Willpower wins out

Even though you were unsure if she would get pregnant considering the circumstances, you didn't intend on having a child so soon. She cums, unexpectedly, which throws you off, but with the little bit of will power you have left, you are able to pull out. You cum all over her ass, but thankfully you were able to avoid any mishaps.

Blue slides down, evidently tired. Although you are too, you lay next to her, helping by washing off any stray semen off her voluptuous body. When you're done, you carry her out, leaving her on your bed. Leaving a note to inform her of your leave, you head out, making sure to pay the Pokemon Center lady.
