Does Verizon show your call history on the bill?

So I've been calling my girlfriend at 2 am every night and we stay up till like 7 sometimes. My sister pays my bill she's an employee at Verizon, will my calls all show up there on my bill? Also can she listen to my calls if she wanted? Will my calls show the date time and duration I'm a bit neverous we kinda had a dirty talk last night and I think my sister may have access to listen to my past calls! Help? How can I prevent my calls from showing up on my bill I have a iPhone 5s

Yes, Verizon shows a detailed bill of every incoming and outgoing call, the duration of the call and time of day it was. Listening in on calls can't be done

You can prevent calls from showing up on the bill if you use FaceTime or Skype over Wi-Fi.
Make sure you are both using area codes covered by your long distance plan. My sons girlfriend got a Canadian area code by mistake.
