She broke off the kiss and giggled as she squeezed my hard cock through my shorts. "That was to make sure you miss me while you're gone," she said as she sent me on my way.
I walked to the men's room with a prominent bulge in my shorts, thanks to Mandy's teasing, and then unzipped my pants and pulled out my semi-erect dick to pee at the urinal, as another guy entered and stepped beside me to use the other. I kept my eyes forward, as I always do in a public restroom, and I was startled when the guy beside me spoke.
"Very nice," he said looking down at my still semi-hard dick.
I looked at his face, careful not to look down, and he smiled as his eyes directed me downward. I followed his eyes down to see that his cock was fully hard and I was shocked. Not just because it was hard, but also because it was enormous, easily ten inches long with a thick bulbous head. His hand pumped it slowly as I watched.
Despite the fact that I had never entertained a conscious homosexual thought in my life, I felt my dick twitch and start to stiffen. He continued to slowly stroke his giant cock as he spoke softly. "Do you want a taste?" he asked.
"I don't think so," I stammered as I stuffed my near rigid dick into my pants and walked to the sink. I quickly washed my hands and walked back to Mandy in a daze.
"Did you miss me?" she asked as she pulled me to her and kissed me again. "Mmm, I guess you did," she giggled as she felt my hard cock press against her thigh. "Unless some guy got you hard in the men's room," she teased.
"Actually, some guy did just hit on me in the washroom."
"Oh really? Do tell!"
I proceeded to tell her the whole story, including my unexpected interest in watching him play with his giant cock, and when I finished Mandy was flushed with excitement.
"That was so fucking hot," she said breathlessly. "Feel this," she said softly as she took my hand and guided it under her skirt to her naked pussy. She was soaking wet. "So his dick was really big?" she asked tentatively.
"It was huge, Mandy. Like porn star big."
"Mmm, and looking at him stroking it kind of excited you, didn't it?" Mandy asked. Her voice was thick and raspy and it was clear that she was getting more and more excited.
