After a few deep breaths, the queen and prince dove deep into the river as they kicked into the tunnel. The change in pressure was noticeable almost immediately, hugging their nude forms as they swam deeper into the hole. Toriel looked at her son, her eyes trailing up his nubile, naked form as they shared a smile through pursed lips. Her breasts bobbed with each pump of her thick, powerful legs as the young prince swum beside her, his member flopping slowly between his legs. “That is it, my child. You are doing such a wonderful job.” She thought, mentally praising her son.
They spent some time swimming through the tunnels, sticking close by as they turned corners and swum up and down slopes, picking directions as they made their way to intersections. The two were amazed by the network of tunnels, all glowing a shade of blue from the Waterfall’s heated waters and crystals scattered amongst the walls. The two enjoyed their time exploring the depths, rolling on their backs and dolphin kicking, or doing playful flips and spins as they shared bubbly giggles as they brushed against the underwater foilage. Their naked forms did not bug them or hinder their progress, Asriel watching her mother's nipples grow hard as the water pressure gripped tighter, the water growing colder as his member started to grow erect.
Asriel felt his chest slightly convulse over time, but a few short exhales soon rectified that issue, Toriel doing the same as her tits swayed slightly with each chest convulsion. The couple were confident on their breath holding capabilities but they knew they could not stay underwater forever, as Asriel grew increasingly concerned over how far they were swimming away from where they came from.
They did not know how long they were underwater, but now it was becoming too long. As they continued to swim along a tunnel, Asriel felt his lungs twitch heavily, making him gurgle away some air, “Nngbhgbll!...”
Toriel felt a prang in her own chest and stopped their swimming, signalling to her child if they wanted to go back. Asriel nodded and they turned back through where they came. The queen had the tunnels they travelled in mapped out in her head and knew exactly how to escape. All she had to do was to take the next left after the corner ahead.
Or was it right?
She was sure it was left, but she was also sure she went straight ahead after taking that left turn, or did she take that other left up ahead. She peered at the corner, her memory failing her if she did take the turn. She pressed on anyway, a worried Asriel following beside her as he let out another breath of air to relieve his tired lungs. Toriel stopped at an intersection, swimming to her right and kicking on ahead past the coiling tunnel, but she was back where they decided to head to the exit. She swam back and took the nearest right out of the intersection and decided to swim ahead and see where it would take her. She pressed on, her lungs growing more and more tired as they swam through the dimly lit tunnels, “Hmmgbl… Nngblbl!”
Asriel kicked close to her mom, taking her paw with his own as they continued trying to find the right exit, his member still half-erect from earlier. The queen and prince then found themselves at a totally unknown intersection as each path lead into further darkness and confusion, coming to a halt. They were completely lost, trapped in an underwater cavern with a dwindling air supply between the both of them.
Toriel felt her lungs sting inside her as she pressed a hand against the ceiling, her cheeks puffing up as air poured from her pursed lips, pumping her thick, powerful legs to keep her afloat, “Gblk! Gblblmghkbl!”
Asriel too felt his lungs prang inside him, his legs kicking. The caprine felt himself start exhaling uncontrollably, puffing his cheeks up as he watched his mother slowly drown with shrunken, panic filled eyes, his hand clutching his throat, “I--I can't hold on, I gotta breathe!” His mind fretted in his head, a hand placed against his chest feeling his soul racing a mile a minute, watching his escaped air pool on the ceiling above them.
The two remained struggling for some time, unsure if they had the strength to carry on and even if they did, they would not have enough air between them knowing they dove for a long time before heading back. The queen and young prince would eventually press on, but they knew that their fate at this point was almost inevitable and their continued swimming would only delay what was coming as their lungs seared painfully inside them, begging for a breath of fresh air, knowing full well that their escape was somewhere in these deep and confusing underwater tunnels, they just didn't know where.
Nobody was happy with this.
