Aquarium Love (KiriBaku) Mermaid Au pt 6

"'Mon, split me open on that beautiful cock of yours." Bakugo whispered nibbling the shell of Kirishima's ear, "I want every egg you've got in there so don't you dare hold back." he added with a soft growl

Any lingering concern Kirishima may have had about whether or not Bakugo really wanted him disappeared with the confidence in his tone. He kissed and bit his way down Bakugo's body, he licked a stripe up a half hard cock before hooking Bakugo's legs over his shoulders and plunging straight into puckered flesh with vigor.

Still sensitive from cumming, Bakugo trembled as Kirishima's hot wet tongue slowly worked him open. He loved the way the clicking vibrated against his skin making it tingle. It felt so good his cock quickly filled out again. Despite the oversensitivity, he was starting to get restless, he wanted Kirishima deep inside of him. He gripped Kirishima's hair, roughly yanking him up into a heated kiss full of teeth and need.

Kirishima yelped when Bakugo flipped him over, roughly pinning him to the bed. His mouth watered as he watched 'helplessly' as Bakugo one handedly coated his cock with lube and lined himself up. Sure he could easily yank his wrists away from Bakugo's grasp but the view was too good and feeling like he was at Bakugo's mercy was such a head rush.

Slowly, Bakugo lowered himself onto Kirishima's cock. The stretch burned in the best way as the tip slipped in. He resisted the urge to just drop himself on it, properly impaling himself. Instead, he leaned forward and pressed sloppy open mouth kisses down Kirishima's neck, leaving a trail of spit and scales. He was dumbfounded by the slight slits that started to form before he suddenly remembered their earlier conversation about gills. "Shit." He reached over for his discarded shirt and dried off Kirishima's neck. "Sorry forgot." he apologized softly as he resumed kissing, this time opting to kiss from Kirishima's jaw up to his temple.

"'S okay." Kirishima whispered dreamily, he could hardly focus on anything other than where Bakugo's skin met his or how tight and hot Bakugo felt around the tip of his cock. He rocked his hips gently just barely tugging against the rim.

"Fuck, sorry I can't take it anymore." Bakugo whined softly as he gripped Kirishima's wrists tighter

"Wh/" Kirishima was cut off by Bakugo sucking on his lower lip and before he even had a chance to think Bakugo dropped himself, shoving his cock in so fast he almost came. They both groaned into the kiss as it slowly devolved into biting and tugging like they were trying to devour each other.

Pulling himself back up slowly, Bakugo relished each ridge tugging against his rim. Once he reached the tip, he slammed himself down again, tossing his head back, moaning loudly. He did that twice more before setting a fast harsh pace that he'd probably regret tomorrow but right now all he cared about was how amazing Kirishima felt, how every thrust grazed his prostate just the right way and was accompanied by a delicious tug. He only vaguely registered that Kirishima was trying to tell him something before he was flipped back over and being pounded into the mattress.

"*click* You ready? *CLICK* Ready for my eggs Katsuki? *click*" Kirishima groaned against Bakugo's neck as his clicking got louder and lost its rhythm.

"Fuck yes~" Bakugo moaned rubbing his face against Kirishima's neck "Make me cum with them~"

With a loud groan Kirishima's cock started to pulse and stretch, the squeeze where Bakugo's rim was sitting was painful, instinctually he pushed forward hard, forcing it in. He kept pushing till his knot pushed at the tight ring of muscle. Would it even fit?

When Kirishima paused, Bakugo looked down to see what was wrong and almost laughed at the way Kirishima was drooling, eyes glazed over, clicking more rapidly, clearly trying to resist just shoving his knot in. He wrapped his legs around Kirishima's hips and yanked him closer with as much force as he could muster without clamping down on the cock inside him. He groaned at the pain when the knot popped in, damn near ripping him in the process. He was definitely going to feel that in the morning. But the fucked out look on Kirishima's face was so worth it. He'd never seen anything nearly as beautiful and he doubted he ever would.
