Currently on holiday for DBro's 30th with me, DH, DSis, her DW, DBro, his DW, our DMum and DDad and combined 7 kids. Distant holiday, excuse late night post - we're a military family (me, DSis and DBro) and were unable to make dates for this family trip during half term). About 40 mins ago went back to room for shower and DBro asked me to grab his phone, which was charging, on my way back. When I took the phone off charge the screen illuminated automatically and I saw a message from a name I didn't recognise which seemed to me to be clearly a reply to a dick pic. Verbatim "your dick looks great from all angles, that's what I remember...[message preview cut off]". I couldn't believe what I'd seen so clicked to lock the phone. Clicked again to see what percentage of charge and it had a passcode so saw no more than that message preview. Honestly don't know what to do. Did not mean to pry but have now seen this. Three more days of potentially awkward holiday remaining.
