Grian laid on his bed, shifting uncomfortably. How did he get himself into this situation?
He was extremely horny, and sick.
He heard someone moving downstairs, and sat up to figure out who it was.
Mumbo walked up the stairs to Grian's room, and stopped in confusion.
Grian looked like shit.
His hair stuck to his forehead, his red sweater was thrown onto the ground and his black tank top on instead. He seemed both half asleep and half dead. His wings were folded behind his back, flinching every few seconds.
Griam tried standing, but fell to his knees, causing Mumbo to rush to the shorter.
Sitting Grian back down on his bed, he noticed the feathers around the room.
"Grian?" Mumbo asked helping the shorter stand.
Grian flushed red at the mention of his own name, but looked into Mumbo's eyes.
The two sat on Grian's bed, Grian practically laying on top of Mumbo. Mumbo sat up against the bed frame, with Grian on his lap.
"Grian... You okay?" Mumbo asked, holding Grian tightly.
Grian once again flushed red, his body getting hotter. His wings fluttered lightly. Mumbo noticed, and rubbed Grian's back in a circular motion. Causing Grian to hum. Mumbo raised an eyebrow, but continued causing Grian to melt under his touch.
"Grian... Are you going through your first heat?" Mumbo asked, slightly laughing.
Grian raised an eyebrow, but then realized his head was buried into Mumbo's chest.
"...What's... heat...?" Grian managed to speak.
Mumbo chuckled but held Grian closer to him.
"Most hybrids go through it once or twice a year, but it's basically that your sick and the only way to help you is to have sex. However, most of the hybrids can get pregnant easily in their heat." Mumbo explained. "Basically everything is more sensitive for them."
Grian tried to nod, but stopped midway through to catch his breath. Mumbo blushed a tiny bit, but nice his right hand and started rubbing the wing.
Grian moaned and melted under Mumbo's touch. He continued, bringing Grian closer and closer to cumming. Grian continued moaning, and was amazed at the feeling.
Mumbo's hand reached down to Grian's crotch, and started rubbing against the hard dick.
It didn't take long for Grian to cum, and Mumbo noticed that Grian was still hard however.
"Do you want more?" Mumbo asked.
Grian panted but nodded.
Mumbo slid their pants and underwear off, positioning Grian above Mumbo's dick. Mumbo kissed Grian, before allowing Grian to fall onto Mumbo's dick. His ass being filled by the dick and his legs shaking from pleasure.
Mumbo held onto Grian's hips, and helped him bounce on the dick. Mumbo thrusted upward everytime Grian came down on the dick, causing more pleasure for the sensitive blonde.
Grian came again all over their shirts, and Mumbo took that as a sign to reposition them.
Grian laid on his back against his bed, with his wings fluttering and flinching around him. Mumbo held onto Grian's hips tightly, as he began to fuck Grian.
Mumbo sped up, fucking Grian into the mattress below him, and Grian moaned as the pleasure just got better and better.
Mumbo felt himself getting closer, but because he didn't know if Grian could get pregnant with being in heat and Avians being rare, he pulled out.
He rubbed there dicks together, stroking them at the same pace without effort.
Both of them came all over their shirts again, and Grian laid there smiling like a goof.
Mumbo slid off the bed to grab something to clean them up with, while Grian came down from his euphoria.
He and Mumbo had sex, and Grian learned that Avians go though heat. And he learned that having sex during heat was amazing.
Whatever the hell Heat was anyway.
Mumbo returned and cleaned the up, and helped Grian change. Grian was pretty weak from being in heat, and just having sex.
Mumbo put his clothing on, dropping his tie and over coat onto one of Grian's desks.
They hugged as they laid down. Grian was still smiling, and Mumbo was starting to kiss Grian's forehead. Grian giggled as the mustache tickled his forehead, and Mumbo smiled.
