I interrupted them anyway."What is this, Lorraine?"She looked over the letter. "Oh. Good! They could use you up here. I would have asked you, but I th...ught you were retiring." I am retired. Past tense. I'm an old man; I no longer have to work for a living." Boss, we're almost done here." Ivan sighed like I was the problem. "Can we finish this then you yell at the bride."I glared at him, but I took his point. "I'll be in my office. Call me when you're done."I did leave the dining room, intent to.

From a gentle easing backwards she’s now beginning to shove her ass down on my cock, finally getting the fucking she wanted from the boy earlier that night. “May I Daddy? May I cum please Daddy?”.
