You quickly possess your sister

You quickly pounce upon your sister, your new amulet glowing as she struggles beneath you, having knocked her to the floor. Her amulet glows in resonance with your own as you feel a surge in power. Your hands clamp down onto hers as they sink into her. She struggles, kicking her legs, screaming as you quickly kiss her to muffle her cries for help as the world fades away...

Soon, you awaken, eyes wide, your new body drenched in sweat as her amulet... No, YOUR amulet now... Glows even more brightly, the lamb's power added to its own. You can feel your sister struggling beneath you, but its far too late...You had two of the amulets now, and you could feel your own powers grow... You knew she could do nothing to stop you now... But was this power too much for either of you? What would happen if you exited her body... Would she get the new upgraded amulet or you...? Should you destroy it... Or keep this power for yourself.
