Dean nervously began trying to take off the Super-Stud Monster-Thong, hoping he'd find that the freakishly enormous package he now seemed to posess, wasn't real.
Unfortunately though he already knew it had to be, since he could actually feel the immense, and now increasingly erotic weight of his genitalia massively pulling & hanging down from his crotch, swaying slightly yet heavily as he started to move...he could also feel the incredible sensation of all that cock & ball flesh pressing hard against the inside of the leather pouch trying to stretch it out even further!
As Dean was obviously still pre-occupied; Mark saw something out of the corner of his eye lying on the floor next to him. Picking it up, he suddenly remembered that it was that other strange pair of underwear he had found earlier. Originally he was going to give that pair to Dean to try on, but then he saw that 'Monster Thong' hanging on the rack almost right beside it, and immediately changed his mind. Mark realized he never put the other one back and must have dropped it on the floor when he first handed the thong to Dean.
Mark picked it up and read the label, "Big Dick, Super-Bottom-Boy Briefs...All size-queens say 'there's no such thing as too big', but none of them really mean it. With the BDSB3, you'll be able to prove that statement true...the life of a horse-hung 100% TRUE size-queen is waiting for you!"
Holding them up, Mark saw that they looked almost like a normal pair of cotton/spandex 2Xist black briefs, except the pouch in the front looked to be about double the size it would normally be. Also, the back part that would cover your ass had a seem going up the middle and the material on each side of the seam was very baggy as it hung from the waistband, but it seemed to pull tight as it reached the sides and the elastic around the leg holes at the bottom.
Glancing at the label again, he noticed that the instructions appeared to be almost identical to the Super-Stud Monster-Thong.
