More cock!

Kako pulls her face from your butt. Her pendulous breasts slide out a bit as she pulls back. She leaves her arms in still, fondling her nipples. "How about we add some meat to this titsandwich? It's the only way to get the special sauce in."
"Yeah, but I'm guessing I can't take your log in me with those tits too!"
"Don't worry, my tits are squishy. My 'log' as you put it will push the titflesh out of the way. You probably will have no trouble at all. At least not until I cum for the...what's our limit? Ten? Well something like that!"
"Uhm...I don't think..." Kako sneaks her cock into your butt before you can finish. She was right, it wasn't so bad. She fucks you from behind hard, her arms working her shaft. Her balls swing and collide with yours at every thrust. You spread your legs a bit wider to give those sexy cumfactories of hers plenty of room to smack into your own.
"You like that? My balls?" She makes sure to pull back farther and thrust deeper so her nuts really hit yours good. You moan in pleasure, so she keeps it up.
"These things like to be treated roughly, I think," you tell her.
"That's a tip for you for the future: the bigger they are, the more you can knock them around!"
