Sparks had calmed down now and was able to think rationally. "So how are you able to generate so much cum?" She asked curiously, enjoying the gentle touch of his strong hand.

John got up from the bed and quickly stripped off his clothes. He knelt at her side, so she could study his anatomy.

“Wow! Four balls!" Sparks exclaimed as she examined him closely.

“May I?" she asked, her curiosity peaked.

“Sure, go ahead" John replied encouragingly. The pale girl reached out tentatively and began to feel the four heavy spheres, taking each into her small hand in turn. "They're so big!" She said in wonder.

“Just how much do you cum?"

“I've never actually measured it, but at Least 4 pints I would guess” he pondered "More if I'm really turned on".

“That's amazing" Sparks said in wonder. "So what are you exactly?" she asked him bluntly.

John laughed at her question good naturedly “I'm half human, but I've no idea what my father was. My mother disappeared shortly after I was born, so I never got to ask her about him" he explained.

“Well I think you're pretty cool, whatever you are!" Sparks smiled at him, as she ran an exploratory finger along one of his pointed ears.

“Thanks, I think you're pretty cool too" He said smiling at her warmly.

Sparks laughed at that.

“So when do you want to fill me up again?" she asked curiously.

“How about we wait until your tummy goes down, then we can take it from there" John suggested.

“Besides, I'd Like to take you on a tour of the ship and it's going to be harder for you to get around if you're carrying a massive load of my cum" he said, stroking her rounded Little tummy again.

Sparks looked up at him shyly and placed her pale delicate hand on top of his as he caressed her swollen abdomen.

“I think I finally understand why Alyssa and Calara love this so much"

“Really? Why's that?" John asked, curious.

“It feels like you own me" She said quietly, as she blushed prettily “that I'm just here to service you whenever you need. I feel totally submissive and its very arousing".

"Do you Like the thought of being my property?" He asked her, finding this conversation surprisingly exciting.

Sparks bit her lower lip and then looked directly into his eyes “Mmm-hmm" she nodded.

"Good" he said confidently.
