It gets heavy though...

Your middle starts to get heavy as those massive balls release their load into you. Cokko seems happy, though, so you let her have her way with you. Not that you really have a choice anymore, with how wide your ass is spread, you couldn’t walk off the end of her penis if you wanted. While this isn’t what you expected, it is fun.

“Wow Cokko, this is getting to be really heavy. Are you sure that you want me this big?” you query.

“It may be hard at first, but you will get used to it,” she assures you. “Just like my big dick!”
