I fight the temptation to shove the dildo inside me right now, and instead I listen to Mark's voice on the phone, giving the orders.

"Lick the tip of it," he says. "Now draw it down your body, circling your tits."

I obey him, pressing the dildo to my lips and moistening it with saliva before dragging the smooth, slippery surface down onto my warm breasts. I tell Mark that this feels good, really fucking good. He makes me draw circles around my nipples, and I watch, fascinated, as they swell and darken the way they usually do under his hands. The gold dick, hard and shiny against the soft velvet of my skin, makes little dents in my tits, which spring back when I pull it away. We carry on like this for about five minutes until I'm so turned on I can hardly stand it. I notice my thighs beginning to tremble, a sure sign that all the tension in my body is building up and about to spill over soon.

"Please baby," I whimper, close to begging him. "I need you inside me."

"Well then," he replies, and I hear in the background the slap of his hand on his dick. I love the thought of him jerking and tugging his dick while its likeness penetrates my slit. "Talk me through it," he says.

"Okay. I'm on the bed, my legs apart and my pussy on fire," I tell him, encouraged by his breathing, which grows more rapid by the second. "I've got your hard, solid dick, and it's just outside me. I'm putting it in. The tip's in. It feels amazing, but I'm holding back. I'm just twisting it a little. It's cold inside me, and my pussy's so, so wet. I'm sliding it in and out of me, in and out, but I can't get it deep enough. It feels so like you, big, and hard, and I'm fucking myself, my pussy's just throbbing."
