Then she has you sit in the tub to be washed, saying in a warm, mothering tone:
"Let me see if I can help get all those excess sperm out before you go to the beach and see all those beautiful girls!"
You know it's probably a trick, but you want to believe it.
And it feels so good as she soaps you up and starts to pull the pre-cum up through your cock.
You feel your orgasm building, and try for the release you want so much.
And she seems to be doing everything just right to help you have a good, satisfying cum.
