Put on a show

"I'm going to put on a show for you," she promised me in a teasing sort of voice.

"What do you mean?" I asked.

"Well, just wait here and you'll see. And don't make any noise," Rebecca warned me. She exited the closet and closed the door almost all the way, leaving a slight crack. I saw her quickly undress and fling her clothes across the room. A minute later, her husband, wearing nothing but a towel around his waist, entered the bedroom.

I watched Rebecca stand up and bring him over to the bed. The towel dropped to the floor, leaving him as naked as she was. They began kissing passionately, their hands roaming over each other's naked bodies. My cock began to lengthen at this site. I barely managed to stifle a moan.

The scene became even more arousing as the couple shifted position on the bed. She lowered herself onto his cock and began riding him. I loved how her breasts bounced as she continued to ride him.

I moaned loudly at this. I quickly put a hand over my mouth, but it was too late. Her husband looked in my direction. Did he see me?
