WOW! A few weeks later after a really enjoyable night, the Wife a little bit more sine than usual, finally arriving home whatever time! She told me... to make some more drinks whilst she went to the bath room and get changed, me thinking PJ's or a nighty, how wrong! She came down dressed in a very see through black shorty night, very shear black Lacey panties, her bra was a half cup type which allowed her nipples to poke over the top. Black stockings, with 6" high heels, She sexily walked. He flexed his hard-on and it became obvious that he was flexing his erection knowing that I was staring at his crotch, almost like an invitation.I asked David, “Hey, would you like a back massage?”Without hesitation, David replied, “Sure!”I said, “Okay, then just lay down on the floor,” as I pointed to the spot where he could lie down.As David stood up, the bulge of his hard protruding penis was very obvious. Rather than even try to cover it up at all, he stood there for a couple of seconds so. “Follow me then” I said and I walked down into a hallway that led past the security department to the restrooms. I went directly to the ladies’ restroom door; pushed it open and got inside, motioning the hesitant black guy to follow me inside.I locked the door and whispered in his ear:“Show me what you got…, I need at least ten inches of real man”I then sat down on the toilet and looked up at him.“You will not be disappointed, bitch!” He said as he opened his fly and pulled his trousers down to. By the time we reached her apartment, we were completely drenched to the bone. The clothes were sticking to our bodies. I could make out the contours of her body which were impressive. There were no lights in the building. The only light was from the emergency light in the lobby of the building.She informed me that she stayed on the fourth floor. As it was an old construction, there were no elevators available so we had to climb our way up 4 floors. She led the way and I could see her ass.
