Jerk Off

"Good." Kalli says as she pulls out a cup from the desk she's sitting at. Alex takes it as Kalli says "I assume you'd like visual stimulation?"

"Yes."

Kalli opens her suit up, revealing her massive chest mounds. Alex's jaw drops with surprise, to which Kalli says "Thought you'd like them."

"I sure do." Alex says as he undoes his belt. He then pulls down his pants as Kalli awaits to see his penis, interested to see how it compares to her fellow kind's anatomy. With his pants down around his ankle, Alex begins playing with his semi-erect cock. Kalli asks him "When was the last time you had intercourse?"

"Earlier today." He replies.

"So I assume you're fairly sexually active?"

"Uhh, actually the last time before that was about a month ago."

"So you have sex once a month?"

"Since I broke up with my girlfriend, yeah I guess."

"Okay." Kalli says as his cock begins to stiffen. Kalli proceeds to ask "How long is your penis?"

"Six and a half inches."

"And that's above average?"

"Yes." Alex says as he begins stroking. Kalli licks her lips at Alex's display. He doesn't waste time, thumping his hand up and down his shaft. He then asks "So what about your kind? What size are their cocks?"

"Yours would be of average length." Kalli replies as she begins to play with one of her hard nipples. The sight of an alien masturbating over her was fascinating. She's the first of her kind to have a sexual interaction with a human, in an attempt to play god and save her species. There is also the fact that all the men were back at home fighting each other, and that she hadn't been with a man of any kind in over a year.

Kalli patiently waits as Alex continues to stroke off. She hadn't expected him to last long, but he proved to be much more enduring, so she asks "Would you like to touch my breasts? I can hold the cup."

"Sure."

"Go ahead." says as she takes the cup away from Alex who then begins to knead one of her massive breasts. He'd never had the chance to play with boobs this big, human or alien. Nothing about them felt unnatural, and if he had his eyes closed he wouldn't be able, nor care to tell the difference. That's when he feels his balls tighten. He says "I'm gonna cum."

Alex ejaculates into the cup, providing a sample for Kalli. She puts the cup on her desk before saying "Thanks Alex."

"No problem. So what happens now?"

"I'm assuming you'd like to rest? This has been a lot to take in." Kalli zips up her suit, much to Alex's disappointment.

"Yeah, that'd be great."
