Jane then pulled down the swim trunks that covered Adam's lower body.
As soon as they came off, his semi-erect cock popped out into the open water.
Right away, Jane wrapped her fingers around his shaft and began stroking it.
Within seconds, the blood flowing into his cock made it swell to its full length.
Adam's hands moved down to grab Jane by her ass cheeks. His fingers dug deep into her skin, squeezing and kneading her firm buttocks until they turned red from his strong grip.
'God... Her ass feels incredible!' Adam thought as he continued feeling her soft, plump backside with his hands.
Jane let herself float closer towards Adam while maintaining a firm hold of his erection. Then, she turned around and pushed her bottom towards him, aiming his cock between her legs.
Seeing this, Adam took the opportunity and shoved his cock deep inside Jane's pussy, making her arch her back and grunt as he penetrated her in one swift thrust.
'Aaaaahhhhhh!!! This feels even better than I thought it would. Having sex underwater is way more fun than what I imagined!' Jane cried out within her mind as she began moving back and forth on Adam's cock.
Each thrust of his shaft caused waves to move through the seawater around them, creating a force that made their movements become even more erratic.
'Ohhh... god... It's so good! Fuck me harder, Adam!' Jane exclaimed mentally as she tightened her muscles around his dick.
Adam grunted from the intense feeling of her squeezing his erection as he pushed deeper into her, pressing his pelvis against her ass cheeks.
He grabbed onto one of her breasts from behind to hold onto it while thrusting faster inside her pussy, causing bubbles to form and float up towards the surface as a result of their fucking.
Meanwhile, Jasmin was left feeling somewhat ignored amidst all these sudden sexual activities going on around her.
However, she wasn't about to allow herself to get left out of everything.
So Jasmin swam closer towards her nephew, Oliver, who was still humping away at Mia underwater.
As she approached them, she reached into Mia's bikini top and grabbed her right breast.
Her fingers teased the nipple while Oliver continued his thrusting into Mia's cunt, which made Mia's breathing rate quicken and her whole body shiver from all the sensations overwhelming her.
'Mmmm.... It feels so good... I want more.' Mia's thoughts flowed through her mind as she enjoyed being pleasured by Jasmin's hand while being fucked by her son underwater.
Soon, Mia couldn't resist it anymore, her pussy tightening around Oliver's cock while she screamed in ecstasy inside her head. 'Ooooohhhhh! OOOOOH!'
Oliver felt her inner walls clamping down around his penis, so he thrust faster inside her and soon shot his semen into Mia's womb.
'Ah!... It's so warm inside me...' Mia thought as she felt his load filling her up. 'This feeling of being filled with hot cum while being under the cold water... I've never felt this before... It's so intense! Oh, Oliver, you're the best...'
As they both came down from their high, Oliver pulled out of his mother's pussy and moved away from her.
Jasmin followed his movement with her eyes, still fondling Mia's breast and tweaking the hard nipple. 'Now it's my turn to be pleased by Oliver.'
Without wasting time, Jasmin swam up to Oliver and wrapped her arms around his shoulders. 'Come on, Oliver, fuck me right now! Fuck me as hard as you just fucked your mother.'
Although Oliver couldn't hear her, he seemed to understand her gesture well enough since he immediately embraced her back.
Then, he grabbed ahold of Jasmin's ass cheeks and positioned his still erect cock against her pussy.
In response, Jasmin wrapped her legs around Oliver's waist, allowing him easier access to her wet hole.
The moment his penis penetrated her vagina, Jasmin threw her head back and closed her eyes as a pleasurable wave washed over her entire body. 'Mmmm! Yes... Oliver's cock is once again inside me! Aahhh...'
Oliver felt like his cock had gone to heaven when it entered Jasmin's pussy, surrounded by the warm and soft inner walls.
'God... I love this! I'm so glad I can do this every day whenever I want to...!'
Oliver's grip on Jasmin's ass tightened while his pelvis moved forward in rhythm with Jasmin's rocking motion, allowing his dick to slide even deeper inside her.
While they were busy doing that, Mia recovered from her intense orgasm, floating around with her eyes watching everything happening around her.
The scene playing out before her was just too erotic and captivating for her to take her eyes off.
Jasmin and Oliver were going wild with each other, and she loved every second of it.
Witnessing Oliver doing naughty things with other women always turned Mia on so much.
'My baby boy is such a horny beast, and I love that about him,' Mia thought to herself with pride. 'He's gotten so good at this since our first time...'
On the other side, the mother-son duo, along with the father-daughter duo, had their mind-blowing sexual intercourse while enjoying the cool ocean water.
A minute later, Henry blew his load into his daughter's vagina, causing her to shudder violently from the extreme pleasure that coursed through her body.
She grabbed ahold of his shoulders as she came down from her orgasm high. Her heart pounded away within her chest as she tried to regain her breath.
Roma looked into his eyes with a half-lidded gaze, wondering whether they should call it quits after such amazing sex underwater.
As for Jane and Adam, the two had reached their peak while holding each other. The orgasmic spasms overwhelmed their bodies.
Nevertheless, their embrace continued as they let themselves drift around aimlessly on the gentle sea current.
Eventually, everyone returned to the surface with a big smile on their faces.
Oliver, Mia, Henry, Roma, Jane, Adam, and Jasmin all looked at each other.
Seeing each other's expressions made them burst out laughing.
Oliver wrapped his arm around Mia's waist, holding her close to him while enjoying the breathtaking view around him. "How about we go back to the beach house? I think everyone wants to continue what we just did there."
Henry nodded his head as a big smile spread across his lips. "Agreed! I'll have to show my dear daughter, Roma, how much her Daddy loves her..."
He then grinned while looking at Roma, who was standing beside him. "...inside and out."
Those words caused Roma to shudder as she looked away with reddened cheeks, feeling embarrassed by his statement. "Whatever you say, Daddy..."
