“Grizz… now. I want you..your… please..”

Panda reestablished his mouth and made breathy words; “Grizz… now. I want you..your… please..”

Grizz perked at the first word and nodded at each one. He began moving like a soldier on his first day; harsh purposeful movements and forced grunts that betrayed his nervous breathing. His solid pud reflexively pulsed; the bear’s body was more than ready, regardless of his mind’s complications.

He leaned in again and mumbled low “Are you sure, buddy?”

Panda could only glance up for an instant and he blushed still. Having the brown bear above him and thinking about what he wanted them to do now. Afraid, but not really. It was just Grizz. He thought of the stronger bear pressed up against his lower abdomen and raised legs, and then he looked at his own body. It was so soft, and pudgy and...cute, just as Grizz always tells him. It was so easy to think of why it was wrong but it was just as easy to feel how it was right to be here like this, with the bear that he knew better than anyone. It was right enough to go further.
“Yeah”

Grizzly relished to hear. A big cute perfect panda bear. What more could a friendly grizzly bear want? He loved the bear even more then and his excitement grew, but now he was responsible for Panda’s needs too.
“...ok!”
Panda had felt so exposed and chilly when he had cleaned himself but it was different now. His rear was in the same way but now the big brute was right up against it and it was different. Not just exposed but… connected. All he wanted was to be as accommodating as he could to the grizzly bear that beheld him.

By now Panda had adjusted to his underside feeling all wet. Grizz had probably used too much of the lube bottle while they were ‘warming up’. Maybe they took too long? Why would that matter? He was stalling. They both were. Grizz was shifting his glance from the Panda’s face to to the scene at his crotch and then back again.

Grizz nervously spoke again.
“You u-uhm...so ...you’re….ready?”
“Yea-y-yes.”
Panda was a little overwhelmed merely to lay there while watching Grizz, let alone be the one to start doing… everything. He thought fast.
“Oh! Here.”
Panda quickly flipped himself around on his bed and stuck his round bottom up in the air.
“I think this is the um, beginner way.”
Grizz wasn’t used to feeling awkward, at least not without quite knowing why, but he felt relieved now, somehow.
“Oh, yeah.”
Panda’s ample rump filled Grizzly’s view and he pitched his pud up with his pelvic muscle and felt his member throb in response to it.
Panda was similarly relieved, and allowed himself to get excited again, but his nervousness seemed to match it.
“D-do the digits one more time, and then… go, ok?”
“Ok little bro.”

Grizz groped at the panda bear’s aboundant backside and around the still wet opening. He let a paw digit slip in and it went in easily, as did two, and three. They had definitely taken their time. He reckoned that Panda opened up easier than he had thought before they started and that gave him a lustful grin as he looked down at his pulsing shaft in his paw, now lined up with Panda’s eager entrance. The time had come.

Grizz pushed at Panda’s tailhole and, to his surprise, the bulbous swollen head slipped in with hardly any resistance.
He dared  push again and stumbled forward unexpectedly, and just like that, he was as far inside Panda as he could go.
“A-aah!”,Panda yelped.
Grizz scrambled to regain his balance and his penis slipped back out in the process.
“Sorry! You ok Pan?”
“Um...yes”
Panda never had anything go so far in. It hurt a little, in a strange way he hadn’t felt before, and in the same strange way it felt good, if only too sudden. And he thought about it being a part of his big bro and that was really nice. He craned his head back but didn’t quite make eye contact.
“Keep going”
Grizz wouldn’t have heard the quiet command if he had not been frozen listening so closely. He wasn’t much louder.
“Ok.”
He slowly guided himself back into the warm, wet folds as he shuddered at the intense sensation on his shaft and head. It really wasn’t tight at all like he thought it might be. But it wasn’t too lose for him to feel everything, it was… just right. Something about that made Grizz even more excited. His little Pan Pan let him in so easy. He pushed in again, and then out again, but faster.

Panda made a weak yelp, now quiet and less alarming. Grizz thought to ask if Panda was ok again but had a second thought. He’d say something if it hurt, right? He takes it so easy. It must feel good for him. Grizz pressed in a third time, and then a fourth and a fifth. His thrusting became rhythmic and he stopped counting.

Panda’s noises similarly blended into ongoing breathy cooes that pitched up each time Grizz bottomed out inside him. Runny precum oozed from his own penis, which remained semi soft, hidden within folds of foreskin. The feeling was as confusing as it was pleasurable. There was a dull soreness that underlied waves of gleeful sensation. He wouldn’t admit that he sort of liked the hurt too, because it made the waves feel that much better, and they were coming faster. But Panda wanted them faster still.

Grizzly’s ears were fixed onto Panda’s vocalizations, and they served as a metronome for his thrusting and assured him that he was giving the panda bear what he needed. With confidence, his actions became more automatic. His back hunched so that his arms could wrap around and reach the sides of Panda’s pudgy belly and his snout could plant onto Panda’s lower back and lapp up the sweet scent of his adorable little brother. Grizz felt an aggression building inside him that served to keep up his thrusting pace despite normal fatigue. But he had kept it in check until he heard Panda breathe in and speak.
“Grizz...faster” Panda practically moaned. “H-aah-arder...please”

Grizz surprised himself when he responded with a grumbling growl instead of the “OK” that he intended. A sudden wave of energy unleashed within him and his thrusts quickened rapidly. He began to use his weight to bear down on the upturned rear of his mate to probe his throbbing pud ever so slightly deeper and brush harder against Panda’s sensitive, virginal depths.

Panda worried to feel the ache increase as simultaneously he drowned in the rushing waves of ecstacy. His pud now fully hard, peaked just past his foreskin and streamed out clear fluid, which seeped under the crease of his oversized gut and down to his dark furry orbs, all of which smooshed together into a wet furry mess so that his massive rear and  loose slick hole could remain arched up in their expected position for continued pounding. The diametric feelings of pleasure and pain overwhelmed him but the thrusts just came faster and harder, exactly what the big soft submissive bear had begged for not long ago.

Grizzly’s thoughts melted away and his instincts took control. He grunted and growled and shook and thrusted and sniffed and growled and thrusted. Panda’s sensations were crowded by growning fear and he was further panicked to feel a quivering uncertainty from the very chubby gut that got him into this state, but he could sense a changed air about Grizz and feared that stopping may not be an option now. Panicked, but yet his mind and his battered rear could still agree on one thing: It may hurt, but it feels soo, soo good. And he loved the pain anyway because Grizz gave it to him. He loved his big bro.

So the tubby Panda bear kept his snout in the pillow and his stubby tail raised high. Grizz would do his deed until he was done and there would be no protest. That valuptuous backside jiggled as it was pounded and it sent a stream of pain and exponential pleasure to Panda and all Panda did was receive it. Tears leaked from hard shut eyes and dripped over a goofy grin. He belonged to Grizz. And it hurt. And it was so good. And he was scared of Grizz. But Grizz made it so good.

The brown bear instinctually hilted and stayed at the deepest point he could with all his weight pressed again’st Panda’s well-eased opening. Grizz had orgasmed before but this was different. His whole lower abdomen vibrated automatically. The vibrations carried to the tip of his pud and his bellend flared. Panda could feel every vibrating inch from deep in to the rim of his sensitive opening and he squealed to respond to the stimulation. Pearly white gobs of grizzly bear seed gushed and spurted even deeper inside Panda’s welcoming pudgy form. Panda had some sort of instinct of his own take over as his lower body pushed itself up towards his brother’s inseminating probe. The climaxing sensations in his spasming rear demanded his attention such that neither bear noticed Panda’s stubby shaft rapidly squirt a stream of milky runny ejaculate, which dripped down his thighs onto the bedding below.

Grizz slumped sideward off of panda’s behind as he was lifted out of his instinctual haze. Panda felt so light and exposed. The younger bear was glowing with warmth but winced when unknowing, he lowered his hip onto his own puddle of ejaculate. He shifted away from the spot and turned sides but the a draft grazed the area and made him shiver. He felt the ache still inside, but in the same spot now there was Grizzly’s warm deposited seed. He wasn’t sure if the ache was fading or if he was just getting used to it but it wasn’t the center of his attention now. Panda’s mind pushed in to analyze what they had just done. Was this ok? What does this make you? What are you now? His mind raced. He didn’t want Grizz to see but he it couldn’t hide anything now.
He caught Grizzly’s eye and saw concern brewing.
“Pan pan..”

Panda needed to say something to assuade his big bro but he didn’t want to make anything up. Cold air prickled his wet rear again. He noticed the wetness near his swollen tailhole, and the ache. He frowned and Grizzly’s eyes widened in fear. Panda thought about the wetness inside… about what was in him now, the seed that his big Grizzly brother put inside him, he felt the looseness of his hole and the big pud that did it too him.

He quickly came up and kissed Grizzly’s snout and ducked a paw down to find the brown bear’s half engorged shaft. He looked up to Grizzly’s eyes and gently pulled at the ample foreskin as he whispered something true.
“It felt really...really good”
Still gentle but sturdy, he squeezed the shaft from the base to the bellend and collected the remaining seed in his palm, and he kissed Grizzly’s snout again.
“Thanks big bro”
Grizz softened his look and weakly smiled in relief.

Panda’s eyes welled but didn’t break. He didn’t have the energy to think about why. Grizz rolled to one side and let his arms go limp to let the other bear reposition however he wanted. Panda folded his blanket around his chily rear and ducked down to Grizzly’s chest. He mumbled and poked his nose out under Grizzly’s arm to breathe. Thoughts came but they didn’t linger. Panda wasn’t sure again, about what they had done or what they should do. And he knew that Grizz didn’t know either. But Grizz was here so he could fall asleep, and that was good for now. His eyes became heavy, but then he remembered the pearly cum still in his clasped paw. He quietly brought it up to his mouth and without a second thought, ran his tongue through his big brother’s  remaining seed and played with it in his mouth for a moment before gulping it down, and closed his eyes with a calm satisfaction.

Grizz shifted his paws and arms slightly to feel the soft round contours of his brother’s form. Panda was ok. And he’s with me. This is good. Good for now.
