Summary: Superior Iron Man has a new line of toys to test out and see how well they work with his VR tech and he's getting MCU!Peter to help.

Tony dropped onto the couch and pulled Peter into his lap. "Now, do you really want to see what I can make this toy do?" he asked with a soft pat to Peter's ass. He had spent several minutes prior prepping Peter and pushing his new prototype tentacle-shaped toy into the lovely sub-in-training on his lap. "I think you'll like it," he added as a single, thin tendril of the endosym armor slid along Peter's thigh.

Peter nodded. "If you're serious about that, yes. Absolutely." He reached a hand down to pass his fingers over the bit of the armor. "Yes, please." Peter was nearly vibrating on his own.

"Guess it's good I built my toys to integrate with my armor, huh?" The armor in question snaked around, over Peter's hip, to slide between his cheeks until it melded with the toy resting there. "First, we have it warm up a little," he said. Peter's hips jumped. "Then it will start to move. Little undulating waves."

Peter moaned softly, warm and deep. Clearly he was enjoying the slow movement and comfortable warmth of the toy as it wiggled inside him. "It – it almost feels like it's trying to go deeper," he said.

"Maybe it is." Tony leaned forward to press a soft kiss to Peter's mouth. Gently, he settled the sleek Stark VR headset onto Peter's face. Then put on his own. "Now, we're in the ocean. And you – the brave sailor – have fallen from your damaged ship. At first you were afraid the large tentacled creature was going to hurt you. But, instead, it's dragged you to its cave. Now the tentacles are exploring your skin. Has this creature seen humans before? Perhaps. Either way, it is very interested in exploring your gaping mouth and your tight asshole." Tony let more of his armor wander out in exploration.

Peter hummed softly. His hips rolled gently in time with the movement of the tentacle toy in his ass.

"It's reaching deeper insider you. It's exploring. Maybe trying to learn. Or maybe it is doing exactly what you think and treating you like its personal sex toy," Tony continued. "Are you wanting to swim away?"

Peter shook his head, fingers gripping tight to Tony's shoulders. He tried to say 'no', but it was muffled by the tendril of endosym filling his mouth. His hips rocked forward. A clear indication he was still on board.

"Good. Because the creature isn't done with you yet. The warm, narrow tip of the tentacle reaches further, pushing even deeper. It starts to writhe around inside you like it's looking for something."

He felt Peter's body shift again. And he heard the muffled moan when the wily tentacle found its mark.

"Good boy, let the creature take you. Let it have you. It seems to only want good things for you. Let it take what it wants." Tony smiled to himself as Peter moaned again, rocking his hips like he was seeking friction against his hard, neglected cock. That was the one thing Tony wasn't giving him this time, but he knew it would work out in the end.

Peter let out a slow frustrated little sound.

"Oh, don't worry. The sea creature wants to make sure your time beneath the water is special. It's going to take good care of you. Now, be very good and suck on that tentacle in your mouth. Show your gracious under sea host how well you can do it." The armor kept its tentacle shape as it slowly fucked into Peter's mouth. The armor controlling the tentacle-shaped toy in Peter's ass kept up the writhing and wriggling, occasionally brushing Peter's prostate with its movements.

"Do you want the creature to fuck you, Peter?" Tony asked. In response, he received an affirmative whine.

Slowly the armor altered its movements. Starting to pull out of Peter, only to slither back in again.

"The creature realizes what you really want and starts to fuck your perfect ass." As Tony speaks, the VR scene follows his narrative, images flowing and shifting to match the story. "Drawing slowly back to almost completely leave your body, then reversing and pressing back in again. Pumping slow and steady. It's waiting, Peter. Waiting for you to ride it. To show it some appreciation. Show it that you enjoy what it's doing for you. Maybe, if you're very very good, it'll fill you up with its sticky sea creature come. Your mouth and your ass. You'll be covered in it. Wanting more."

Peter groaned – another sound muffled by the armor-tentacle filling his mouth.

Inside the VR simulation, Peter was fucking beautiful – same as in the real world. He was kneeling on a flat rock with the large tentacle creature spread out around him. One tentacle slowly fucking his mouth and another seeing how deep into his ass it could stuff itself on each inward thrust. The remaining tentacles waved about around them. Every now and then, one or two would dance patterns across Peter's skin. But non of them every touched Peter's very hard, very needy cock.

Peter whined again. Tony knew that sound. It was Peter's 'I really really need to come now' sound. But Tony also knew Peter could hold out a while longer before he exploded.

"The creature makes a soothing sound that seems to say 'not yet' even as it continues to use your beautiful body. It fucks you and fucks you. Urging you to fuck it back. Pushing you through that resistance to move. Pushing you to work across that burning for orgasm. It won't leave you unsatisfied. You just need to hold on a bit longer."

Tony knew it wouldn't take long before Peter lost the orgasm battle. In fact, it only took a couple more little thrusts of the tentacle toy into his ass before he spilled all over himself – both in the VR simulation and back in actual reality.

"Oh, very good, Peter. Now the creature has something for you. First, the one wriggles deeper into your ass before spilling its sticky sea creature come deep inside you. Next, the one in your mouth pushes in almost enough to make you gag before it gushes sea creature come deep in your throat." Even watching that in VR was delicious. Tony only did wish it was his actual cock and not just his armor.

Peter moaned and swallowed. Tony had told him before they'd gotten started that the come substance was a food-grade organic compound and not actual come. So it wouldn't hurt him to eat it – though the taste might be less than pleasant.

In the VR sim, Peter folded to the sea floor once he was done. In reality, Peter fell forward against Tony's chest. His eyes closed and his breaths heavy.

Tony slid his arms around the young man, whispering softly to him. Once Peter had come down enough, Tony turned off the VR and set the state-of-the-art headsets aside.

"You did so well, Pete." He kissed the top of Peter's head. The whole scene had been incredible. This VR set-up would be excellent for when Peter was back up at MIT.

"That was awesome," Peter muttered into Tony's chest. "But, ohmygod I need a bath."

Coming right up.
