After several minutes of scratching the spot through the fabric of his swimsuit, Lucas slipped his hand in his swimsuit to examine the spot. And he felt something weird just above his cheeks. He was still laying on his chest and couldn’t see it but he felt a tiny bump and some hair on it. At first he thought the bump was some sort of pimple and the hair was just because he didn’t shave his butt in ages, he just scratched it with his nails and the itching was gone, probably temporarily.
He didn’t think about it more and resumed his sunbathing. But shortly after, the itching was back and worse than before along with a weird stretching of his swimsuit. He was about to slip his hand in his swimsuit once again but before it reached his swimsuit, his hand bumped into something fuzzy. He thought he had a bug on his back and tried to pick it up but when he pulled on it, he felt a sharp pain where the itching was. The pain startled him and he sat on his butt to see what was wrong with his butt and what he saw freaked him out. He saw a a hairy growth of flesh just above his ass. Lucas was terrified right now, he didn’t know what was happening to him. Lucas tried to pull that thing in his swimsuit but the thing began throbbing and elongating at an alarming rate. He tried to stop I but the thing was growing right in his hand no matter what. He was terrified and humiliated, and before anyone around him could notice the bulge growing in the back of swimsuit he packed his stuff and ran away toward the cliff where no one went because it was too shady.
When he was sure no one could see him, he went back to examining this thing again and he noticed it had grown even more, going from a ½ inch to an awful 4 inches, and it was still growing at the same pace. The thing kept growing and tried to escape Lucas’ swimsuit. The panicked boy tried to prevent it from moving but each time he tried the thing seemed to '' get angry '' and grew even faster. At some point Lucas couldn’t stop it from escaping end he felt the hair brushing against his asscheeks as the thing moved downward through the hole of his right leg.
Lucas finally understood what it was. It was a monkey tail !
« What the fuck is happening to me ? Is it because of that bitch from earlier ? » he told to himself.
Lucas was overwhelmed with feelings, he was terrified and mad.
But as he was freaking out, the tail was still growing. After only a few seconds, the tail began moving on its own brushing sensually against Lucas abs and thighs. The tail had stopped growing at this point and it was now harassing him. The boy tried to push the tail away but the more he tried to push it away the more it insisted to caress him.
