>> A pony's magic is the representation of her very soul
>> When your mare cums inside of you, she quite literally puts her very essence inside of you
>> Turns out, human beings have no magical signature at all
>> So when your mare blows her load inside of you, she more or less automatically hypnotizes you into instantly falling in love with - and being fanatically dedicated to - her
>> Some mares are very wary of the effect they have on humans and worry about the fact that they can more or less mentally enslave humans by fucking them, with all the moral implications that implies
>> Other mares, less ethically burdened.... uh.... are not
>> The matter is further complicated by the fact that being in a mare's thrall feels intensely, blissfully, impossibly good
>> Most, once experiencing it, can't live without, and are much happier overall
>> There is a real argument to be made for futa mares fucking humans 'for their own good'
