He nodded.

The smile grew wider on Yukio’s face. Ellie’s eyes seemed to sparkle. Colossus realised, if he really wanted to, if he had really tried, he could have freed himself from the chains. There were moments where Yukio’s powers didn’t hold him, he would’ve been able to time it enough to break free and escape. But instead, he didn’t. He watched Negasonic reach out and grabbed his cock. He felt electricity, but not from Yukio this time. Ellie’s soft skin against his steel was a jolt of unexpected pleasure. She could barely wrap her fingers around the girth of him, her fingers unable to meet where she held him.

“Oh my god it’s warm,” she said, surprised, and she gave him a squeeze. It was hard, but also … soft. It was difficult to describe. It wasn’t exactly flesh. It had a give to it, not quite spongey, not like soften metal, but still firm. She could feel his blood pumping. The thing throbbed. It was completely different to the metal dildo. This was living metal. Organic steel. He was shivering as she kept feeling up and down the long shaft. The realisation that all of his nerve endings still worked made Ellie smile. “Does that feel good?” she asked him.

Colossus was breathless because he forgot how to breath. Only when he heard Negasonic’s question, saw the girl looking up at him with his cock in her small hand, did he know to inhale.

“Yes… good…” he muttered. This got a laugh from Yukio who shuffled up closer as well.

“Let me try,” she said, grasping onto the base of the iron erection and getting another vocalisation from the giant. Ellie let go to watch her girlfriend play with their trainer’s cock. “It’s… hot…” she said. “And smooth… and hard…”

“Bozhe Moi,” he grunted as Yukio began to stroke him. Her grip was just firm enough to send waves of amazing sensation up through his entire metal form. The teenage mutant discovered that his skin here functioned almost like normal skin, her hand not chaffing from the metal or the grooves at all, just moving up and down smoothly.

“Look at that, Negs,” Yukio gasped, pointing to the shiny tip of the colossal cock. Colossus made another strained noise as Ellie’s pretty face leaned in and he could feel her breath. “Pre-cum,” Yukio explained. Their eyes were fixed on the growing bead of liquid she was slowly milking out of him, Negasonic licking her lips instinctively. “Taste him,” the perfect girlfriend suggested.

“Ellie…ahhh...” Colossus began, but was at a loss for words when she went forward and licked the bead of pre-cum right off the crown of his cock. Ellie’s soft tongue lingered against his hard helmet, then her upper lip closed down and soon she was trying to drink from him.

“Mmmm…” Ellie hummed, her enjoyment apparent. The taste was sweet and metallic, not surprisingly. She loved the flavour of his skin. Her tongue explored more of the steel schlong, the girl bringing her mouth lower, sampling each segmented inch of him with a thorough, wanting, lust. She got to his metal scrotum, which was wrinkled and moved freely, like a mesh sack. With easy instincts she put one in her mouth and gently sucked.

“Lenin’s ghost! This is… Yukio!” Colossus’s head was spinning and he was barely able to keep up with the visuals. Now the girl with pink streaks in her hair had her lips on his thick rod, kissing and sucking the side of this dick and moaning in amusement. “It’s so weird,” she mused, looking up at her mentor’s wides eyes briefly before going down and taking the tip of his cock into her mouth. He could only groan as the girl’s mouth stretched and she started to suck, started to bob. After few seconds of this amazing sensation Piotr felt Ellie’s lips and nose leave his sack.

“Wow… look at her go,” she said, watching as her girlfriend gave head. At this point the hero wished he had freed his arms because he wanted to put it on the back of Negasonic’s head and put her lips back onto him. In fact… he wanted to feel the inside of her mouth like he was currently feeling Yukio’s. Her drool slathered him down to his shiny balls and he threw his head back, allowing his enjoyment to loosen. She then got off him with a pop and a laugh.

“I bet he wants to fuck your mouth, Elle,” she said, earning a soundless gasp from the short haired goth. Yukio grabbed Ellie’s shoulder and moved her front and center so that she would have complete access to his dick. “Would you like that sir?” asked Yukio politely, looking up at their teacher. Colossus swallowed hard, the cringe he felt at the honorific address used was nothing compared to the thrill that vibrated from his cock to his core. “Would you like to fuck my girlfriend’s mouth?”

Ellie’s mouth fell open automatically and Colossus could only stare at the offered hole, her pink tongue hanging out obscenely.He suddenly worried about knocking out her perfect teeth because all he wanted to do was ram himself down her throat.

“Fuck my mouth,” she told him, soft but stern, then opened wide again. Not one to leave a lady hanging he lowered himself slightly and tried to point his cock where it wanted to go. It was difficult not having his hands, but Negasonic was eager enough to find him the rest of the way. Her tongue started up the underside of his shaft, then she swallowed his helmet, sealing him with her lips. Her warm spit coated him and he was in heaven. Or possibly hell. The metal man couldn’t decide, or didn’t want to. He watched the girl he trained take more and more of his thick cock, getting a third of the way down before needing to shoot back.

She gagged, coughed slightly, every feeling felt by his sensitive shaft and making him groan. She took a breath and went back at it, the work ethic Colossus had instilled in her paying off. She took more of him, sucked him for longer, growing used to the size of him and the feeling of him filling her mouth. Negasonic teenage head was the best thing ever, Colossus realised. She spat him out, drool hanging off her chin, the look she was giving him determined. “Fuck my mouth,” she said, then enveloped his cock again.

“Blyad…” he grunted as he hit the top of her throat, or rather she hit the head of his cock with the top of her throat. She held herself there, unable to go further without help. Slowly, Colossus withdrew a little of himself, savouring the feeling of her dripping spit continuously running down his shaft. Then he, very carefully and gradually, thrust into her mouth. She moaned around his cock as he filled her almost to the tonsils, then pulled back again.

“There you go,” said Yukio encouragingly, to both Colossus and Negasonic. “Use her mouth.”

This made the hero’s eyes dart to the cheerleader who smiled up at him. “She wants you to,” she explained. “Look at her.” His gaze was redirected to the girl with his cock in her mouth, whose eyes were watery but blazing with lust. “She needs you to.” There was a moan again as he thrust and met a gentle resistance. Ellie’s hands gripped onto his iron thighs, fingers caressing him. “Go for it. You’re not taking advantage of us here,” Yukio said, seemingly trying to assuage her teacher’s fears. “We want this… she wants this…” There was a nod of assent from the Warhead, his cock now passing into her throat. God it felt amazing. He moved his hips again, thick spit dribbling down Ellie’s chin and Piotr’s balls. Now Yukio’s hands were on them, massaging them, and they made a very low pitched ringing sound as she moved them in her palm.

“Ohh...d-damn,” the stoic hero cried out, thrusting again into his student’s skull. She didn’t let up and met his next thrust with her neck. He started going faster, finding her limits easier to pass each time. She was usually a natural, this one. There were many things Colossus had taught her that she had picked up quickly. Now she quickly learned the differing thicknesses along the length of his cock and how it curved as she deep throated it. It was a wonderful feeling being stuffed like this, by her teacher. To taste him down to the throat, smell the metal and feel his stretch. She was so fucking wet. “Girls... “ moaned Colossus, looking down at the two beautiful angels worshiping his metal and getting even harder. “I’m… I’m going to… Bozhe Moi… girls…s-stop...” his voice was straining. His nuts were straining. He held on for dear life, suddenly nearing his end but not wanting it to happen.

Ellie pulled her head away, gasping for air, her cheeks red from the effort, eyes wide with excitement. Yukio was quick with the transfer, immediately stroking the length of him, fast, the slick saliva helping immensely.

“Cum for us… cum for us!” she cheered happily, moving into position with her face. She put her cheek right next to Negasonic’s, the girl catching on quickly and copying Yukio’s opened mouth, tongue out expression.

“Ahh...gnn...I … can’t…” groaned Colossus, gritting his teeth, looking down at the two angelic faces, one streaked with running mascara down and around her cheeks.

“Let me taste it,” Ellie pleaded. “Please… I want it…”
