Before you even have a chance to even process, your new powers. A swap already happens, and not one you wanted. Jacob, your 18 month old Border Collie, blissfully unaware of your ability skips towards you, excitedly rubbing against you. "No, boy! Not now!" But, it's too late. You feel your head detach from your body with a loud pop sound. Seeing Jacob doing the same, whimpering in panic while his body was perfectly still waiting for its new head, your body just as motionless.
Slowly but surely, your head drifted downwards. Hearing a 'click' as it connected to his body. Feeling his fur brushing against your neck, you awkwardly tried and failed to walk on your new four limbs. Meanwhile, Jacob's head became attached to your body. Curiosity got the better of him, groping his chest and stomach. "Hey, stop it. That's my body." He paused and looked down, trying to stand up. Only to stumble on his new body, catching himself before hitting the pavement. Inadvertently hitting you in the face, with your old breasts. Sitting back up, Jacob gave you a confused look, whimpering oddly at their situation. "I'm sorry about this Jacob. Hey can you understand me?"
His ears perked up, and he barked excitedly licking her. "That's great! we're gonna figure this out okay?" He nodded and after a moment, he managed to stand up. Readjusting his top to conceal his cleavage. It made you happy to know your pet didn't instantly prev out on your body enough to wag your tail subconsciously. "Here's the plan. Just head out, hope no one sees us like this and get our bodies back." He barked in agreement and you hopped on the street.
