Get Lashu to suck him

He pulled at the alien's body and said, "Lick it off; take it in your mouth. Please." That last was an afterthought of politeness that rose through his lust. His member was still mostly stiff from the exciting strangeness of the whole situation.

Lashu smiled wide. They didn't have a tongue per se, but they knew what the Earthling meant and had structures in their mouth that could perform a similar function. The interspecies ambassador was very facile at adapting their body parts to the sexual practices of different life forms. Lashu leaned in close and surrounded his cock with their mouth. The flexible muscular folds inside were moist and undulated around the stiffness within, wiping off all traces of sperm. The sensation was fabulous; almost like being licked by a tongue that surrounds your whole cock.

The human moaned, "Yes! Now slide up and down the length of it."

Lashu complied eagerly, continuing the exquisite manipulations of their interior mouth surfaces. More cilia around their mouth emerged and flicked around the sensitive areas of his pelvic area and on his penis as it left the being's mouth.

"Shit! You're gonna have me cumming again!" Aaron shouted, completely overwhelmed by the feelings his body was channeling into his brain. In his **** lust, he grabbed the vaguely human head before him and pounded his shaft hard into the alien's oral cavity, fucking their head vigorously.

With no gag reflex, the alien slut took the skull-fucking with great enjoyment. They knew intuitively that the human was reacting with the very powerful sexual responses that come only when a being is fully engaged in the sex act. The ambassador was pleased for producing a truly species-normal sexual reaction. They had conquered the human's defensiveness at meeting an extraterrestrial being.

Aaron plunged his cock furiously into the foreign mouth, and, in another dozen heartbeats, his cock exploded in a geyser of spunk, squirting into the creature's mouth and down their throat. He crowed to the ceiling in ecstasy. His knees finally collapsed, and he fell onto the couch behind him, his manhood popping out of Lashu's mouth.

"I've never cum that close together ever. You are amazing, Lashu," he said, gasping for air.

Lashu's throat moved in an unusual way that Aaron decided was the alien swallowing. "Your gametes taste interesting. I like the texture too," they responded.

"Most women say they don't like the texture or taste," said Aaron, still catching his breath. "That mouth of yours will also make you popular. Those tentacles and the other ones on your cunt and hand are the best."

"Cunt? Is that my female sex organ?"

"Yes."

"Are you ready to explore each other more?" the interplanetary visitor asked with interest, filing away the terminology in their memory.
