embarrassed start sucking it

Red in shame you don't see any choice but to obey. So, you sit in front of him and grab his cock.
A small shock runs through your body "A slut doesn't sit... you should kneel"
You're about to protest but think it twice and kneel in front of him. Seeing his big cock so close it looks terribly big and you fear not to be able to get it in your mouth
slowly you get it into your mouth and wrap your lips around it as you guess it's to be done
