This story is pure fantasy. In real life we should never be cruel or disrespectful towards anyone, especially if they are vulnerable in any way. Loving, consensual sex is wonderful. Coercive, non-consensual or incestuous sex are illegal and extremely harmful. It shouldn't be so, but reading about such things can be erotic. That isn't to condone them or to encourage anyone to act in a similar fashion. We all have fertile imaginations and there is no harm in giving rein to them, so long we never cross the line from fantasy to reality. The characters in my stories are all over 18 and the settings are purely fictional. Mothers, wives, partners, girlfriends, daughters etc. - females in general - must always be treated with respect and kindness.
