In this passage from "The Host" by Stephenie Meyer, the protagonist experiences a powerful and intense physical response to another person. The sensation of their skin touching creates a burning feeling that is both pleasurable and deeply emotional. This indicates a strong connection between the characters, suggesting that their interactions evoke strong feelings beyond mere physical attraction.

The mention of an "aching in my chest" implies that this connection is not just surface-level; it taps into deeper feelings of longing and vulnerability. The blend of pleasure with this emotional ache highlights the complexity of relationships and the profound impact that personal connections can have on one’s heart and mind.
