Instruction

 

I watched nervously as our sex therapist pushed down on my wife, slowly slid his thick, hard cock into her obviously soaked pussy. "Oh fuck," she moaned, her eyes fluttering then closing as she started to shake. "Oh fuck."

"Like this," he said, "you find that spot inside her, right there, that's when you thrust harder and faster. It's obvious she can cum from penetration if placement and technique are correct and you take your time."

I looked at my wife, the bliss on her face. We'd tried this very position last but without success. "I...we...we tried this," I said.

"Watch," he said, "like this? Long, slow, powerful thrusts?" He pushed in and out of her; she continued to moan, to shake, to mumble, to beg him to fuck her.

"Kind...kind of," I said.

"Do you feel a difference, Christina?" He asked my wife.

"B...b...b...bigger," my wife said.

"Bigger?" he asked.

"Th...th...thicker...l...l...longer."

I looked at his cock and had two thoughts. First, it was obviously much larger than mine. And second, he obviously had stamina I lacked."

He looked over at me, watched me watching him. "How long?" he asked.

"How long?"

"Do you last? You tried this position, right? She responds, how long did you last?"

"I...I don't know...a...a minute or...or so."

Christina opened her eyes. "Not a minute," she said, teeth chattering.

He smiled at me as he slowly but forcefully moved his hips to drive his cock in and out of my wife. "You can't do anything about your size," he said, "but you need to work on stamina. Even smaller men should be able to make a woman cum in this position if they can last."

"He can't," Christina moaned, "he never could, he...oh, fuck!" He pushed her back down which made the angle of her hips change and she was shaking, cuming again, even harder. "Oh, fuck."

Suddenly he grunted, thrust harder and faster until he called out, some primitive moan, thrust his cock deep in my wife and held it there. I could see his balls pulsating as he emptied himself into Christina. There was something about the way he held her, like she was his, a possession to use, and her response, her orgasm deep, urgent, powerful.

He held himself in her for a minute, two, three as her orgasm continued, slowed down, eventually ending. He looked at me, nodded. "That's what she needs, weekly," he said.

"I...I can try," I said.

"No, you misunderstand. You shouldn't, not anymore, we'll set up a weekly session on Saturday mornings at 9. That gives you time to get her showered and ready."

"Ready?"

"I'll take care of this part," he said, "you continue what you're good at...pampering her, preparing her, pleasing her with your mouth and hands; I've got this part so you just focus on your part."
