Waiting until Jack's head was down, John put on the gloves he'd just thought up. The leather felt deliciously soft against his skin. He flexed his hands a few times, enjoying the way the leather stretched over his knuckles, before turning them palm upwards. The business end of these particular little toys.
The sharp tack points covering the surface weren't immediately visible unless you knew they were there. John wiggled his fingers, and saw the slight glint of the metal poking through. Each tack was only 1/8 inch long, but with 96 of them and in the right hands, or more precisely on them John knew exactly what sort of damage they could do.
Just right thought John, grinning, before walking over to the bed. He took off one of the gloves, placing it next to Jack's hip for now. He drifted his ungloved hand up Jack's spine, until he held it firmly on the back of Jack's neck.
"A taster sweetheart. See there's something I thought you might enjoy." Placing his gloved hand gently on Jack's back, still holding the back of Jack's neck with the other, he paused. Letting Jack feel the warmth, and soft sensation of the leather, and the prickle of the points just resting for now.
"These gloves are known as vampire gloves Jack. Wanna' know why?" He trailed his gloved hand down the curve of Jack's back, just letting the points tickle and scratch.
