The creature's tentacles encircled Lucas' ankles and wrists lightly, as if to prevent him from escaping. But that is unnecessary, as the pheromones the creature pumps into the air are designed to ignite uncontrollable lust in its victim. The restraints were just to stop him from touching himself. Lucas couldn't even form the thought to escape with how much he needed release right then.
Tentacles crept between Lucas' spread thighs, aiming for his virgin anus. At first dozens of small, finger- like tentacles caressed and teased his perineum and anus, Lucas' erect cock dripping precum down. Then a narrow, much longer tentacle joined in.
Eventually his outer sphincter relaxed under the caressing touches. As if the creature had been waiting for it, it's long tentacle slithered into the relaxed orifice. The tentacle was slick with lubrication it continuously excretes and slipped inside the virginal hole with almost no resistance.
It took Lucas' lust driven mind a few seconds to even register that he was no longer an anal virgin. But before he could even think to struggle, the tentacle caressed his anus from the inside, drawing a moan from Lucas. His anus reflectively tried to tighten around the intruder. The sensation alone almost brought him to orgasm, feeling his hole stretched open around a slippery, slimy intruder.
Inside his ass it began slithering around, getting acquainted with Lucas' anatomy. It tickled as it explored every inch of his most sensitive place, lubricating as it went.
Other tentacles joined in exploring his body. Two found his testicles and began gently massaging the precious orbs in their tight sack, encouraging them to produce more of their salty cum and precum. Another twisted around his straining member, constantly stimulating him.
Lucas was on the verge of orgasm when the tentacle inside him pulled out.
