He tries it out.

John opened the bag and let the object slide into his hand. "I have never tried anything like this before," he thought, "what is Sarah going to think?"

He studied the leather ring up close. It had a slightly ribbed surface, outside and in, and was quite firm with only a little bit of stretch. He wondered if it was wide enough to go around his cock, even though the lady in the store had shown him how perfectly it fit him. He realized it was just nerves; his wife Sarah had wanted him to try something to spice up their sex life, and this was about as much daring as he was capable of.

As instructed, he slid the ring down the length of his shaft and nestled it against his mound. The lower part dug slightly, though not painfully, into his scrotum.

He addressed the room. "Here goes nothing."

John stroked the base of his cock with his middle finger. It responded by starting to engorge, pushing the little ridges gently into him and ensuring the ring stayed in place. The sensation made his hard-on come harder and faster than usual; before long at all he was staring down at six inches of erection. And the motion of the ridges as he shifted position were already starting to stimulate him.

He couldn't help himself; John's right hand moved down and started stroking. With each caress of his hand he drew in a little breath, eventually letting out a gasp when his lungs were full. Eventually he was panting along with his anxious downward strokes, and when he occasionally followed with a return upward stroke he let out a low moaning howl of pleasure.

There was a moment of slight pain and then he came, a huge wad of cum spurting into the tissue he was holding just for the purpose. His chest fluttered and he breathed heavily from his orgasm.

"That was great; I can't wait to show it to Sarah. But that's enough for now." He reached down to take it off.

It didn't budge; not only that, his erection wasn't coming down.

"What the...?"

He pulled and tugged, but the ring might as well have been crazy-glued to his skin. He tried shifting and twisting it, but the all that did was pull his scrotum. Since John didn't like pain, he didn't try too much. Sarah was going to find out sooner rather than later.
