I did so, she wrapped her legs around my head, pulling me down into her. As I began to feel her body tensing under me, I slipped away from her dripping sex and eased a long trail of delicate kisses up to her sternum. I held her breasts in my hands, tweaking and pinching her nipples with my fingers. Within moments, the nipples were swollen and hard. I traced small, tight circles around them with my tongue.
    "Cooper, make love to me," Sonia breathed. Her eyes were closed, and her head was cocked back hard into her pillow.
    "Okay, baby," I said and climbed onto to the bed, easing my body between her legs. Without effort, I slid inside her velvety sex. The sensation proved beyond description. She was tight, smooth, and hot along her canal. As I slowly pumped inside her, I could feel her muscles pulling and releasing against my cock.
    "Get my pins, Daddy," she said after a long time, the minutes flowing together in a series of ebbing and flowing sexual sensations. "On my nightstand."
    "What?" I panted.
    "I want my pins," she repeated. "They're there on my nightstand."
    "Okay," I said, and I grudgingly pulled my cock out of her so that I could reach what I finally saw was a small leather pouch on the nightstand. I retrieved the pouch and handed it to her.
    "Can we play with these?" she asked sweetly.
    "Angel, we can play with anything you want. What are they?" Slowly, I sank my shaft back inside Sonia's cunt. As I did so, she cooed and moaned.
    "They're dissection pins," she explained matter-of-factly, closing her eyes to savor the feeling our sexes created as they merged. She began to gyrate against my cock and fucked back at me in short, quick thrusts.
    "Dissection pins?" I breathed, thrusting hard into her. "What for?"
    "Yeah, you okay with that? It's kinda freaky, I admit. Please don't say that it turns you off. I need you on, baby, okay?"
    "Oh, I'm turned on. You don't have to worry about that. What do you want to do with the pins?"
    She licked her lips and sighed. I had to stop thrusting. It was too soon for me to come, so I withdrew from her cunt to rub my cock slowly in great circles against her clit and the rest of her moist butterfly. With each pass my hard glans made over her delicate button, she hiccupped with pleasure and gave a soft, plaintive whine.
    "I like my nipples stimulated. I want you to push the pins through my nipples."
    "What? Are you serious?" I exclaimed, stopping and letting my aching penis throb against her warm, wet opening. I looked at the pouch, and then at her. "I don't think I can do that."
    "Please, Daddy."
    "I don't think I can hurt you, Sonia. I can't do something that's going to hurt you."
    "You won't hurt me," she assured me, her tone much harder and more direct. She opened the pouch and pulled out two long, stainless steel needles. They were not thick, but they were long, at least six inches. "Pinch my nipples hard, and slide one of these through each one. Endorphins, Coop! I won't hurt. It'll feel so good."
    I took the two needles and leaned over her. "Are you completely sure?"
    "Yes, it's like getting a piercing," she moaned, tugging my cock now with her hand. "And when they're through my nipples, I want you to fuck me again. Hard. You're not going to hurt me."
    "Okay."
    "In my asshole," she clarified. "I want you to fuck my ass."
    My cock twitched at the lewdness in her tone and at the thought of entering her ass again. I slipped myself inside her once more and stole several quick, illicit thrusts.
    "Coop," she complained. "Focus."
    "Okay," I smiled. And I had to admit to myself that I was getting incredibly excited again, after the initial cooling down of my passion by her somewhat unconventional request. "How do I do this?"
    "Just pinch my nipples really tight and then push the pin through. Nothing to it." She opened her eyes and gave me a look that said it was going to be all right. "Just when you break the skin, keep pushing until it's through."
    "Okay," I said. Taking her left nipple
