America Chavez continued to follow Black Widow across the plaza where the vines had attacked her. Gwen remained unconscious and was carried on a stretcher by two robots, America kept glancing at the young superhero with a guilty conscience. "It's not your fault!" Said Natascha suddenly and abruptly, Chavez winced and felt caught. Dejectedly she looked at the ground in front of her, "If I hadn't looked over the piece of debris, then..." "They had scented you before you entered the field. It's not your fault!" Said Natasha and turned to her and smiled. Embarrassed, America looked away, she still had a guilty conscience, but it had lessened significantly.

They arrived at a subway station entrance, the sign was missing. Black Widow stopped and spoke into a mic attached to her sleeve, "It's us disable the weapon systems!" A hum sounded from the entrance and they continued on, slowly walking past turrets and flamethrowers until they came to a steel door where the turnstiles had once been.

With a click it swung open and another robot stood in front of them. "Thanks Javis!" Said Natasha and went inside.

America marveled as she stepped over the threshold, guns, computers and lots of gadgets she couldn't identify. "Welcome to our shelter!" Said Natasha and put her guns on a table. Gwen was carried past them and placed on a hospital bed.

America stood there and looked around in amazement, "Hello Natascha, is this our newcomer?" A voice said and Wanda Maximoff stepped out of the shadows of a corner, Maria Hill also got up from her computer and came to them.

"Yes, that's the young lady Gwen dragged along." Natascha said and put a hand on America's shoulder. "What is your name?" Hill asked, eyeing her critically. "That's right, I haven't found that out either!" laughed Natasha. "My name is America Chavez! I ended up here by accident!" She said and looked everyone in the face one after the other. "And where do you come from?" "That's a longer story." America replied to Wanda's question. "We have plenty of time, so where are you from?" Hill asked in a commanding tone. Natasha rolled her eyes and patted America's shoulder encouragingly. "So …"

America began, telling everything as she had told Gwen before.

While she was talking, they sat down in a seating area. After the tales of America, no one said anything. "That explains the energy curve I measured twice yesterday." Said Maria Hill, assuming the dates of the appearance and attack on the Trees of America. After a few questions from Wanda and Natascha, a robot showed Chavez their night camp. It was a small room, accessed directly through a hole in the wall. The walls were poorly clad with stones so that the plant world could not penetrate, a small improvised shower and a chemical toilet were ready in a corner. After the day's exertions, America freshened up, after a cold shower she slipped into an army jumpsuit that Natasha had given her. She gave her clothes to a robot that would clean and repair them. Now she lay on the bed and reviewed the day, not noticing that a thin vine pushed through a tiny gap at the foot of her bed and dropped a small seed. Realizing she was getting sleepy, the conversation and everything had gone on all day, she covered herself up and snuggled up. It didn't take long for her to fall asleep.

Natascha stood in the tunnel of the former subway station, but this had been converted into a shooting range, which was perfect considering the straight tunnel. The tunnel went dead straight for at least 500 meters before turning slightly, they took advantage of that and built a thick concrete wall at the end so that nothing from that direction could surprise them. They did the same in the other direction, building individual rooms and rooms into the tunnel walls up to an area that had collapsed. To be on the safe side, they had built a concrete wall there as well.

Natasha, raised an assault rifle and fired at targets created by nanobots, a holdover from Tony Stark's inventions. After the third clip, she put the rifle down and grabbed two handguns. Now she walked around the barrier, a signal for the nanobots to simulate a fight.

The simulation started as soon as we got to the start position. Black Widow jumped, kicked, and punched her way through the fictional enemies until she knocked them all out and landed on the ground in her usual pose. Her breathing was a little faster, but regular, suddenly listen a noise behind her. She slowly straightened up, "Light!" She said loudly and the lights went on in the entire tunnel up to the concrete wall. She continued down the tunnel cautiously, her black suit making no sound as she moved. Almost casually she reloaded her guns, now she was standing in front of the wall and had to be exact. No cracks, no holes or anything like that. "Probably a stray rat." she murmured and turned around. Right in her field of vision, a small dried tendril fell from the tunnel ceiling and landed on the ground in front of her. She slowly crouched down and picked them up, "What the…." Suddenly one foot was pulled away and she was able to turn around to keep from falling on her face. Instantly their gun was drawn and they accurately shot the tendril that had wrapped itself around her ankle. She quickly spotted the seed pulsing on the ground and aimed her weapons at it, but it quickly catapulted itself out of the way with a tendril slash. The bullets splattered the concrete floor and dust flew into the air. With a quick movement, Natascha rolled onto her feet again. She raised her hand to her mouth to sound the alarm when two tendrils attacked her. One was riddled with bullets, the other snatched one of her weapons from Natascha's hand and threw it far into the tunnel. Natascha knew what that was true, they called those seeds Tickelseeds. They were quite harmless, they only survive for 30 to 40 minutes and then dry up, but they were annoying and had something like intelligence. She and the others had often had to do with it and until now they were always able to fend it off, but only because they had discovered it in time. This time it was a little surprising. The dust settled and Natascha looked around searchingly, suddenly a thin tendril wrapped itself around her wrists and one around her ankle at the same time, with a quick jerk they brought her out of balance. "Fuck!" Natascha escaped as she landed hard on the ground, her last weapon arcing out of her reach. Before she could get to her feet, she was lifted upside down, quickly twining two more tendrils around her wrists. Desperately she pulled at her bonds, but it was no use, the tendrils slowly pulled her apart until she had both arms over her head. While they were doing this, they turned Natascha so that she was facing the floor on her stomach. She gasped with the effort to get out of the bonds. Now she felt a tug on her boots, she tried to press her toes against the sole to keep them from coming off and it worked. Now she felt how razor-thin tendrils slipped into the sleeves of her suit, she noticed the fine hairs on them and how tingling they paved their way. Natasha gritted her teeth as the first reached her armpits and the tickle stimulus began. The corners of her mouth twitched uncontrollably, not wanting to admit it tickled. More tendrils joined them, making her chuckle and twitch softly. Desperately she had to watch as another e ranke pushed into her cleavage and made her squeak. "Ohhh my god!" She moaned, giggling as the tendril parted in her cleavage and began exploring her bra. She realized embarrassingly that this wasn't exactly uncomfortable, even if it tickled, but the realization was short-lived as tendrils continued to work their way into the sleeves and neckline. Her laughter erupted suddenly and she squirmed like a fish to escape the feeling. Suddenly she became aware of something else, she felt tendrils crawling into her boots. Laughing, she tried twisting and turning to stop them, but it was in vain. She laughed out loud as the vines slowly crawled into her socks and wished she should have let her boots off. Due to the limited space in the shoe, she could not move her feet a millimeter. With tears of laughter she felt them slowly wrap around her toes, every attempt to counteract this was counteracted with extreme tickling. By now, dozens of these tendrils were threading through her suit, curling in her belly button and carefully exploring her pubic area. When a tendril slowly snaked its way through her butt crack, all the dams broke. The strong Black Widow screamed at the top of her lungs and laughed so hard her head was almost the color of her hair. The initial pleasure as the tendrils teased her breasts and labia had faded and made way for pure torture.

While Black Widow endured her ordeal, America didn't fare much better.

America Chavez was sound asleep, one of her bare feet hanging over the foot of her bed when the tickelseed started pulsate and the first tendrils broke out of it and slowly stretched and stretched. The first tendril quickly discovered America's foot and carefully felt along the sole, the foot twitched slightly and the toes spread. That didn't stop the tendril from snaking up and down the sole until America giggled and pulled the foot back under the covers in her sleep. Now the Tickleseed came to life, more and more tendrils sprouted up and slowly began to wrap themselves around the still sleeping America. When she tried to turn around, she woke up when she couldn't. Confused, she opened her eyes and tried to move. Then she felt something preventing her, she wanted to scream in panic. But while she was still catching her breath, dozens of tendrils wrapped themselves around her head in a flash, so that her mouth was closed and she could only make soft noises. Slowly her body was lifted, the blanket slid to the floor and she saw the extent of her immobility. Her arms were fixed to her sides and her legs were tied together in several places. Her eyes circled in panic in their sockets, she felt how some of the tendrils stroked her bare soles. It wasn't enough to make her laugh, but she already felt the urge to giggle, and in her desperation she wiggled her feet to thwart the strange plant. She succeeded again and again and the feeling stopped short with each movement, suddenly she saw that one of the tendrils around her ankles parted and crawled over the tops of her feet. Any movement she made was useless now, until finally the vine wrapped itself around her big toes and she felt her feet slowly being pulled back. America tried to counteract this with all her strength, but after a short time one of her feet was stretched tightly backwards. A few moments, and some effort later, the second foot was also in this position. Growling, she announced her displeasure and suddenly squeaked when the tendrils now drove over her tense and stretched soles. In contrast to before, it tickled much more, which made the young woman giggle unintentionally, which could only be heard very quietly through the gag. Apparently the tendrils had had enough, they slowly began to slip into their overalls, and America giggled in panic, noticing the tendrils of the dunes on their bare skin. When the tendrils in her trouser legs reached the back of her knees, she felt an intense tickling sensation, the plant felt it and stayed with a few tendrils at this point. America's giggle turned to laughter as her concentration slipped over the emotion. Suddenly, a vine rose up right in front of her face and then slowly lowered again, giggling and laughing, America followed her with her eyes. That tendril was now tapping against the zipper, America's eyes widened in horror and he shook his head. The vine ignored the gesture and slowly unzipped it. Now dozens of tendrils began to slither into the large opening, America's mind was racing, all over her body she felt the tendrils and this extreme tickling stimulus. Added to the feeling of torture was a feeling of lust she couldn't place. The tendrils not only explored the ticklish regions, but also the erogenous zones. They caressed her nipples and explored her pubic area in great detail. But the thrill of the tickling outweighed it, her head was now bright red and her thoughts drifted while she kept rolling her eyes. Suddenly the door to their quarters flew off its hinges and a shot rang out in the small room again. All of the tendrils withered instantly when the Tickelseed was hit and America fell onto her mattress. The last thing she saw was Maria Hill's worried face then she fainted.
