The tentacle went down her back, zigzagging around the spine, slowly, until it reached the small of it. There it circled a bit before encircling the naked waist and pulling her closer to him.
She gasped for air as another tentacle let go of her nipple and spiraled down her breast, before descending the body, following her curves until it reached the thighs where it gently but firmly pulled her panties off.
Her body shivered when the third and forth tentacles, that had been innocently resting against her legs, both started climbing them from the inside, always slowly, but surely.
Her lips tried to say something but all that came out was a gargling and heavier breathing has the green appendixes finally touched the inside of her body .
Whatever resistance she might have had to this situation was long gone and she now gave herself fully, the small doubt that had been there at the beginning now gone : making love to a alien was good, and getting better by the second.
She kissed his mouth again, his saliva was still sweet but not so overwhelming as it had been before, threw her arms around his slim body, noticing how his skin was now almost moist, warm and inviting. His tongues played with hers and kept her from screaming her pleasure.
He rested her on the bed and caressed her hair, gently, before kissing her one last time and returning to his ship, not having uttered a single word, not even inside her mind as he had done before.
"Wait!" - She shrieked as he climbed out of the window.
He turned his head around, not moving his body and she asked, her voice more controlled - "will I ever see you again?"
He was already inside the small vessel, it's lights starting to shine, when she heard, again inside her mind, that grave voice that had sent shivers down her spine : "I'm sorry."
