A deep red blush spread across his face as he felt a slimy tentacle make its way through his panties and into his virgin anus that had only been intruded by his middle finger. He whimpered as it started to move. "S-stop," he whimpered shyly, "I'm sensitive down there. . ." the blush continued spread across his face as he felt a slimy tentacle make its way through his panties and into his anus. He whimpered as it started to move. He could feel precum already dripping from his hard member. "Stop! I'm gona cum!" The tentacle continued to ravage his virgin anus, despite his pleas. As he neared orgasm, the tentacle started to spurt a slimy liquid inside of him. He wasn't sure whether to be disgusted or turned on witht he beast filling his anus with its cum. He quickly reached orgasm. The hot, white liquid shot from his small penis, and his body grew stiff and rigid, quickly becoming covered in goosebumps. He moaned as the last burst of cum dripped out of him and the beast pulled out of his anus. He then collapsed on the bed with a sigh.
