I had vowed never again, yet here I am passionately sucking his cock. He watches, eyes bright, lips curled in a tight smile. I work feverishly, craving his spend. Don't tease me! First the sweet precum, but I crave that heavenly honey. Now he's twitching, it's here! Throbbing, his essence flows, thick, hot, copious. Gulping frantically, such luxurious taste! I shudder in ecstasy. Afterwards, he pats my head, turns and leaves. I remain, head down, face burning in embarrassment. He's my son. And I love him. But I vow, never again.
