With his powers (option 1)

"If you don't stop, I'm telling dad!"

Matt smirked at his twin sister for a moment, then flexed his mind, jumping into his dad's mind. With a start, he realized the body he was in was currently grinding against its wife's ass, pressing her hips against the kitchen counter.

"Nate, what if the kids come downstairs?" Matt heard his mom moan, her hand going to his as he pressed his fingers against her pussy.

"I'm sure they won't be down for a while," Matt purred in his dad's voice, "but if it makes you feel better, I'll go up and check on them."

He left Helen at the countertop, pinching her ass as he turned, and walked through the door to get to the stairs. He climbed silently, and for more than not wanting Lily and his own body to hear. He wanted to make sure his mom "knew" her kids wouldn't interfere. After all, if his dad wanted to fuck his own wife, who was Matt to deny him that? Especially when Nate could get hard this soon after fucking his own teenage daughter?

Matt stood at the bedroom door for a moment, peering in. Apparently when he jumed out of his body, his body decided what it would or wouldn't do, and he watched as his body reached out and grabbed Lily's ankles, dragging her to the edge of the bed, her legs spread around his hips.

"What's going on in here," Matt demanded, opening the door and stepping in, making sure to be quiet enough so his voice didn't carry downstairs.

"Daddy, help," Lily gasped, looking past Matt's body. "He... he's trying to **** me!"

Matt's body turned its head, and suddenly Matt felt a sttrange buzzing, almost like minor feedback, whine through Nate's brain. Then he felt the jealousy surge in his dad's mind, and quickly squashed it, adjusting the natural flow of thoughts in the brain he currently occupied. "Well, if you don't want him to **** you," Matt said, looking directly into Lily's eyes, "stop fighting. Matt, keep her busy for a little bit while I go and fuck your mother."

Matt's body nodded, turning back to look at Lily, who now lay there with a stunned expression on her face. Matt turned around and walked out of the bedroom, closing the door silently behind him before jumping back into his own body.

"It doesn't look like telling dad would do much good, does it?" he asked, licking his lips. He pulled her closer to the edge, until his cock head bumped against the hand she still held against her pussy. "you heard him. If you don't want to be ****, stop fighting." He used one hand to move hers, then pressed his hips forward, his cock head pressing between her labia.

"Daddy," she whispered, still not looking at him, looking toward the door that Nate had just vacated. Using the hand he had just moved Lily's hand with, Matt steadied his cock pressing forward, watching as his virginal cock penetrated his twin sister's cum filled pussy.

Lily hissed as he thrust, finally looking up at him as he sunk deep into her body. He moved his hands, off his cock and her leg, sliding them both up Lily's smooth stomach to cup over her modest breasts, her nipples tiny pebbles between his clenching fingers. She hissed again, and Matt pulled most of the way out of her pussy before thrusting inside her again.

Again and again he pounded into her, rocking her naked body back and forth on her bed, hands squeezing the mounds of her breasts without a care to the pain he caused. His cock had never experienced this intensity of pleasure before, not even close, and he wanted to make the experience last, but his own inexperience betrayed him. With one final, exuberant thrust, he buried his cock deep inside Lily, arching his back as it started spasming, adding his cum to the load their dad had already pumped into her.

Matt collapsed onto her, his mouth seeking out her left breast and sucking her nipple in, his cock still buried inside Lily. God, he felt great - better than he had ever felt, and he hoped he would be able to feel this way regularly. Then curiosity struck, and he jumped into his dad's mind again. Yup, they were busy at it, apparently neither of them caring that Nate's cock had still been slick with his daughter's juices when he slid inside Helen's pussy.

He jumped back, his mouth now on Lily's other breast, his tongue swirling around her nipple. Matt realized this new power was going to be a lot more fun than he had originally thought.
