Excuse yourself.

Lauren's teasing had become full-blown rubbing by now. She gripped my cock through my pants and stroked it. The situation I was in made me about as aroused as I had ever been and I wanted so bad to let her jerk me to orgasm (and possibly more), but, fortunately or unfortunately, my rational mind took command at that point. If anything happened, it could have been the most embarrassing situation of my life, especially with my kid sister right there sitting across from me. Not to mention everyone else at the restaurant -- we came here fairly regularly and I'm sure we would be blacklisted or at least the waiters would remember what had happened for a long, long time. Did I want to be "the handjob guy" around here?

It pained me to do it, but I lifted her arm out of my lap and placed it back in hers. "That's the end of that," I thought and hoped to have a peaceful dinner. However, I was still extemely stimulated and, in the back of my mind, hoped she continued to play with me under the table.

And she did. In the matter of a few seconds, her hand was back again, rubbing me through my pants, driving me wild. I nearly gave myself away with a groan, but managed to hold it in. No, if I let her keep going, something bad will happen. I know it. I put her hand back in her lap again. Almost immediately it was back in my lap again --- she really couldn't take a hint.

"Excuse me," I said as I pushed away from the table and from Lauren's hand as I got up, attempting to cover the bulge in my pants with my napkin as I turned around and went off to the restroom. I closed the door and breathed a sigh of relief.
