“I don’t know how to talk about such things.”
Contractions. Castien used contractions only when he was angry—or uneasy or very bothered by something.
Eridan cocked his head to the side and regarded him for a moment. Maybe it wasn’t that Castien didn’t have deep feelings; maybe the problem was his inability to communicate about them after years of carefully eradicating any strong emotions. Maybe he just needed to loosen up first. To lose that ironclad control.
“All right,” he said, his voice softer. “Let’s have an honest conversation. I’ll start, to make things easier for you. Do you know I was eighteen when I started touching myself thinking about you?”
Castien’s nostrils flared. He stared at Eridan with blown pupils.
Eridan suppressed a smile. “I couldn’t even stand you back then, but something about your awfulness, and your cold, high-handed attitude made me so frustrated and horny I touched myself all the time, stuffing my fingers inside me and imagining it was your cock.”
A faint flush appeared on Castien’s cheekbones. He swallowed and opened his mouth but didn’t say anything.
Eridan leaned in and pressed his nose against Castien’s cheek. Breathed in. Felt Castien stiffen, his body practically vibrating with tension.
“It was really fucked up,” he said. “I didn’t even like you back then, but you were the only thing I thought about when I masturbated.” He whispered against Castien’s ear, “You made me so wet, Master.”
Castien made a low sound, his hands grabbing Eridan’s ass and yanking it against his clothed crotch. Eridan gasped at the feel of the hard bulge of Castien’s arousal pressed insistently between his legs. His body felt weird. It wanted, his hole clenching, dry but oversensitive. It felt off. His entire body felt off. It was immensely frustrating and disorienting. He felt so aroused, but only his cock was reacting as expected, becoming hard and slick with lubricant, but his hole remained dry.
“Oh,” he whispered breathlessly. “I feel strange.”
“I did warn you about that,” Castien said, his voice tight as he peppered Eridan’s neck with hungry kisses and hickeys. “Blocking the throwback part of your brain would affect your physiology, too.”
Eridan shook his head, fighting the disoriented feeling. “Fix it. Fix me. Take the block off. Wanna have you inside me.”
Castien’s muscles went rigid. He was breathing unsteadily, his hands still holding Eridan against the hard bulge of his cock.
“No,” he said in a clipped voice. “I’m in no state to do it now. I need a clear head. I might hurt you.”
“I trust you, Master.”
He made a startled noise as his back hit the couch.
Castien climbed on top of him, bracketing his head with his forearms, his gaze dark and glassy. “You’re terrible for my control,” he muttered. And then he leaned down and kissed him, if that could even be called a kiss. It felt like Castien was trying to consume him, to devour him, to get inside of him through his mouth, the kiss so hungry and intense that it quickly overwhelmed Eridan. He could only take it, sucking happily on his Master’s tongue and moaning in utter bliss.
He slipped a hand between them and jerked Castien’s fly open. When his hand closed around Castien’s thick, leaking cock, he groaned, his hole tingling. There was still no slick, but at this point Eridan kind of didn’t care. He wanted him inside. Castien’s cock was coated with lubrication, which betrayed how aroused he was. It would be enough. It would be more than enough.
“Fuck me,” he whispered against Castien’s mouth. “Want you inside of me.”
Castien shuddered on top of him, his erection becoming even harder in Eridan’s hand.
What happened next surprised him. Eridan had expected that Castien would simply take his pants off and stick it in, but Castien stripped him completely and then just stared at his naked body with glazed eyes.
It made Eridan feel beautiful and wanted, his skin tingling and his cock aching. He spread his legs and said, “Master.”
Apparently, that was enough to make Castien move. He trailed kisses down Eridan’s neck, sucking bruises into his skin and then licking his nipples. He sucked on them for a while, making Eridan whimper breathlessly. His nipples had always been so very sensitive, and when he’d jerked off, he’d always imagined his Master sucking on them. The reality was better than any fantasy. Each gentle suckle seemed directly connected to his cock and his hole. Soon, Eridan was writhing under Castien, clawing his back and holding Castien’s mouth against his nipples.
Finally, his Master moved lower, his lips tracing his abdominal muscles, and then lower. Eridan cried out as Castien took his hard cock into his mouth and sucked.
“Be quiet or someone might hear us,” Castien told him telepathically, bobbing his head up and down, his mouth relentless and wet.
Eridan couldn’t be quiet. He had to bite his own hand to muffle the sounds he was making, his other hand burying in his Master’s hair and pushing him down on his cock. It felt so good.
