CW: There is a mention of manhandling/spanks but it doesn't happen in real time. I have used the rape tag because the woman is reluctant when Sir initiates sex during aftercare. It is gentle and pleasurable for both, but she does ask to wait until the next day more than once. Be aware of that if it's not your thing. The basic premise is that Sir surprises his sub with an unknown number of men who are there to give her pleasure.
