Dean woke up. He wiped away the dribble from his chin. He looked to the side of his bed. Cas sat there reading one of his old demonology books.
"Alpha..." he turned to face Cas and scented the angel. Castiel took in the omegas scent. He licked Deans scent gland, taking in more of him.
"You taste different from your last heat," Cas noted. Dean knew that was because he was pregnant.
"Alpha," Dean didn't say anything else. He still had to pretend to be in the beginning of his heat. Cas smiled.
"Alphas here," Cas grabbed Deans chin and pushed their lips together. Dean continued kissing him as he moved to sit on the angels lap. He straddled Cas. As the angel kissed and nibbled at Deans collarbone, Dean slid his hand down to their dicks. He pushed them together and started to rub them against each other. His hips grinded, begging for more fiction. Castiel heard Dean whine. He lowered his own hand and held Deans hand down, putting more pressure on their dicks as they ran up and down the length of the shaft. Dean leaned into Cas and started to moan in Cas's ear.
"Cas," he whimpered, "knot me," his body ached for Castiel. Cas nodded and slowly leaned Dean on his back. Cas scooted back and looked at Dean.
He laid on his back, naked, legs wide open, presenting his leaking slit to Cas. The angel put two fingers in Dean. He curled them and twisted them. He searched for his g-spot again. He quickly found it. He wasn't up to knot him just yet but if he could make him cum and fall asleep, he would have a few more hours to get his strength back.
He pushed Dean so hard that he was becoming overstimulated. Tears rolled from his eyes and his body jerked in jarring positions. His fingers weren't going to cut it. Cas stuck his cock back into Dean. He picked up Dean in his arms. He turned the omega around, leaning his back against his body and pushed his length into his slit. His knot started to slowly inflate. It wasn't as big as last nights but it was just enough to catch on to Dean. The knot was in the perfect place. It rubbed right against his spot. Dean started to call out for Cas.
"Cas- Cas- harder Cas- don't- don't-" before he could finish, he finished. His body shook and trembled. He enjoyed the extra shocks of ecstasy when Cas pumped his dick in. Then Cas came into him again. He felt the eruption of seed sticking to his walls. He couldn't help it. He started to purr. Cas put his head on Deans shoulder, his hands wrapped around his midsection, feeling the purring deep in him.
While Cas's knot deflated he let Dean lay on him, subconsciously rubbing Deans belly without even realizing what he was doing. Dean asked for Cas to bond with him over and over, but Cas still refused.
