Mary woke up the next morning and found herself being spooned by her son Mike again. She smiled, remembering the night before and she felt a delicious tingle in her cunt. She wiggled her ass against his hardening cock then moved away just enough to place it between her thighs.
Mike stirred and moaned, “oh god mom! It wasn’t a dream?”
“Yes honey it was a dream come true! It was just too wonderful and why haven’t we surrendered to our obvious desires before this?”
While she was talking, she continued to move her hips, causing a delightful sensation for both of them. She then reached between her legs and guided his cock into position then pushed back, moaning as his cock sank slowly into her steamy tunnel. Mike started a nice slow fucking motion, “oh god mom! I can’t believe that I’m fucking you again!”
“Yes honey! You’re fucking me so good! I love your cock in my cunt! Fuck mommy hard! Make me come!”
Mike was only too happy to oblige. He pushed in hard, feeling the bottom of his mom’s cunt stretch.
“Oh god honey! Oh god! You’re deep! Oh god yes! Harder! Please! Oh my god! Please!”
She had never felt a cock as big as her son’s. Her husband was only around 5 inches and Mike must be at least 7 or 8!
Every time he jammed his cock in hard she made a grunting sound, “mmmph! Mmmmph! Mmmph!” He was going faster as his lust took over, no longer trying to be gentle.
They were both sweating and when their bodies slapped against each other it made a wet sound that mixed with the sloshing sounds of her very wet cunt as his cock sawed in and out. The smell of sex was strong as they neared a mind shattering mutual orgasm.
Then it hit them at the exact same moment. A strangled moan erupted from Mary as her limbs began to shake uncontrollably. She pushed hard against her son’s cock as she felt his cock swell and start to spurt long ropes of cum deep into her cunt! She thought she would never stop cumming, but finally her orgasm began fading to a pleasant buzz in her cunt. Mike’s cock was now just oozing cum into her well fucked cunt.
“Oh god Mike! How can I go back to fucking your dad? He never makes me cum anymore.”
“I don’t want you to fuck him anymore! I don’t want you to fuck anyone but me!”
She pulled away from him and turned quickly, cum gushing from her cunt. She pulled him close and passionately kissed him.
“Well, I don’t know if I can promise that but I promise I won’t without your permission.”
He could accept that.
They cleaned up and had breakfast in the suite. When they were done they put their swim stuff on and went to the pool.
After they swam for a bit they found two lounge chairs that were empty. After a few minutes a man around Mary’s age and young girl sat next to them. He introduced himself as Rick and the girl as his daughter, Nan.
She appeared to be 15 or 16 and very attractive. He explained that he was divorced and his wife was not in the picture. He and his daughter needed a vacation and decided on a cruise.
Mary explained why her son and her were alone on the cruise.
They became very friendly and decided to meet for supper. Mary invited them to have dinner in their suite. She told them it would be more comfortable but the real reason was that she wanted to see if they had the same kind of relationship that they had.
At 7, Rick and Nan arrived at the suite. Mary was again stunned by how beautiful Nan was. She had large breasts for her age, at least 34c. And a nice flat tummy, exposed by her crop top. She was wearing a tight miniskirt that showed off her long shapely legs and firm, peach shaped ass.
She was hoping she would see more of her as the evening progressed. She wanted to see her under Mike with his cock buried in her tight little cunt.
She turned her attention to Rick. He was tall, at least 6’5”. She hoped that his cock corresponded with his height.
They picked items from the room service menu then talked while they waited for the food to arrive.
Mary started the conversation. “I really admire that you and Nan seem to have the same kind of relationship that Mike and I have.”
“Thanks Mary, we became much closer after my wife left us. It really devastated Nan and I wanted to be there for her.”
“Well, Mike and I have always been close. My husband travels extensively with his job so we have been left alone a lot. But this cruise has brought us even closer.”
Rick raised his eyebrows at that and looked pointedly at the bed. “I see there is only one bed in the room. Does Mike sleep on the sofa?”
Mary knew what he wanted to know and wasn’t going to beat around the bush, “no, Mike, he sleeps in the bed with me, does that shock you?”
“Well, do you do more than sleep?”
Mary smiled coyly, “I think you know the answer to that.”
Nan was wide eyed listening to the exchange. She looked from Mary to Mike, trying to process what she just heard.
“Are you shocked by that?”, Mary asked Rick.
“No, actually I am turned on by it.”
“So Rick, do you and Nan have that kind of relationship?”
Nan spoke up, “No way! He’s dad! I don’t know if I could do that!”
Mary probed, “Are you telling me you never thought about it?”
Nan turned bright red. Rick looked stunned and asked her, “Really Nan? Did you?”
She put her head down and nodded.
Mary pressed the issue. “And have you thought about it, Rick?”
Nan looked at him, waiting for his response.
He looked back at her, “Yes.”
Nan was breathing deeper as she looked at her dad, her desire evident.
Mary was delighted that she had been right about the two. She told Mike, “come sit with me Mike and we’ll show Rick and Nan how much we love each other.”
Mike sat next to Mary and they kissed, open mouthed and passionately.
“Oh god! This is so hot!” Nan uttered.
Mary took Mike’s hand and put it on her boob. Then she started to rub his cock through his shorts.
She pulled away from the kiss and told Rick and Nan, “why don’t you join us? I know you both want to, and the bed is more than big enough for all of us.”
Mary rose and walked over and took Rick and Nan’s hands and led them to the bed.
Rick looked at Nan and asked her, “do you want to do this honey? If we do, we can’t go back.”
Nan looked at her dad with love and desire, “yes! Oh god yes! Kiss me dad! Make me your woman!”
Rick wrapped his arms around his beautiful daughter and their mouths met, opening in a passionate tongue kiss. Rick stepped back and pulled her tee over her head. She wasn’t wearing a bra and her boobs jiggled as her tee raked across her nipples. Rick bent down and took one of her nipples in his mouth.
“Ohmmmm, yes daddy! Oh yes!”
Rick switched to the other boob. Nan was moaning as her dad sucked on her nipples. While he was doing that, he unbuttoned her shorts and they dropped to the floor. She helped him pull her panties off then fell back on the bed.
Mike and Mary had been watching, but they were getting too horny to not join in. They went to the bed and pulled their clothes off, laying together next to Rick and Nan. They watched as Rick took his clothes off. His cock was hard and long, longer than Mike’s. Mary was panting hard, anxious to see it stretch Nan’s tight twat!
“Oh god! This is so fucking hot!” She moaned. She was stroking Mike’s cock as they watched.
Rick laid next to Nan and resumed his oral exploration of her body. He kissed down her torso until he reached her clit. When he sucked it into his mouth Nan moaned, “Ohhhhhhhhhhhhh god! Oh yes daddy! Ohhhhhhhhhhhhh yes!”
Rick sucked hard on her clit while using a finger to find her tight opening. He pushed his finger in just past the opening. He felt her hymen and was excited to know he would be the first to fuck her. He pulled out and asked her, “are you ready?”
“Oh yes daddy! Do me! Please!”
Rick laid on his back, being so much bigger than his daughter. He lifted her on top of him and reached between them. He rubbed her pussy with his cock head until he found her core, then he let her weight slowly impale her on his cock. He felt her hymen tear as his cock penetrated her. She whimpered and he said, “do you want me to stop honey?”
“Ohhhhhh no! Oh god daddy! It feels so good! I can’t believe it! You cock is inside me! More! Put it all in there!”
He pulled her down and his cock sank in until it wouldn’t go any deeper.
Mary and Mike couldn’t wait any longer. Mary mounted Mike and his cock sank easily to the hilt.
The two incestual lovers started to fuck, watching each other to increase their passion. The room was filled with the sounds of passion and the smell of sex. Mary started to twerk on top of Mike and Nan tried the same movement.
“Oh, holy fuck! That feels amazing!” Nan moaned as she moved her hips rapidly on her father’s cock. It was almost all the way in but it was too long to go all the way. He was pushing at her cervix and she moaned each time she slammed her pussy down on his cock. She felt like she started cumm8ng as soon as his cock penetrated her virgin cunt! It was building rapidly as she felt his cock spreading her cunt then pulling back only to spread her again. Rick was also nearing an orgasm and he didn’t want to cum inside her. He used all his techniques to delay his orgasm, hoping that none of his sperm would leak into her. He was about to give up and pull out, unable to hold off any longer when Nan started to jam her cunt down harder, stretching her cunt until he was buried all the way.
“Ohhhhhhhhmmmmmmmmpppphhhhh!! Ohhhhhhhhhhhhh yes! Ohgodyes! Yes!” Her orgasm was so intense that she got dizzy. It was impossible for Rick to hold out and he moaned, “Ohhhhhh no! I can’t hold it! Oh fuck! I’m cumming! Oh god honey! Ohhhhhhhhhhhhh god!”
He tried to push her off but she held onto him, not wanting to let his cock leave her cunt!
“Oh daddy! Oh yes! Cum in me! Make me pregnant! Oh God yes! I feel you cumming in me!”
Mary and Mike were so turned on by the lewd display that they started to cum!
“Oh god yes! Cum in her teen cunt! Knock her up!” Mary moaned as she came, feeling Mike’s cum jet into her!
All four of them finally calmed down but stayed in the same position.
“Oh daddy! That was awesome!” Nan moaned as she held her dad’s cock inside her.
After they caught their breath, Mary suggested, “why don’t we switch? I’m sure the two teens would love to fuck each other and I’m dying to get that big cock in my cunt!”
Mike looked at Nan and asked, “do you want to? I’d sure love to make it with you!”
Nan nodded and Mary got off Mike, letting Nan climb on top of him. The thought of fucking this hot young girl had his cock hard and ready. Nan guided his cock into her and he sank in quickly, her cunt lubricated with her and her dad’s juices.
Mary climbed on Rick and managed to get all 8 inches of his cock inside her.
They watched their children fuck each other as they fucked.
Nan was again twerking and Mike was pushing up against her thrusts, both kids moaning as they released their passion with frantic motions, feeding off the taboo nature of what they were all doing.
The room was again filled with fucking sounds and smells and the lovers lasted longer this time, but it was too much for Mike and Nan. They both started to cum at the same time, Mike filling her already sopping cunt with his sperm.
That brought Mary and Rick over the top and the slapping of wet cunts and cocks filled the room until all four fell together, exhausted.
During the rest of the cruise Nan and Rick spent almost all the time in the suite. They guys fucked the girls, then watched the girls suck each other’s cunts. They fucked in every imaginable position.
When they returned to the port, they arranged to meet regularly.
Mary divorced her husband and a few months after the cruise when the four met both couples announced that the women were pregnant.
