Leaning/peeking

Hello, recently i've been trying to implement Leaning into my fps game but it doesn't work like i wanted to. My camera is tilting left and right but its just rotation, i want it to move a little to the left/right so i can peek corners. Can anyone help?

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class LeanBehaviour : MonoBehaviour {

 public Transform _Pivot;

 public float speed = 100f;
 public float maxAngle = 20f;

 float curAngle = 0f;

 // Use this for initialization
 void Awake()
 {
     if (_Pivot == null && transform.parent != null) _Pivot = transform.parent;
 }

 // Update is called once per frame
 void Update()
 {

     // lean left
     if (Input.GetKey(KeyCode.Q))
     {
         curAngle = Mathf.MoveTowardsAngle(curAngle, maxAngle, speed * Time.deltaTime);
     }
     // lean right
     else if (Input.GetKey(KeyCode.E))
     {
         curAngle = Mathf.MoveTowardsAngle(curAngle, -maxAngle, speed * Time.deltaTime);
     }
     // reset lean
     else
     {
         curAngle = Mathf.MoveTowardsAngle(curAngle, 0f, speed * Time.deltaTime);
     }

     _Pivot.transform.localRotation = Quaternion.AngleAxis(curAngle, Vector3.forward);
 }

}
