Donnie is just a pony anthro and he's only trying to get home late at night when a futa delight accosts him. Why would a lonely stallion like him, after all, not want to step into her arms when he's struck out?
No... Truly, he's only too keen to let her control wrap itself around his mind, leading him into delicious desires, illicit wants, everything coming to a heated, satisfying head. He needs it and she needs it too, parts of her throbbing up hard and ready, her passion clear to see. And he's not going to deny her even as she changes his mind to suit her will, two souls coming together as she takes all she needs from him.
Thing is, Donnie is a very willing participant even in the submission of his own control...
