"Now start stroking even faster looking at these fully exposed breasts....let me push them together to give you a better view..."
Your balls start to tense from the fast stroking and you're about ready to burst...
Then she says "now stop...no cumming yet...women like me like to watch a man masturbate a long time...Now you don't want to ruin it do you?"
You shake your head no....
"Good now start stroking slowly again"
