If an MPA loved CIM, she wouldn't charge for it. She would put a poster on a light post and invite the whole neighbourhood over to cum in her mouth 100s of times.
MPAs swallow load because they have bills to pay and addiction to feed, not for the enjoyment. Some MPAs find that CIM gives them a competitive edge. Yes many women learn to love CIM, but for others civies and whores alike it is just money in the bank.
