Show him

"Get down on the ground." you say, confidently.

"Dude, what?" Teddy asked, following your order.

"I can't just tell you," you say, looking down at Teddy, "I have to show you what happened. Otherwise, you won't believe me. Now take off your shirt."

"This is weird, bro..." he said, pulling off his t-shirt.

"Trust me." you say, admiring your twin brother's physique, even though it matched yours, "Now, CJ was looking under your bed."

"Okay..." Teddy said, cautiously peering underneath his bed. "Now what?"

You chuckled at your twin falling for your trick. You took off the towel, now completely naked in your room. You admired your brother, looking under his bed with his ass poking out. It was arched perfectly and you felt déjà vu staring at him.

"Then I pulled down his pants and plugged his hole with my dick."

You quickly pulled down Teddy's shorts and guided your cock into his tight hole. Teddy jolted in shock, screaming at the intrusion.

"Dude, what the fuck!" he yelled, trying to back out without backing onto your dick, "Why would you fuck our brother! Why would you fuck me! This is sick! Fuck it hurts! Stop it!"

"Teddy, calm down!" you yelled, holding him in place, "I said since he came into our room and was rude to me, it was only fair I got to fuck him. I'm just showing you what I did since you wanted to know. And yes, he reacted the same way when I penetrated him, but I told him to relax and that it felt good. Because it felt so good, that's why he came on the floor."

You could sense Teddy's unsure mind comprehending what you said. Quickly, though, you felt him, and his arse, relax. Taking it as an invitation, you began pushing your member slowly into Teddy, further and further. Teddy moaned as he was continually opened up, feeling the cock press into him. You finally got yourself completely into your brother, and began bottoming out. You could hear your brother groan as your dick began retracting from his love tunnel. Just as quickly, though, you pushed back into him. You began getting into a rhythm of fucking Teddy, gaining pace as you felt more confident he could take it. Teddy, for his part, was moaning nonstop. The sound made you feel like shooting off already. As you continued screwing him, you hit his button, causing Teddy to moan loudly.

"Oh fuck!" he cried as he came, coating the carpet in the same place CJ did.

You felt Teddy's hole spasiming as his orgasm hit him, causing you to go over the edge as well.

"Oh god Teddy!" you groaned, pressing entirely into him, "Take my fucking cum!"

As Teddy's orgasm began to subside, you began to fill your twin with your cream. You moaned loudly as you turned Teddy's asshole white with cum, as your brother lay panting from the fuck. You eventually felt the heavenly sensations pass over, leaving you in a post-fuck daze. You slowly pulled you, seeing a glob of cum escape his hole just as it did with CJ. Teddy finally sat up and glared at you.

"Now I gotta clean this all over again."
