"I asked "Really?" and Mommy just nodded so I pulled my cock out and walked up to her and she just got to her knees. I was half expecting her to say "Just kidding!" but I rubbed my teen cock all over her face before I finally slipped it into her mouth.
I started out slow and gentle and didn't even try to go all the way in. When I was close to cumming, I warned her and asked if I should pull out but she just reached up and gave my balls a gentle squeeze so I filled her mouth with the biggest load I'd ever shot. And then I... I kept going.
I wasn't as gentle the second time but still didn't try for her throat and I only warned her about my second load and didn't ask because I knew she wanted it. I finally stopped after the seventh load. By that point I'd been grabbing her head and jamming my whole cock into her slutty mommy mouth, holding her down for long stretches, all while we'd stared into each other's eyes.
Her makeup was beyond ruined and a mixture of drool and cum had run down her chin and dripped onto her fat tits. She was so fucking beautiful. I pulled her up and kissed her messy mouth and told her she was the best mommy in the world. And that was how it started."
