Female parts

"Well, since I'm most comfortable with female organs, could you please retract your penis?" Aaron asked politely.

The intimidating male member withdrew into the alien's body. "Of course. Whatever puts you at ease," Lashu responded.

Aron reached out and gently caressed the fur-covered groin of the interstellar traveler. He ran his fingers around the area, avoiding the sex organ for now. Lashu made more static noises, which Aaron was still finding a little odd. Finally, he got up the courage and ran a finger around the ridge of tentacle-buds at the creature's sex opening. Lashu's static got louder and lower with some bass harmonics that Aaron could feel in his bones.

"Oh, that feels very good, Aaron. You are very gently, er, gentle."

"Thank you," was all Aaron could say, his attention captured by exploring this unusual body. He started using both thumbs to circle around the ridges. The static was replaced by a very low humming from Lashu. Then he cautiously poked his finger into their orifice. It opened easily to allow his digit in, and the interior surface was slippery. He pushed all the way in, to the last knuckle. The inside skin was very smooth and pretty tight around his finger. Lashu's tendrils burst out of their buds and, with a feather touch, stroked his hand. Aaron’s eyes opening wide in surprise, but he relaxed at the pleasant touches on his skin. The alien’s eyes were half-closed, and their inner tissues rippled and pulled at his finger. He curved his finger slightly and twisted it around in a half-circle, rubbing on Lashu’s vagina wall. A high-pitched whistle was emitted from their mouth.

“Oh, that’s good. Your dexterity is very exciting,” Lashu said.

Aaron decided to see how similar Lashu’s sexual response was to a woman. He started pumping his finger in and out of their pussy, the familiar word replacing the stilted language they had used when talking. The whistle resumed, only now their pitch rose rapidly and fell rather slower. He thought Lashu might like more girth, so he added another finger inside and also placed his thumb so it bumped into the ridge of knobs. He plunged in and out swiftly. The warbling whistle matched his pace, reaching a peak every time he hit bottom. He started putting a twist of his hand at the bottom of his strokes, so his thumb would rub hard against the tiny tentacles.

The tendrils became more urgent in their caressing of his hand and harder in their pressure, sometimes grabbing and tugging him, though still very pleasurable. Aaron was getting very horny arousing this alien being.

Suddenly, all noises stopped and the alien’s body went rigid, though he could feel their inner musculature pulsing and squeezing his fingers. He kept up his quick strokes into their pussy. Then the tentacles grabbed his hand and pulled it tightly to the alien body, holding him and not letting him thrust anymore, his fingers trapped in the wiggling cunt. Aaron's arousal greatly increased, perhaps from knowing that he'd made an alien climax, maybe from the increased flow of pheromones. The creature gasped and opened their eyes, looking at him with what he guessed was a look of surprise.

“By the suns of Tragolan, I can’t remember the last time a first-timer got me to orgasm with so little instruction. Are all members of your species so adept at sex?”

“No, but I wasn’t doing much that was particularly special. We use our hands and mouths often, in addition to using our sex organs,” Aaron replied.

“Well, I think this is going to be a very interesting mission on your planet. I can hardly wait to proceed.”
