After an akuma attack on a forest border, Ladybug tried to hide behind a tree to detransform, but to her surprise a weird blob fell on her, and it was quite large, with possibility to easily fit two people inside. It was hiding on top of a tree, which was slippery after the rain. It took care not to knock her onto the ground, partially engulfing her by shoulders and jaw. The rest of it evenly fell over her back, butt and legs.
Ladybug landed safely facefirst into the mud. The blob didn't want to scare her and began calming her, which was by massaging her shoulders. She was surprised by event and the first thing she thought of was her beeping miraculous, but then generally wondered what the heck hit her and whether it's dangerous, since that didn't exactly feel like Chat.
She tried to get out of under it, but failed. It noticed her fear and tried to prove it's nice, by more massaging. It slowly took her in while sending waves of pressure through her entire body, and it felt enchanting. The blob cleaned her face of the mud and left a bubble for her to breathe, ensuring the air is circulated. It has a strong immune system, making everything on its contact clean and fresh, so the air Ladybug smelled was fresh as midnight breeze. Although the blob looks like its made of slime, it doesn't feel so, more like a waterbed or a huge pillow. She felt the pleasant touch and considered it being safe, but had her doubts.
The blob continued massaging her, gracing her arms, caressing her feet, pushing her butt and charming her chest. She could feel how the goo flowed from it, by her neck and behind her ears. It went through her hair and massaged her scalp. She gained trust into the creature and was intoxicated by pleasure. Her entire body was relaxed and caressed. The blob felt how she was malhugged and decided to fully satiate her.
She detransformed and her clothing started blocking the flow, so the blob carefully undressed her. She didn't want to be seen naked, but it felt so good, she decided to gamble. Her clothes were spit out, clean, and she felt way more than in her suit.
Her chest was rubbed in circular motions, goo flowed between her sensitive toes, making her breathe heavily and arch her back in pleasure, so the blob lessened the touch there while sending more powerful waves over her, grabbing her in her stretching, trying to please without arousing her. She never felt better, stretching sweetly through and then relaxing again. She kept her eyes closed and enjoyed her time while her hair flowed freely.
It all happened in less than a minute, and soon Chat was passing, going home to detransform. He noticed Marinette while he passed and was scared for what happened to her and what was that blob. She seemed unconscious and the blob looked motionless, as if it was shot at Marinette by another akuma.
Chat decided to free Marinette from such vulnerable position, fearing for her safety. "Cataclysm!" he jumped toward the blob, which felt his deadly intention and was terrified. It quickly turned its surface into soft waving spikes, as if water over loud stereo, and jumped away with Marinette. She definitely heard Chat and it awoke her, but she considered the blob her friend. She was embarrassed to be seen by her partner like that, but her instinct to protect kicked in. Blob released her, feeling her movement in attempt to get out, but was ready to take her and jump away in case the weird cat means harm to her.
Chat was surprised by its ability to move, but even more so that Marinette chose to stand between them. She covered as much of her body as she could, which conflicted with stretching her arms apart in a stop sign "Chat, wait! Don't hurt it! It doesn't mean harm, it just wants to hug. Please, don't hurt it" She looked innocently at Chat, making his heart ache. Not only he saw and stared at her naked body, but he also misunderstood her private time, wasting his cataclysm in attempt to destroy her special friend. He felt like the worst of scum. "I'm sorry, I thought you were in trouble" He apologized, trying to keep his eyes away from her, but she was the most beautiful sight he ever had, especially with her free hair waving in the gentle breeze.
Blob felt the change in his heart and calmed it's surface, approaching by prolonging itself towards him. "It's alright, I think he wants to know you" Marinette said, looking at its reaction. Chat stretched his hand in attempt to apologetically pet it, but as soon as he touched it, he was pulled in before he could react. He immediately felt the massaging waves, and since he was so deprived of embrace, he was instantly hypnotized. Only his tail was moving. Marinette giggled seeing how much he enjoyed it. "You like him, huh?" Chat didn't answer. In this few seconds he already was cuddled into sleep like a little kitten. Marinette wanted some more hugs, but Chat was going to transform soon while he was asleep, so she put her clothes on and left. "Ok, then, take good care of him, Smoozy"
