When it came to Asriel, she was reminded of all the happy times they spent together as mother and son, and she knew just what her son liked to do with her. He was a big fan of swimming and hoped to peruse a career in freediving someday, and seeing as she swam a lot back in her college years was more than happy to give him the training she could provide. Their swims were frequent and became very informal procedures as they kicked about the surface and dove under the rippling surface together, becoming an inseparable pair when they were underwater, and with each swim, they were becoming more comfortable to just ditch the swimwear and skinny dip together.
As each swim session passed, Toriel began to admire her young son's growing body, his baby fat toning into a nice, slender form that was easy on the eyes. He was growing into a much different monster than his father, he certainly wouldn't get his bulk and muscle but would turn into a slim, fine young adult. She always got a glance at his voluptuous curves and toned, rounded behind whenever he swam ahead, his member swaying back and forth as he pumped his legs.
Toriel hadn't noticed it before, but it seemed in his swims, he always seemed to grow quite flustered. He always seemed to blush whenever he looked at her naked form, large breasts and full nipples bobbing in the water, his penis growing quite stiff at times, especially whenever she touched his fur. Things really started to heat up when she found him diving underwater and not surface for some time, forcing her to dive down to see if anything had happened to her son, only to find him masturbating behind a rock formation, bubbling away as strings of cum flowed from his shaft, leaving her surprised and strangely lustful as he kicked back to the surface with what little air he had left.
Knowing he had a fetish for swimming underwater, she decided to help him with his needs. She thought he didn't need to pleasure himself alone with her around him. She knew that if she were to be of any help to her son, she would give herself to him to satisfy his urges. At first, she tried a more hands-on approach to his swimming, encouraging him to swim long and deep, or to swim close for warmth. She even had him hug her back as she swam like a dolphin, taking him deep as she felt his cock rude against her back, making him bubble with a satisfied gasp. Knowing what had to be done, she took her son to the lake and told him to get undressed.
As the two stripped down, Toriel jumped into the water and urged her son to do the same, “Come, Asriel. The water is simply splendid.”
She ducked under the waters and waited for him, pinching her nipple in a free paw and fingering herself with the other, letting out a bubbly sigh as her mind flooded with illicit thoughts of her and her son making love underwater. She pulled away when she heard a splash behind her, cocking her head to see Asriel floating behind her. With a lick of her lips, she toyed with her body, fondling her breast and beckoning her son to join her, his erection bobbing in the water, “Foblblow mebl honbley…”
She kicked off slowly as Asriel followed behind, swimming into the deeper reaches of the lake as the surface seemed to ascend out of their sight. Her son wasn't sure why she was diving so deep, but with a reassuring smile from her, he soon picked up the pace. Soon, they reached the lakebed as she turned to him. The young prince stopped as Toriel placed her paws on his shoulders, planting a kiss on his lips. This kiss, however, wasn't a friendly peck like she had given many times before, but a deep, loving smooch like he had never experienced. He was taken aback by her sudden affection, but grew to it quickly as he began touching her body, groping her breasts and stroking her fur. She turned her body around and bared her pussy at him, twitching from the needy lust she was getting from this situation.
“Mogblblmmy wanbls youbl, Abriegbl~...” She cooed affectionately.
Her son was hesitant to touch her at first, but with his twitching member, she knew he wanted this just as much as she did. He groped the flesh of her behind, watching the softness of her butt mold in his paws like dough. With a gentle push, she slid his cock into her folds as she let out a small, bubbly squeak, “Eepgbl!”
Sliding the shaft in slowly, he began rutting her in a slow, almost rhythmic speed. She helped along as she bobbed on his dick, her breasts and chubby belly dancing in the cool water, her nipples standing firm. The couple were letting out low, bubbly moans as their fun was just getting started, their bodies filled with lust and need for each other.
Asriel gripped at her mother’s thighs and gauded her body to sit upon his member, the water negating any issues regarding her weight. Toriel felt her son pick up the pace as she helped him by rocking her hips to his slow, methodical thrusts. She slung an arm around him and smiled as her body was filled by her own son, “Asriel, my darling son, ravishing me with such talent underwater!”
Asriel could feel the heat from her mom’s inner walls hug tightly around his dick, his body shivering with excitement as bubbles frothed from his lungs, “Mmmpphhbglbl!”
The two were very much in the heat of the situation, Toriel letting her son take over as her chest convulsed after letting out long strings of air. Asriel wasn't much better, his cheeks glowing red as his cheeks puffed up. The couple were hungry for air and were tempted to swim up and get a breath, but their need to orgasm was top priority at this point and they weren't going to lose this golden opportunity to show their love for one another.
Toriel could feel something stirring inside her, her pussy swirling with her love juices, she was getting very close to an orgasm as Asriel began pumping her pussy even faster. “Ah-ahhnbl! Nngblahn~...”
He too was in dire need of a breath but was now teetering on the brink of a massive orgssm, his member almost engorged with his seed. He puffed his cheeks up more as his lungs were at bursting point, “Mmmnngpphgblobl!~”
“Abriegblbl!!”
“Moogblmbl!”
And as if a bomb had gone off, the two came heavily into the waters, air bubbles frothing from their mouths in large clouds, cum leaking from Toriel’s quaking pussy, even with some milk messily leaking from her tits as they cried into the depths, “NNHHAAAAHHNNGBLAAABLBLGBL~~!”
Their comedown was short, but it drained the couple dry. As they shared a kiss and broke apart, Toriel and Asriel’s cheeks turned a deep shade of blue from all the discarded air, cum still leaking from the queen’s folds as Asriel let out a small succession of cumshots. The young prince could hardly focus as he tried to swim back to the surface, his body exhausted and heavy and could only flail his arms weakly.
Luckily, Toriel had some energy left and carried her son in her arms, letting her swim for the both of them as they swam up from the depths, their love juices still leaking. The couple would certainly try this somewhere shallower, but they knew their lust for deep, underwater sex was going to be needed much later. The queen looked at her weary son, looking at her as he fought to stay conscious, convulsions wracking his body, as she planted another soft kiss and kicked for the both of them, hoping to soon reach the surface.
“Asriel, you were simply wonderful today. I hope you won't mind if I go on bottom later~…”
