Ari cried out, his eyes closed, body jerking backward. I caught those slender hips so he wouldn’t fall off my thighs. His eyes flew open, and he watched me, riding the waves of his climax. Ropes of cum shot onto my shirt, staining more than just the fabric. Staining the relationship I thought we had. But after this, how could I go back to pretending he was just the son of my ex-wife? That he hadn’t ridden my lap and begged me to watch him get off?

He collapsed against me, his face pressed to my neck while he gulped air into his lungs. A giggle escaped him, then a sigh. “That was so good. Now it’s your turn. I want to play with you, Daddy.”

What the hell just happened? And what was he doing? Ari slid off my lap, dropped his diaper to the floor, wedged himself between my knees, and yanked down the front of my sweatpants. The waistband was already loose enough that my cock sprang free, unencumbered. And proudly reporting for duty.

He didn’t seem to mind being bare-assed before me as he played with my cock.

Ari glanced up at me with the naughtiest smile. He licked his lips, and my cock twitched.

“This is going to be so much fun.” He caught my cock in his mouth.

Holy shit, Ari’s—mouth—was—on—my—cock. Anne’s I-told-you-so smirk flashed before me, and I pulled away when he released me. I jerked to my feet so quickly I knocked him over. I would have offered him a hand, but I couldn’t. I needed space. Needed some time to think. I did the only thing that still made sense.

I bolted.
