"I have stuck many large objects up my butt, I can handle a lot," you retort.
"OK, smart ass, if your ass is so smart, you would already be bent over so I can use my miniscule dick better." You bend over quickly and her tits rest heavily on your back. You feel her hard nipples clearly as they poke you under the heavy weight of her melons.
"Those tits feel great," you comment.
"Your ass feels good too," Jill says as she fucks you. "Ready for a cream filling?"
"I love cream fillings!" At that, she tenses up, and you feel her cream squirt into you, but it definately doesn't fill you. After she pulls out, you turn to see a satisfied smile on her face.
