I used NovelAI's unlimited gen membership for $25 a month. Note that "unlimited" is kind of a lie, it's only unlimited if you're under a certain resolution and only if you're not using any of the advanced features. Upscaling and other features cost the on-site currency, which the membership gets you 10000 a month. That should be more than enough for a month, but you can burn through it quickly since NAI gens so quickly.

♫ I love you~ ♡ You love me~ ♡

The bedroom was filled with cheerful singing and the wet, rhythmic sounds of passionate lovemaking. Barney’s big, friendly purple body stood over the bed, his enormous pink cock — thick as Baby Bop’s wrist and longer than her forearm — sliding deep into her tight, dripping green pussy with every loving thrust. His massive, heavy balls slapped rhythmically against her pink-spotted rear, the lewd *plap-plap-plap* mixing perfectly with their happy song.

“We’re a happy family~ ♫” Baby Bop sang breathlessly, her voice cracking into a cute moan as she lay on her back with her legs spread wide. Her fluffy green head tuft bounced wildly with every powerful thrust from her big purple lover. Her heavy breasts with perky pink nipples jiggled hypnotically as Barney fucked her senseless.

“Oh Baby Bop, you feel so wonderful today!” Barney sang cheerfully, his big friendly smile never fading even as he drove his gigantic cock balls-deep into her. “You’re so tight and warm and perfect~ ♡ Just like a big hug, except… much wetter!”

Baby Bop giggled through a moan, her eyes sparkling with love as she reached up to hold his green belly. “Barney~♡ Your big dinosaur dick is so huge! How can someone so sweet and friendly have such a massive, throbbing cock? It’s stretching me so good~!”

Barney chuckled warmly, his voice full of pure affection as he picked up the pace, pounding her deeper. “Well golly, I guess even friendly dinosaurs have big surprises! ♫ I love making you feel good, Baby Bop. Every thrust is filled with love and friendship!”

He angled his hips and slammed in particularly deep, his heavy balls smacking wetly against her. Baby Bop’s eyes crossed in pleasure as she let out a loud, happy squeal. “Ahhh~♡ Yes Barney! Right there! Your giant cock is hitting all my special spots! You’re such a good lover~!”

The purple T-Rex grinned proudly, sweat glistening on his smooth hide as he continued singing between groans of pleasure. “You love me~ ♫ We’re a happy faaamily~” He reached down and gently rubbed her clit with his big finger while continuing those long, powerful strokes. Baby Bop’s toes curled, her pink claws flexing as another orgasm rushed through her.

“I’m cumming again, Barney~! Your big friendly cock is too good! ♡♡♡” she cried out happily, her pussy gushing around his thick shaft.

Barney’s eyes sparkled with joy. “That’s my special friend! I love when you cum on my big dinosaur dick!” He leaned down, still thrusting steadily, and planted a big, loving kiss on her snout. “You’re so beautiful when you’re full of me~”

His massive balls tightened as he approached his own climax. “Oh dear… I think I’m gonna make a big love mess inside you, Baby Bop!”

“Yes, please~♡ Fill me up with your warm dinosaur cum!” she sang back, wrapping her legs around his waist.

With a big, happy roar that somehow still sounded wholesome, Barney buried himself to the hilt. His enormous cock pulsed powerfully as he unleashed rope after thick rope of hot, creamy cum deep inside her. Baby Bop’s belly visibly swelled from the sheer volume, excess seed squirting out around his shaft with every throb.

They stayed locked together, panting and singing softly as hearts and musical notes floated around them.

“I love you~ ♡ You love me~ ♡ We’re a happy family~” they sang together, voices full of pure love and afterglow.

Barney gently stroked Baby Bop’s fluffy green hair, his still-hard cock twitching inside her cum-filled pussy. “Gosh, I sure do love singing *and* making love with you, Baby Bop. You’re the best friend a dinosaur could ever ask for~ ♡”

Baby Bop giggled, squeezing her inner walls around his massive length. “And you have the biggest, friendliest cock in the whole wide world. Let’s sing another round, okay?”

Barney grinned wide. “Super dee duper idea!”

And so the happy purple dinosaur and his beloved green triceratops continued their very special, very sticky version of the Barney song late into the night, proving that even the friendliest dinosaurs can absolutely wreck a pussy while staying wholesome at heart.

♫ We’re a happy family~ ♡
