He warns you

"Oh, that's good," Mr. Crassle murmurs as your lips drag up and down the shaft of his swollen prick. "Just like that."

You twist your wrist each time you slide your hand down to his balls. Your slurping mouth chases it down, impaling your mouth on his prick. You can feel it swelling up and you can taste a salty hint of his precum.

"I'm almost there," he pants, his hips thrusting against your fist as he urgently tries to fuck your mouth.

"Mmmmm," you reply, glad he's living up to his end of the deal.

You pick up the pace, your hand and head moving rapidly to bring the older man to his orgasm. After a few more seconds his grip on your head tightens.

"Ohhhh," he groans, "gonna cum."

You pull your mouth from his cock with a slurp. Your hand continues to stroke his wet shaft, but you aim his cock at the metal partition of the stall. You watch as his cock turns a deep purple in your hand. His head swells and then, with a cry from the older man, his cock twitches and starts spewing thick ropes of yellowish sperm. Mr. Crassle pumps his load out against the blue stall divider as you stroke the cum from his churning balls. The last few squirts ooze out and drip from his cock onto the tile floor.

"Thanks, babe," Mr. Crassle says, releasing his grip on your head. "You're a hell of a cocksucker."

Mr. Crassle tucks his softening prick back into his boxers and zips up. You wipe your hand and lips clean with some toilet paper and give the toilet another flush.

Crassle gives your butt a swat and walks out of the stall. An elderly woman doing her makeup yelps at the sight of the old man. He gives her a shooter and walks out whistling.

With a sigh, you walk out of the stall and wash up your face. You take a moment to reapply your lipstick before you return to the table. Mr. Crassle is already back at the table, tucking into his steak while his ditzy wife picks at a salad. You feel bad about what just happened, but you remember what Mr. Wood said about allowing boyfriends. All the same, you doubt he'd like to hear you just sucked off his worst enemy, so you have trouble making eye contact with him when he welcomes you back to the table.

All the same, as you settle into your chair you pat him affectionately on the leg.
