When all the water had drained out of the tub, Atsushi placed his hands on En's chest, pushing him away lightly. Finally released from his boyfriend's kisses, Atsushi panted heavily as he gasped in air and said, "En-chan, shouldn't we refill the bath? I thought we were going to test other bubbles."

En regarded him with a serious face, then nodded once, standing up and extending a hand out as assistance. As he stood, Atsushi's body brushed against En's erect cock, and he looked down, startled by the sensation. His face flushed red as he noticed that he was also hard again. En reached in between them, murmuring, "You get like this just with some kisses, huh?"

"Th-that's because...it's En-chan...and I've wanted you for so long…" Atsushi's voice trailed off in a gasp as En reached between them and grasped both of their cocks in his hand, squeezing them together lightly. "Nnn...En-chan…"

Atsushi shuddered as a low voice replied, "Yes?" En began stroking up and down with firm but languid strokes. It was all Atsushi could do to cling onto his boyfriend's arms to keep himself upright as his breath was reduced to short gasps. Huskily, En whispered in his ear, "I'm going to refill the bath. Can you get something else to put in it?"

Not trusting his voice, Atsushi nodded, and reluctantly stepped out of the tub and out of En's embrace. Crouching down next to the discarded bag, he dug around in it, sifting through the remaining products as the sound of running water cascaded into life behind him. He settled on the bag of miniature bath bombs, and opened the package. There were six little purple balls inside, but he decided to be conservative and pulled out just one. It felt strangely chalky in his hand as he stood and offered it to his boyfriend. "Here, En-chan, let's try this one next."

En turned his head to examine the ball. "What's this one?"

"It's a bath bomb. It's supposed to fizz in the water."

"Hm. Yeah, let's use that." Reaching out, En plucked the ball from Atsushi's fingers, dropping it into the half-full tub. They both leaned over and watched the little ball bob in the water. It started fizzing violently almost as soon as it hit the tub, and both boys let out appreciative noises as a purple halo of foam started to spread out on the surface of the water.

"Do you want to get in now?"

Atsushi looked at the other boy. "I don't know. Are we supposed to wait until it's dissolved?"

En shrugged. "Who cares? It'll be in the water either way."

"Hm. I suppose you're right." Atsusi leaned over the side of the tub and dipped his toes into the fizzing lavender ring. "Ooh, it tickles!" he exclaimed, withdrawing his foot quickly. After getting over the surprise of the fizzy feeling on his skin, he placed his foot into the water, then the other, before sinking his body fully into the tub. En entered the opposite end, turning off the faucet before he sat down to settle himself into the water.

For a few moments, they both watched the remnants of the bath bomb as it rotated haphazardly, dissolving at an incredible pace. En poked the depleting ball with his finger, and raised his eyebrows. "Oh, it does tickle."

Atsushi laughed. "I told you!"

En looked up at him, and Atsushi felt a little shiver run down his spine. There was an odd heat in the gaze that was being directed at him. Before he had time to think about too much, however, he was being pushed back gently against the side of the tub, and En's lips were descending on his. Heat spread from their joined mouths, down his abdomen, blossoming throughout his body. He moaned quietly into the kiss, allowing himself to sink into the warmth their bodies were generating.

He vaguely heard some rustling noises off to the side, but couldn't be bothered to pay attention to anything that wasn't En. Timidly, he probed his tongue inside of En's mouth, twisting it around to explore this new area.

Suddenly, he felt a strange sensation on his lower half. His eyes flew open, and he jerked his head backwards. Looking down, he saw En holding a new bath bomb against his dick.

"E-En-chan, what are you doing?"

"I wanted to see if this would feel good for you." En watched him closely as he started to rub the ball in circles.

"Aah...it feels...strange…" The fizzing sensation against his shaft was oddly intense. Atsushi wasn't sure if it felt good or not.

"Hmm, maybe you'd like it down here better?" En rolled the ball down the shaft of Atsushi's cock, skimmed over his balls, and then pressed it gently against his ass.

Atsushi's hips bucked upwards violently, sloshing water everywhere. "Aahn!" he gasped, and his hands shot out to anchor themselves on his boyfriend's arms.

En's eyes lit up, and he smirked. "Ah, that seems to have gotten a reaction out of you. Even though we've only had sex once, you're already feeling it here?" He pushed the fizzing ball a little harder, and Atsushi moaned.

"Please, En-chan...that feels weird…"

"All right, I'll make sure it feels good." He began slowly pulsing the ball against Atsushi's entrance, assaulting him with sensations. He didn't even notice that En was getting yet another bath bomb until he felt it pressed against his dick. En rolled the second ball around his head with his palm and said, "I didn't forget about this. You want to feel good here too, right?"

The feelings were overwhelming, and he felt like he was melting away along with the bath bombs. He managed to gasp out, "En, this is...no fair. I want you…"

His boyfriend's voice echoed in his ear, and he realized En was leaning over him. "Where do you want me?"

"In...side...please, En-chan!"

Finally, the sweet torture of the bath bomb on his lower half ended as abruptly as it had begun. But Atsushi wasn't given a chance to recover, as he immediately felt the head of En's cock prodding his hole instead. He spread his legs a little wider to accept him. Smoothly, En pressed forward and slid his length inside up to the hilt.

When he was fully inside, he smiled down at Atsushi with an almost wolfish grin. The expression startled him, as he had rarely seen En with such an expressive face. The smile didn't diminish as En said, "I went in really easily that time. It must be because of my cum inside of you."

Atsushi gasped as his boyfriend withdrew and started to pump himself shallowly in and out. Between thrusts, he said, "En-chan, what is going on? I never knew you were this…"

"Possessive?" En finished the sentence for him, punctuating it was a particularly harsh thrust. "I've wanted to do things like this to you, but I always tried to hide it. Didn't you say so earlier, too? It's because it's with you, and I've wanted to do this to you for so long. So very long, At-chan." He dipped his head down, burying it in Atsushi's shoulder.

Smiling, Atsushi looped his arms around his boyfriend's neck. "I understand. And don't worry, I'll accept every side of you. So you can do as you please with me from now on."

En paused, and Atsushi momentarily wondered if he was going to pull out. Then he began to stroke violently in and out, pushing Atsushi against the wall of the bath with the force of his motions. Atsushi's voice rose in a keening moan, and En growled in his ear, "You'd better be prepared to keep that promise, At-chan. Because there's no way in hell I'm ever letting you go."

Unable to form any coherent words, Atsushi simply nodded and tightened his hold around En's neck. He wouldn't, either.

It didn't take long for En to growl, "I'm going to come. Can you come for me, too?"

Atsushi nodded as En's hand slipped around his dick, stroking it urgently in time with his thrusts. What really pushed him over the edge, however, was the feeling of En's cum pooling inside of him. With a particularly loud moan, he felt his own release, and shuddered repeatedly until it was finally over.

Gently, En pulled himself out, and Astushi gave one last shudder at the motion. Breathing heavily, he looked up at his boyfriend and gave him a crooked smile. "Wow, En-chan, you really have been holding back, haven't you?"

En's face was back to his normal bland expression, although there was still a spark in his eyes that he couldn't quite seem to suppress. "I told you. I've also wanted you for a long time. I don't know how you can expect me to be calm when you finally tell me you love me."

Atsushi grinned. "So you're saying that every time I tell you I love you, it will rile you up?" He leaned in close to his boyfriend, close enough that their lips were almost touching, and whispered, "I love you, En-chan."

The fire smoldering in En's eyes ignited into an inferno in an instant. "At-chan, are you stirring me up on purpose?"

"And if I am? What are you going to do about it?"

En smiled, and closed the distance between them, kissing him intensely. Atsushi kissed him back as a small corner of his mind wondered how long it would take for them both to be satisfied. But it didn't really matter. They had plenty of time (and plenty of baths) to find out.
