Go for the body.

Shooting forward, you tackled the raichu around the midsection, taking her down to the ground with you atop her. You scrambled to spread her legs, hoping to be inside her before she could react. As you had hoped, Rita was taken off guard by your sudden rush and you managed to bring your cock to bear on her pussy and slide swiftly inside of her.

Rita moaned as your length bottomed out inside of her and you had to bite your lip not to do the same. It felt good being inside of the little pokemon. Placing both of your hands on her shoulders, you held Rita down as you proceeded to drill into her wet tunnel.

"Fuck..." Rita moaned, struggling lamely against your efforts. "Your cock feels even bigger than it looks..."

You couldn't help but grin as you brought a hand to Rita's throat. "Imagine how it'd feel in your tight ass?" You teased her as you pounded into her.

"Why don't we find out?" Rita panted, giving you a sly look. This had to be a trap, you thought. But the invitation was very tempting though.
