Cassie Pt. 4

—-

About a week had gone by since Cassie and I talked. She was so busy with work and school, and me with kicking my schedule up to full-time now that I was out of high school. I only saw mom once and that was just before heading out to work.

Friday night had rolled around and my buddies were begging me to go out with them, but I really didn’t feel like getting drunk. Instead, I caught up on some sleep. In the morning, I felt extremely refreshed. Actually it was the most refreshed I’d felt in a very long time. With a jump in my step, I stretched briefly before throwing on some sweat pants. A brisk morning jog sounded really good. Before I left the house, I noticed Cassie running around the house frantically. She must’ve woke up late.

I paused near the door and stared at her keys. Dare I even tempt fate? Yes, yes I totally should.

She reached out to grab her keys from the table but I snatched them just in time. She halted, a bit confused, then immediately her temper flared.

“Hey! Not funny, dick!” She growled and immediately tried to grab them.

I chuckled and held them behind my back. “Slow down, assie. Where’s mom?”

“She’s not here, and I’m going to be late for class!” She punched my arm, not with all her strength, but it still kinda hurt regardless.

“Hey! Isn’t that like, domestic abuse?” I joked as she tried to reach around me to get her keys. She rolled her eyes and just looked at me as if she were about to call me an idiot. I took the opportunity to quickly lean down and kiss her. I actually kinda missed her lips and ended up kissing near the corner of her mouth, but she readjusted herself so that she was kissing back properly. But what I intended to be sweet and innocent quickly turned hot and passionate. It was a deep and needy kiss, the kinda kiss you give someone right before you fuck them relentlessly, the kinda kiss you don’t just give and then part ways. Her tongue probed mine lightly. Hands were beginning to roam: I grabbed her breasts and she hastily reached into my sweat pants to stroke my cock roughly. I humped her hand and tried to find her nipples with my thumbs, but it was too hard over her thick bra.

Suddenly she broke contact.

“You have 5 minutes to cum, knob.” She said breathlessly and dropped to her knees. Before I could even protest (after all, I actually really didn’t want her to miss her class), she whipped my dick out and slurped it whole, only momentarily, before pumping my dick rapidly as if her life depended on it. I lurched forward as she practically assaulted my dick with her hands and mouth, her sole purpose to make me cum. I breathed heavily as she took it in her mouth again whole, swallowing it only momentarily before bobbing on it rapidly. It was a staggering contrast to her previous blowjob: she was rough and quick, only wanting me to climax and not necessarily care how I got there. That was fine with me. Although I did enjoy the slower and more powerful build-up that made the climax more intense, right now the release was all that mattered.

“Fuck!” I cried before lurching forward once more to empty the contents of my nuts in her mouth. A small part of me reminded myself that I was about to fill my sister’s stomach with my seed.

And damned if that didn’t make it SO much more intense.

I jerked forward repeatedly with each wave of cum until settling down. I could hardly catch my breath before she stood up and began undoing her belt buckle.
