Huh. Then I realized that I had a raging hard-on. Why? I never got off on wearing women's clothes like those freak transvestites I saw on TV. Bu... I must have been sporting a nine or ten inch erection - bigger than usual - and it showed through that tight, clingy skirt. People were really beginning to stare, so I ran as fast as I could in those damned heels and skirt the rest of the way home. The skirt really was tight. I had to make those same foolish mincing steps I had thought. Jill told them we are going on a fucking vacation in Miami Beach. It was already cold here in Chicago so we were dressed accordingly. Except under Jill’s coat she was wearing a shirt that tied in the front revealing her toned belly and big tits. Her shorts were cut offs showing the roundness of her ass cheeks. We went arm and arm in the airport, no one suspecting we are brother and sister. We were still playing the married couple for everyone. We couldn’t use Jill’s airline discount because. She reached around and undid Sandra's bra. The woman's face was right next to Sandra's. "We're going to be very good friends, chiquita," said the woman as she smiled. Sandra could smell the woman's cheap perfume mixed with liquor and cigarette smoke. Sandra's heavy tits sagged as they were released from her bra. Her hands were again tied behind her back. The woman knelt in front of Sandra and began to pull down her pantihose, exposing the dark brown hair of Sandra's pussy. "Mira, she's not a. . cum. A very large drop of precum, to be exact. And while I enjoyed my first drop of black cock cum, Nikki reached down and wrapped her hand around that big black thing and put it back into her pussy. I went back to licking her asshole, and while doing so I savored that cum, and the feeling of putting some of that cum on Nikki's asshole. That's when I realized-- oh shit, that precum is probably leaking into Nikki's pussy! It would NOT be okay for her to get pregnant tonight. Right as I thought.
