On her pussy

Pulling out, you rapidly stroke your cock, knowing you're seconds away from cumming. You feel the familiar tension build in your balls, move through your shaft, up to the head, then explode out, coating her well-fucked pussy with your cum. Your abdomen contracts, pushing out wave after wave of cum onto her labia, bush, and stomach, as Mrs. Carter looks on with glee.

As the last of your cum drips from your tip, you wipe it off on her inner thigh. Once finished, you slip off the massage table, leaving her trembling and covered in your cream, and make your way to the sink to get yourself washed up. "I hope that helped with the new spot you were telling me about today." you say, slipping back into professional mode. You think about an extra $100 in your pocket every week and realize that wasn't the worst thing you've ever done in your life. Toweling yourself off, you make your way back towards her. "Perhaps we can reassess that at next week's appointment and decide if more work is needed?"

Mrs. Carter actually smiles at you, eyes still half-closed in orgasmic glory while playing with the puddle of cum you left on her. "Well, I have to say that this is the best I've ever felt after a massage. I can't remember the last time someone got to those spots and I think we'll have to spend a lot of time on that for now on. I only wish we had found it sooner."

Mrs. Carter waddles over to her purse and counts out $300. "I think you and I both know you went above and beyond what was agreed upon. I appreciate the initiative you took." she says, handing it to you. "Worth every penny." she whispers in your ear. You quickly gather your clothes to get dressed, pocket the money, then excuse yourself from the room and let Mrs. Carter get herself changed.
