Shortly after Pascal's genital swap Cuda offered to help him learn a bit more about himself. He laid the dog down on a comfy table and helped him to relax by massaging up and down all over his body. Once properly loosened up he kindly asked the him to spread his legs, and plant his paws firmly on the table.
"You'll let me know if this feels uncomfortable, ok?"
Pascal nodded and his tail began to swish as his anticipation built up. Cuda's hands both traveled down to his nethers, the left one pressing down on his pubic bone and the right one cupping his chubby mound. The roo rubbed this spot gently yet firmly, eliciting a happy sigh from the dog. He then curled two fingers and slid them inside the soft warm opening. Pascal's mind raced, his arousal already building up as his friend prepped him.
"What I'm going to do may seem a bit jarring. Just give me two loud barks to let me know to stop."
"Sure thing!"
Pascal took a deep breath, and then felt as Cuda began to firmly jostle his nethers. He was right! I-it... it w-was a bit...
Pascal's mind quickly went from reality, a place where he could form thought, to a place where his brain was spaghettified. Cuda REALLY started to jostle him, and that other hand pressed just a bit more into his pubic bone. Each and every time those fingers jerked upwards Pascal could feel a multitude of pleasurable shocks ripple through his whole pelvis, only for Cuda to push his hand back down firmly against his mound... and up again! This was happening so quickly he could barely comprehend it, his hips started to wiggle and squirm on their own and his arms and shoulders kept tensing up and desperately moved about in some attempt to mitigate the sheer overload of sensations taking over this one small area of his body.
It was no use though. Cuda had obviously known this was going to happen since his arm kept his whole torso and chest pinned to the table. Suddenly Pascal realized the only thing he could do was let go and let his body react however it was going to... but he didn't dare bark twice. This may have been an overload but it was also quickly becoming the most pleasure filled moment of his entire life.
He let out a gasp and then a soft squeak, almost as if he was being tickled and he couldn't control his own sounds. His plump little rear kept trying to lift the big strong roo's weight but failed, instead he could only hopelessly squirm. Cuda just kept going though! And what felt like minutes had really only been mere seconds! Another whimper escaped, then a whine, and he tossed his head side to side as his toes curled up and splayed. His paws were scrambling against the table, his hands darting all over, his knees buckling in then spreading wide apart. The canine had totally lost all control over himself and merely ten to twelve seconds in he let out a deep moan from within his belly.
Cuda's ears perked as he watched him squirm and wiggle like crazy, but not hearing any barks... he kept going. In fact, he turned it up a notch. His hand became slightly more aggressive in its actions, making sure to really press up and dig his finger tips into the soft insides he currently commanded. He could feel Pascal's inner walls start to ripple and flex, making squeezes around his digits as things really started to ramp up.
Pascal's eyes fluttered shut and opened wide, repeating over and over as his whole body began to shake. His plump pussy had turned a deep shade of pink as his arousal had reached its max, and suddenly he felt something completely new start to happen. He'd already had an orgasm with his new genitals before, but only once. He felt himself tighten up hard, forcing him to gasp as he realized he was going to orgasm. But this time his walls didn't just tense.
With a sudden jolt Cuda pulled up harder than usual and in just a brief moment Pascal was completely sent over the edge. His sanity was gone in this moment, his thoughts vacant. His hips suddenly surged upwards without his consent or input and his toes curled hard, forcing the weight of Cuda's arm off. He grasped the edge of the table and dug his fingers into it so hard he felt the wood indent. The poor dog had never felt anything like this before. He let out the loudest most guttural moan of his life and then wailed happily before being completely silenced. His face turned screwy as his pussy walls squeezed so tight they pushed forward and bulged outwards. He felt the pressure on his bladder suddenly increase ten fold as the muscles in his pelvis all contracted at the exact same time, and with this he shot a thick continuous jet of clear liquid straight up into the air. He growled in intense pleasure as he came harder than he ever had previously, his hips thrusting upwards again to shoot another round of ejaculate clear across the room. He felt his insides ripple and squeeze together, relaxing only just a bit before pushing together and bulging outwards again.
Cuda's eyes went wide and he pulled back quickly, putting his hands in the air to let the dog roll through his orgasm. He watched as the canine twitched and shook from head to toe, the deep moans continuously emanating from deep within his tummy. He blushed a bit too, knowing he'd just given his friend one of the most powerful feelings he could go through. And judging by the lack of barks... he'd done his job well.
Pascal's hips bucked and wiggled without his control, his pussy rippling again and again. The muscles in his pelvis had all been triggered by his orgasm and every half second he would shoot another jet out. He humped the air as if he was grinding on it, his plump mound wet and swollen. He couldn't stop it if he tried, he was at the mercy of his overstimulated nerves as they pulsed and rippled uncontrollably. Every so often he'd let out another gasp, his face still contorted in pleasure and his cheeks flushed.
....
As the next couple of minutes passed Cuda stood by his side and pet him gently, rubbing his ears and tummy, watching the big goofy smile on Pascal's face as he wordlessly rode out his full body orgasm. At first he continued to squirm and wiggle, but eventually just laid still and breathed in and out slowly. The dog let out a sigh, finally, and placed his hand on top of Cuda's while it rubbed his tummy.
"P-p-please... c-c-can we go get McDonalds... and then do that again?"
