd had a casual relationship with a married woman in town. It was enough to keep herself satiated, and it kept the other woman from otherwise strayed from the bounds of her passionless marriage. It worked out for both of them.
John could see what was happening between his sister/wife and their daughter and he was getting hard. However, he cleared his throat and when Alice looked at him he shook his head. She wasn't happy, but she acquiesced. Alice turned Sue around and told her, "I know I don't feel like your mother, but I am and we shouldn't be doing what I want to do. I want you sooo bad, but if we go any further, I would be no better than my Dad. So lets just keep it sensual."
Sue wasn't happy either, but she agreed. She started to soap Alice up from the front while John soaped her from the back. Then Alice turned around and started soaping John so Sue assumed her position behind him and soaped his back, butt, and legs. When it was Sue's turn Alice soaped her front while John, conveniently forgetting what Alice had already done, soaped her back and butt. Sue felt his cock when he stood up from washing her lower legs and she groaned. She instinctively put her hand behind her and grabbed his cock. All it took was a few strokes from her tiny soapy hand and he was done. He groaned and his cum shot all over her ass. Alice knew right away what had happened so she turned Sue around and dropped to her knees and licked John's cum off her ass and lower back. John was facing Sue now and the look of need on her face was hard to resist. She reached her arms around him and raised her face to his. She seemed to be studying him for a few seconds before she moulded her body against his. She searched his face as she moved closer, then her lips met his and her eyes closed.
John moaned into her mouth, his lips tentatively exploring hers. He felt torn as her tiny tongue probed between his lips and delved into his mouth. He knew on one hand that what they were doing was wrong. But his history with his sister and his adult daughter's obvious need had lowered his threshold so much that he was only left with the naughty thrill of their debauchery.
"Please Daddy," Sue implored. "I'm so horny, I need you." She pushed her pussy against his semi-hard cock, feeling the length of it slide between her moist lips.
"Baby, we can't. I want to so bad, too, but we can't. It would change our relationship. Maybe not in a good way." His cock belied his resistance by getting harder and his hips started moving on their own. His little girl's slippery cunt was right there, and she wanted it too. Then Sue felt Alice spreading her ass cheeks, searching out the last vestiges of John's cum, and Sue groaned and stuck her ass back. John took this opportunity to disengage with Sue. He stepped around her and reached for Alice who was crouched down. His cock was as hard as he'd ever felt it, and he stood Alice up so she was bent over at the waist. With no preamble he shoved his cock hard into Alice. She grunted at the force of it, and she stood up a bit and put her arms around Susie's neck. Sue and Alice kissed deeply and Sue tasted her father's seed on her mother's lips. Such a deliciously naughty moment and Sue was revelling in it.
Sue winced at the force of John's fucking. She wanted to feel it too, but she thought John was probably right. It was still intensely exciting to be supporting her mother while her father fucked her so hard. She put her hand down to her own pussy and started strumming her clit. John and Alice where making animal noises, lost in their primal lust. Sue could feel her orgasm building quickly, and it burst when she saw her father throw his head back and a grimace cross his face. He was unleashing his seed into her mother and somehow the thought of being there at that moment, a parallel moment to her own conception, was immensely arousing. Both women hung on to each other, gasping for breath while John fell away and sat back onto the wooden slat bench beside the toilet.
With everybody temporarily sated, they finished their shower in a sensual soapy massage fest. They all walked back to the trailer together and Sue kissed them both deeply before going their separate ways. John and Alice stayed up for a bit, holding hands and talking in front of the burning embers left over from the fire. It had been quite a day, but they were happy with the results of Alice's coming out.
It was dark in the trailer and Sue was chagrined to find the others had fallen asleep. She had cum, but she was still horny and needed someone else to help finish her off. All was quiet and she dimly saw Andy and Kim on one side, so she opted to take the other. After she crawled into bed she was restless. She tried to settle down but she tossed and turned, then she heard a voice quietly call her name. It was Kim. Sue sat up and turned on her flashlight. Andy was asleep, but Kim was gesturing her to come over. Sue got out of bed and crawled over Andy. Kim had moved over against the canvass, so Sue lay down facing her, her back to Andy.
"How you doin, Sweetie?" asked Kim.
"I'm happy. But I'm so fucking horny."
"I'm sorry. Andy and I were selfish, pleasing ourselves. We didn't think even of you."
"Oh no. That's okay.," said Sue. "I almost got Dad and Mom to fuck me, but they wouldn't. I watched them and masturbated, but it wasn't enough."
"God, that's hot. He's got such a nice cock. Almost the same as Andy's."
"It is! He came all over my back when I jerked him off, and Alice licked it off me and out of my bum crack."
Kim started kissing her, and while they were fully engrossed in what they were doing, Sue started to feel Andy's cock growing against her backside. He was obviously awake and he was getting hard. Sue felt her brother slowly shifting his hips, thrusting his cock along her ass crack. She reached behind her and stroked him a few times then she lifted her leg to give him access and Andy slipped inside, filling her up. He started slowly thrusting from behind while Kim slid down and started licking Sue's pussy. Every once in a while Andy would pull out and Kim would inhale his cock, then guide it back into her friends pussy.
"Oh God! Oh, it feels so good." Sue's body was trembling from her pent up passion. "Fuck me Andy, make me cum. Ohhh, Kim, that's it. Right there. Oh, eat my pussy baby. Lick my clit. Make me cum, darling. Oh, god! Here it comes! Oh! Oh! Oooohhhhh, aaaahhh." Her hips started jerking, her pussy clenching, trying to milk Andy's cock. Kim reached out and frigged Sue's clit. Andy grunted, sending his seed rushing into his sister's pussy. The truth was, they weren't too concerned with getting pregnant. He loved them both, and if they both got pregnant, he would be equally ecstatic. Kim crawled up and hugged Sue to her as her tremors waned.
Andy moved his torso closer and hugged Kim from behind. "I love you baby," he said.
Kim echoed his sentiments. "Yes, I love you too, Susie Q."
"Oh my god, I am so lucky. To have two such wonderful people love me." Sue gushed. She was bathed in the radiant love of her two soul mates.
They fell asleep that way and shortly afterwards John and Alice went to bed. They too were happy with the way things were going.
When Andy and the girls woke up in the morning, Kim found she was getting her period. She hadn't started yet, but she was crampy and bloated and not very happy but she was relieved that she wasn't pregnant. She thought she had better discuss her new relationship with her parents before something happened. She went and got some underwear to put on and put a tampon in. She was actually a little early this month but Sue told her having vigorous sex sometimes brought her period early too. She lay back down with the other two and they all quietly talked for a couple hours. They looked out the window and saw it was pretty dreary out. Cool and damp. Andy got up to get them all cereal for breakfast and found John and Alice up getting their breakfast.
