"You're serious," said Karen. "You actually did this. You jerked off in a stall, in the men's locker room, at the gym?"
"Yeah," I replied. " I did."
"Why?" she asked. "Weren't you afraid of getting caught?"
"Of course. But I was careful. And quiet."
I had just told Karen about a repeating fantasy I had had about her. We had been together for several months now. I was feeling very comfortable with her and had wanted to tell her about an incident that had occurred many months ago, before we first got together.
"Couldn't you wait until you got home, at least?" she asked.
"I told you, I had to get to the office. I needed to shower first, and it just wouldn't go down. I didn't want to walk around with a full erection."
"I guess it would be kind of difficult to hide that big thing," she said, taking my cock in her hand and stroking it. It was true. It was big; very big, by some standards.
She had measured it a few weeks previously, just for fun, though I already knew what size it was. She had been very turned on by the whole measuring thing. "Wow," she had commented, "over 8 and Β½ inches long and almost 6 inches around. No wonder it hurt the first couple of times." She had jokingly referred to me as "Big Dick" for the next few days.
"And this was all because of a fantasy about you and me?" she asked.
"Yeah. I told you that I had had a hard on for you since the first time I saw you. I was headed to the locker room that day when I noticed you, bent over the bench, doing a set of one handed rowing. You looked exactly like the fantasy I had enjoyed the night before. Seeing you and remembering the fantasy trigged my response. I sat in the lounge and flipped through a magazine for ten minutes, waiting for things to die down, but it was still hard and I had to get going."
The truth was, this hadn't been a solitary incident. Being around Karen, lusting after Karen, constantly fantasizing about her had made for a lot of very horny moments. Many times I had needed to take matters into my own hands. But I wasn't ready to confess everything to her. Not yet, anyway.
"Did it do the trick?" she teased.
