Im a bit o f a liar,i offer cim.
But most of time i dont do..but let them think i am!
I have a tecnique of putting my lips over cock,but with lip tight shut,then when they come open my lips but keep teeth clamped together..very rarely come goes straight in my mouth..
Also if theres no getting away with it cus there staring..i only put tongue out,but with lips together again..and i always have a clean towel to hand to wipe straight away..
If they try and get it right in my mouth and come,i say cant go deep incase i swallow,and its risky..
they probably think its not the best..but i dont want rude repeat custom like that anyhow.
So dont care!
