Offer him your ass instead.

"No it's that time of the month." You lie. "But you could fuck my ass if you want." As you add this last part you put your leg on the countertop lockin your heel aginst the edge giving as slutty of an invitation as you can muster.

"Now how could I say no to that." He is on you in a second using hand soap to lube your ass, you help using your fingers to pull yourself as wide as possible so he won't rip you in half. "You sure are a nasty slut." He adds as he presses his head aginst your asshole. Then he pushes the head in slowly at first but once the tip is in he procedes to stuff and stuff till his nuts brush your thighs.

"Oh, you are gigantic. Hell I can't take it. You have to stop you are going to tear me in half." You protest moaning and screaming. But as he begins to bang your legs aginst the countertop these soon change. "Oh yeah, ungh ungh, fuck me harder. You are amazing. Fuck yes. Don't stop. Oh fuck yeah ungh."

Finally he drives himself all the way in and holds for a couple of seconds and you know he is going to blow. You thrust back to meet him and then pull forward and out. "Gimme that." You demand and take him deep in your throat, deeper than you would have ever dreamed you were capable, and he blows in your mouth again, his cum spurting out your cheeks with each blast. He holds your hair and pulls you to him as you drain his seed. Finally now going limp he pulls out with a wet slapping noise as you were still sucking, and he pulls up his pants and walks out.

Pausing at the door to look back he states. "If you want some more look me up before you leave." He then leaves. You take a few moments to clean up, redress, put on some more lipstick, and then rejoin the party. After a couple of more hours they announce the final results are going to be given in 5 minutes. You are pleased to hear as they read the names that you are to go on stage as one of the top 5 finalists.
