Ai and Aki

Ai and Aki are sitting on the couch inside the living room, waiting for their Onii-chan to tell them what he wants from them. You're together with them, gathering your courage to ask your request, stealing glances at their huge breasts every now and then. Despite both being very young, Ai being 12 and Aki being 10, both have gigantic breasts, with Ai having a K-cup and Aki having amazing S-cup-size breasts. You can't help but fantasize about them. Ai:"What's wrong, Onii-chan?" Ai asks, a bit worried. Aki:"What didya want? I bet it's something ecchi." Aki complements Ai, smirking while teasing you.
