When the scientist turned back toward the object, he shouted in surprise as a tentacle lashed out and batted the scanner away before wrapping itself around his wrist. He tried to pull away but the tentacle's grip was like iron and it was pulling him closer to a previously unnoticed mass of some sort. A second later, more tentacles lashed out and wrapped themselves around his arms and legs leaving him unable to move. Hiroki opened his mouth and tried to shout for help but a large tentacle made its way into his mouth, quieting his scream to a muffled whimper. He thrashed his head wildly, trying to expel the alien mass from his mouth but to no avail.
He continued to thrash around until he felt more tentacles touching his body. He looked down to see that the pants of his uniform being lowered exposing his lower body to the creature. He watched as a particularly large tentacle approached him slowly as the tentacles that held his legs spread apart. The tentacle wormed its way between his legs and it touched his inner thighs as it worked its way further up. The touch was a gentle a woman's kiss but he was afraid of where that tentacle was headed. The tentacle confirmed his fear as it slid between his cheeks and touched his puckered asshole. He resumed his thrashing trying to get away from whatever this creature intended but the tentacles held him fast. The tentacle slid gently into his ass and began pumping in and out.
He violently struggled against this humiliating, painful violation but even with the adrenaline adding to his strength, he was simply no match for the creature. He became aware that as the creature rammed itself into his ass, he felt some sort of warm liquid being pumped into his body. The creature was inserting a biological agent into his body that would pacify him. The young scientist gradually became aware that his fear was slipping away and was being replaced by a feeling of warmth and a strange sense of arousal. This was confirmed by the fact that he felt his cock beginning to grow and harden. He struggled gradually ceased until all he was doing was bucking his hips in the air, needing relief for his huge hard on. The creature appeared all to willing to aid him in his time of need.
