You see your brother walking towards you, his eyes widening in surprise as he takes in the sight of... himself. "What's going on? Did we swap bodies?" he asks, clearly just as confused as you are. You blush, feeling self-conscious about being in your sister's body and noticing how good it actually feels to be seen this way.

Your brother nods in agreement, still looking you up and down. "I don't understand... how did that happen?" He bites his lip nervously, clearly not sure what to do now that they're stuck in each other's bodies. You can tell he's struggling with the same feelings of confusion and arousal that you are. Maybe there's a way for all three of you to enjoy this situation...
