A loose thread

David put the sheet on top of his naked body making a hole for his head and with a few knots, the sheet served a lot, except for the part from the knees down, since the sheet was not very long it covered almost everything except David's muscular legs.

"I don't think this works, I feel the sheet going up my legs" David looked at the sheet doubting whether he should stick with the plan.

Greg was behind everything, from the first moment David put on the sheet, Greg had begun to pull the loose thread of the sheet, in just five minutes and without David realizing he had removed 10 inches from the sheet.

"Don't worry man, we will get through this if we hurry" Greg smiled to himself and started to cheer David to go out of the closet and start walking to the exit and into the car.

David was red with the embarrassment of being naked except for the sheet, which seemed to disappear with every passing second, not imagining that it was all due to his friend Greg.

Greg just smiled, he had found another way to unwrap the knot of the sheet, if Greg pulled from behind a seam was unstitching, the seam that held the sheet together on David's back, that gorgeous back and rounded soft ass.

David opened the door and Greg went after him, people turned to see him but no one stopped much given the large amount of **** in their bodies.

But Greg was almost done with the sewing of his back, David hadn't bothered to make big knots and when Greg finished peeling the seam off his back, the sheet was held together simply because David's body was stuck to it.

At that moment Greg saw the opportunity, when they were near the front door, Greg saw a nail coming out in the door frame and when David opened the door and was ready to leave, Greg nailed a part of the sheet into that nail, it would only took a push and David's whole body would be exposed to whoever was on the other side of the door.
