"What do you mean you 'took care of it'?" Sumas pushed Suraci away instantly afraid he had done something permanent to their body while they were unconscious.
"I mean I was able to create a polymer with some of the local flora and fauna that I then injected safely into my vas deference. it's a crude method, but it'll work. When I ejaculate the polymer will put torque on my sperm and tear them apart so they won't be able to impregnate you and it's easily reversed if we ever want to conceive." Suraci smiled reassuringly then went back to kissing their neck.
Sumas pushed him away again. "What do you mean if we ever want to conceive?"
Suraci sighed "I know it's early for that yet and trust me when I say I have no plans along these lines at the moment, but yeah I would like our relationship to be more serious eventually if we continue to get along so well. You know this isn't just sex for me, right?"
Sumas was a little floored. They knew Suraci wanted to be exclusive, but didn't really think past that. There were too many things going on presently. They weren't certain how they felt about it either. What's more they really didn't want to think about it, because they really didn't have the mental resources. As of yet they still hadn't even processed their miscarriage. Without saying a word they bit his neck just below his ear playfully cleverly avoiding the serious conversation.
Suraci wasn't stupid, he knew that Sumas was yet again using sex to avoid a serious conversation, but as if he could say no and even if he could, he didn't want to push knowing what Sumas had been through. He let Sumas kiss and caress him as he picked them up and carried them to a place deeper behind the waterfall where there was soft glowing moss that pulsed through several different colors: first cyan, then magenta, then green. He set Sumas down gently. "Will you be comfortable on your hands and knees?"
"I should be fine." Sumas said as they got into position.
Suraci grabbed their ass and squeezed it lustfully. It was so round and soft and...squeezable. He gently nipped at it before grabbing his member and stroking them before he inserted.
Sumas moaned desperately. Until Suraci they had never known this feeling. It was the best feeling. Pleasure traveled through them like electricity. They instinctively arched their back like a cat. Suraci gently caressed their low back saying "It's ok, just relax your muscles here."
At first Sumas struggled to relax because relaxing was a foreign concept to them that they had never achieved without the use of drugs, but as Suraci began to massage their low back while rock hard inside them they started to feel their body slowly releasing into the pleasure. Before they knew it they had bent at the elbows and collapsed into their forearms and then their chest as Suraci continued to thrust behind them.
Concerned about their physical condition, Suraci slowed down and, bending over the top of them, asked "Are you ok?".
"Yes..don't..stop." Sumas moaned.
Suraci put his palms down on each side of Sumas and followed the trail of moans until they both came multiple times. After lying there for a while post coitus they decided to return to their temporary camp where a a still brooding Cire was waiting.
---------------------------------------------------------------------------
Cire knew because he wasn't born yesterday, but also because merfolk have very sensitive olfactory receptors. And their pheromones, their fucking, it constantly invaded his senses. Sumas had never produced those pheromones before meeting Suraci and they smelled so delicious to Cire he couldn't help but feel jealous. Sometimes, when he knew they were off fucking together, he'd touch himself for a release just thinking about joining them. He would feel ashamed and guilty afterwards, but couldn't really stop himself.
Upon their return Cire was less cranky, but still refused to apologize. He and Sumas did agree to disagree and he also agreed to continue to help them like they had originally planned. Suraci was soon to return to the base as a double agent, and then he'd have some time alone with Sumas. He didn't think he'd be successful at seducing Sumas in Suraci's absence, but at least he wouldn't have their pheromones always shoved in his face. He grimaced at the thought.
"Cire what's with the face? You look like someone kicked you in the dick." Sumas nudged him.
"Nothing, I just smelled something obnoxious." He dryly responded.
