Taking care of a raging boner

“I’m sorry he’s so stubborn,” Undine finally muttered.

Seeing her all naked, my dick went hard. Actually, it had been hard for a really long time since I got here.

“It’s not your fault,” Tank consoled, “He’s just looking out for ya.”

“He treats me like I’m still a little girl. He never wants to let me do anything,” Undine sighed, “He just... He just doesn't understand. Someday, I'm going to see what's out there. I want to see other worlds. Does that sound strange?"

"Nah," I shook my head, "I feel the same. There's so much to see out there—I can see why you'd want to go there yourself."

Undine's life somehow seemed very similar to my own past life. I liked this adventuring thing better. If it weren't for complications like Hera and Duncan, then I wouldn't even mind all the shadows. Sadly, Hans didn't seem quite to agree, as he continued to scowl.

"There are no other worlds," he said, shaking his head.

"Yes, there are," groaning, I glared right back at the old mermaid.

This discussion hit too close to home. Undine was like me in a way.

"If my dad won’t help, let’s just deal with these krakens!" Undine said,

"I'll take you somewhere private," Undine said, "But first I can't have Felix fighting krakens while he has such a boner."

Undine took me into her bedroom. She put her fin on my lap and I groped it. I noticed a hole in the fin and looked at it.

"That's my fin hole," Undine said.

I assumed it was similar to an asshole. My hand moved to where her buttcheeks should have been and I slapped it.

Undine gasped.

"How did that feel?" I asked.

"For some reason, it turns me on," Undine said.

Undine reached into my gills and stroked my dick. Soon, I found my hard rod at the entrance of Undine's moist slit.

Our lips met. For a moment, Undine seemed to be unsure of what to do. I probed my tongue into her mouth and she copied the motion. Soon tongues danced around each other. As we made out, Undine slowly lowered herself unto my dick. Up and down, up and down her body went as my dick penetrated her over and over again.

Her tits jiggled each time our lips met. I parted my lips from Undine's and I put a hand on her chest. Squishy, and I loved it.

I was pushed closer to orgasm. Undine fell forwards on my chest. Her head rested on my left shoulder and she cried in pleasure. I was very close to finishing as well and needless to say I felt like a total god right now.

I increased the tempo as Undine moaned, "I am cumming!" I managed to warn before I cummed in her.
