The thong was no good because it was clearly visible through the dress. Even the knickers I’d bought specially to wear with this dress, the ones that were supposed to be invisible, showed through, so I had no option but to take the thong off and go commando. Feeling slightly self conscious I left the hotel room and went down stairs to the function. As soon as I got in the room I saw a couple of the lads from my firm and went straight over to them. Graham, who is a gorgeous, 6’2” young black man was particularly complimentary about the way I looked. I returned the compliments, because I have to say he looked extremely handsome in his suit. He was usually casually dressed in work so it was a real treat for me to see him dressed up. The evening passed successfully and as we reached the end of the event, people left the room and most ended up in the one of the hotel bars. Me and Graham were in the larger of the two bars sharing a bottle of wine and talking. I suspect the alcohol had given him extra confidence, because as I walked back in to the bar after a visit to the ladies, with a big broad smile he said to me, “I just have to ask you, what the hell are you wearing under that dress. You look amazing.” I leaned over to him and with an equally broad smile, whispered “Absolutely nothing. Can I take it you approve?” Within 10 minutes I had Graham in my room and on his back on my bed. I pulled his belt undone and struggled for a minute with the buttons and zip of his trousers, but soon I had his trousers undone. Fantastically, he was commando and smoothly shaven. I’d never in all my life seen such a wonderful sight. As I pushed his shirt up and feasted my eyes on his six-pack he pushed his own trousers down off his hips. His dick was fantastic. Huge and iron-hard with an amazingly large, well defined bell-end. I wanked him off for a moment as his hands gradually pulled the hem of my dress up and until he could get his hands on my thighs. He soon had my dress up round my waist and, with his hands on my hips he pulled me over so I could straddle him. Now, with my dress up round my waist and him between my legs I got myself in position to get this massive, ebony dick inside me. The feeling as his bell-end stretched me as he entered my wet hole was amazing and I was soon pounding myself down hard on to him. His hip thrusts matched my movements exactly and I soon had my first orgasm. I was loving the feeling of my braless tits bouncing under my dress as I continued to fuck myself on his meat. All too soon he stated to groan as I felt his dick harden and jerk inside me as he pumped his spunk deep in to me. I remained sitting on him and kept him inside me for a few minutes as I wriggled myself to a second orgasm while I enjoyed the view and the lovely feeling of his dick inside me. We fucked once more later that night, but this time we were naked and it was my turn to be on my back. A night to remember.
