When the costume feels a tongue licking across “it’s” pussy, it turns its head back to find a black labrador licking at her rear, without thinking and acting on instinct, the “female” lifts her tail, and the male, which is “Lennon”, takes the hint and immediately jumps onto the “female’s” back, instantly beginning to thrust his hips, both letting out howls when the “male’s” cock penetrates the “female’s” pussy, the male simply continuing with his thrusting.
Lennon finds himself wrapping his front legs around the female’s waist, not seeming to care at how weird and wrong this dream feels, simply listening to his “mind” which tells him to just do what he feels is right, and to Lennon: mating a female dog feels like the right thing to do.
Henry himself feels a huge pleasure rush through his body as the male “dog” rams his cock into him, the boy, like Lennon, not caring about how wrong this dream feels, simply believing that this is what has to happen. Both boys oblivious to what they are doing, as their minds and actions are fully under the costumes influences, currently Henry and Lennon don’t see each other as friends, for Lennon, Henry is just some stray bitch in heat, and for Henry, Lennon is some stray male mating HER, exactly how nature wants it to be.
Soon both “dogs” howl in triumph as they cum together, Lennon shooting his very first load ever deep into the “bitch”, his friend, beneath him, filling Henry’s womb and impregnating him. What both boys are unaware of, is that the costumes have used their magic to alter their DNA from human to dog in order for the “female” to be able to get pregnant by a real male dog and for the “male” to be able to impregnate a real female dog.
Lennon pulls out of Henry, before simply beginning to lick himself clean, while Henry does the same, once done, the two “dogs” simply join the rest of the pack in their games.
