"Actually I've had a better idea. I'm feeling so horny that I think I'll give you a blow job. Would you like me to suck your dick? Would you like me deep throat your cock, gag on your cock and then let you cum in my mouth?"
"If you really want that, then I need your knob to taste fresh so go and get some toothpaste and rub it all over your cock. All the way around and all the way along the shaft."
