Some months after formalizing their relationship
Quietly, Wave entered into her boyfriend's home. He had not trusted her with a key, but this was not the first time she had gone and forced his electronic locks. He didn't even care anymore, he had just accepted she would, whether he wanted or not.
She liked to surprise him and then hang out. She then started to hear some grunts. She suspected that he was working out. Good. She loved taking a good grope out of his large muscles when they were pumped. Except, the grunts were not coming from his underground gym.
Was he in another room? It wasn't unthinkable. He was working on these gravity bands, to increase the intensity of his calisthenics workouts. She remembered that one time where she found him doing push ups, and sat on his back. It didn't end well. She followed the grunts, when she heard her name. In grunts too. She wasn't sure how to take this, but she started to follow it more slowly and alert.
It seemed the voice came from his room? She entered and, no, he wasn't there, but now she could hear his ragged breathing. "Wave." She heard it again. Was that a grunt of pain, or a grunt of being tired from working out? She could not decide.
Was he in the bathroom? Again, slowly, she opened the door without making any noise. He was sitting there in the shower part of his bathroom, nude, sweating as if he had run a marathon. That wasn't what made her jaw drop. What did was the size of his cock, which was already dripping sperm from the tip!
She had heard of teenagers joking about how their cocks were like a third leg. She knew to never take those jokes seriously, and Tails wasn't quite there, but it was still insane. It was like a third thigh, about as long as his and about as thick as his tree trunk for legs he had, ones that regularly lifted tons for his routines.
His hands rapidly ran up and down his cock, even his two beefy hands were far from wrapping around his massive middle member. Wave could only watch awestruck. That thing was huge and it was supposed to go inside of women. How could any woman take that?! It would destroy her insides.
Except… she wanted it. It didn't matter if that was the last thing she ever did. She wanted it. It would be appropriate. Why worry about the Babylon heritage? She could just die riding that thing and she would die happy. No regrets.
"Waveeee!" He said while baring his teeth. He pulled his head backwards. It looked like it was taking his absolute everything to resist ejaculating, to prolong the pleasure for as long as possible. Then, his cock expanded, it almost looked like it was going to explode, before shooting a ton of cum across the shower area, reaching the other wall. Wave had to put a hand on her beak or she would have given her location away.
It seemed like the action had taken everything from him, looking exhausted, but satisfied. Meanwhile, Wave was buffeted by the smell of pure testosterone that just overwhelmed her. She could not take much of that, so she got up and walked away. From what she could hear, Tails had started running the water for the shower. He might have thought it was easier to wash up the sperm. Honestly she was just thankful he had not notice her.
Still, after all that, she wasn't getting a good night of sleep, not while she got reminded of his massive dick, or the strong and masculine stench that permeated the short while she stayed there. Not while she got reminded of his massive musculature surrounding her comparably small body. She had to rub herself and her private parts or she would not rest.
