Casper's POV

Rex glanced down at my erection before meeting my gaze again. "I'm hard too, really hard, but I figured you might not want to take it any further," he said. 

I bit my lip, tightening my arms around his neck while my hips pressed against him. "I don’t want to stop here. We don’t need to have sex right now, but… we can do other things," I whispered. 

His hands slid beneath my shirt, exploring my body. "Casper, I'm going to touch you all over," he said, pinching my nipples. 

"O-okay," I responded, shivering slightly. 

He removed my shirt and tossed it aside, his mouth moving to my neck. This time, he bit down and then licked the spot he had just bitten. I moaned, gripping his shirt tightly. He kissed me again, his hands still teasing my nipples, sending more moans into the kiss. 

I lifted his shirt, signaling that I wanted it off, and he complied. He continued to kiss my neck while his hands played with my nipples. 

Suddenly, he lifted me, wrapping my legs around his waist as we kept kissing. He began to walk backward, our lips still locked. He set me down on my feet with my back against the wall, squeezing my ass firmly. I pulled back from the kiss, letting out a deep moan. 

"Do you realize how incredibly sexy you are?" he whispered in my ear, kissing my jawline. 

My pants felt extremely tight, and I could tell my briefs were damp from the pre-cum that had leaked. Still leaning against the wall, he grinded against me, making our hard erections press together. 

"Rex-" I felt my dick twitch, feeling all kinds of sensations coursing through me. He pulled down my pants, bringing out my dick and slowly pumping it. My moans became louder as he increased the pace. He suddenly slowed down before whispering in my ears, "wanna frot with me?"

I didn't have time to respond before he stopped bringing out his own hard dick and placing it with mine. He pushed into me, moving up and down, creating motion as our hard wet dicks rubbed together. 

I held his arms so tightly I thought my nails would break into his skin. I felt so good that I didn't care if I was moaning loudly. It all felt so good that I didn't want him to stop.

"I've dreamt about doing this with you a few times. I have wet dreams about you Casper." He said, gripping my ass as he pushed me into him more, continuing the up and down movement. 

It was all so much that I knew I would cum any moment from now. "R-rex....I-I'm...hmn....c-close." I managed to say in between moans. 

He groaned, increasing the pace, squeezing my hard extra hard. I struggled to keep up with his pace and my legs were getting weak. "Rex....mmn....fuck." I said as I came.

He came after me, biting into my neck as if trying to suppress his sounds. 

After coming down from our high, I collapsed into him, breathing heavily. He hugged me, ruffling my hair as he chuckled, "let's go shower." 

I just nodded against his shoulders. He chuckled again before lifting me up and taking me to his bathroom.
