Sorry, no photos 
In defence it was my DS (15), it's been growing for a while now and started to look like it'd disappear. But last night...rubs thighs...just before me and DH went out I had another look.
It was ready.
I squeezed and it exploded over my shoulder. Bliss.
He complained so I took him to the sink and saw that there was more!!! It 'cracked' three times with lovely gunk.
I left him with blood streaming out of it and some antibacterial gel. Had a lovely meal out too 
I'll see how it looks this morning.
