All the way inside her.

Despite being on edge, you have no intentions of stopping now. Your dick keeps slithering in and out, sliming its way through the ever-tightening insides of Blue's sister. It all comes to a halt as you thrust in one last time, going balls-deep into her, letting loose all the baby batter you got.

"Ah! No...Red! You can...you can't cu... AH!" Her cries of objection are interrupted by her own pussy clamping down as hard as it can as a result of an amazing climax. "Ah! AHHHHH!...Guh, huh..." The powerful screams quickly tone down into mere whimpers and pants, befitting the exhausted girl in front of you.

After a few seconds, Blue's sister musters up enough energy to give you some angry eyes and start lightly hitting you on the head. "No! No! No! You shouldn't do that jerk! Don't you know how rude it is to cum inside without asking! Learn to use your words! Jerk! Jerk! Jerk!" Following the adorable onslaught, both of you get up and get your clothes back on (in her case, what little she had to begin with). "Hey, Red?" She smiles and runs up to you. "That was a lot of fun; make sure to come back and visit sometime, okay?" She finishes with a kiss on the cheek.

Feeling the time's right to leave now, you walk back out into Pallet Town.
