Sounding

I sat comfortably on the chair, yet my hands clenched tightly to its arms. I agreed to try this, sure, but I’ve never done it before. When I brought it up to her, she giggled and responded. “That’s okay, neither have I. But I have a guide here, and I bought this straight from the shop, so, it has to be good, right?”
She looked to the package, which read “Guarnteed to fill his desires.’ How cute. Now, then, I see you’re already a little hard.”
“We’re both naked already,” I pointed out to her, but she just shrugged and lowered herself to her knees. She pulled the small instrument out of the package. It was clear, probably plastic, maybe even soft. She squeezed it to see how it would spring into place, and when she was satisfied, she turned toward my cock.
The plastic thing with its rounded end brushed up against my skin. It only served to harden me further. I lift my hand up, but she protested, saying “You promised you wouldn’t touch. Do I have to tie you up?”
“N… no. Just a little nervous,” I said, placing my hand back down.
She nodded and brought the tip up underneath my glans. For the longest time, she swished it back and forth underneath the hood, touching that sensitive skin. But sooner or later, she had to get to the main event. Perhaps, it could be later?
The plastic tbe trails up the seem of flesh under the opening and soon enough, she pressed the head against my hole. I gasped as it enters in. For the first time, something went inside of me that way. New tingling sensations I never thought possible travel down my tract. I grip the arms harder, fingers clawing at it as I wait for it more of it.
With my cock stiff already, the soft plastic tube pushed in. Though there is some resistance, it slid deeper within as she focused intently on my shaft, watching as the slight bulge of flesh tells her where the tube has gone.
I tilted my head back, groaning out as pain flares from within me. Yet, it is a different sort of pain, an exploratory, exciting pain. Nerves fired up that had never been used this way, coming alive as the foreign object travels deeper and deeper inside of me. There is something magical about the body’s one-way exits. When we did our first anal play, it was much like this, yet this was much more intense. I could not help myself but continue to breathe in low and continuous moans. At one point, with the thing halfway sticking out of the head, she stopped, but I turned back down to her, with a gaze as if I had hearts in my eyes, and spoke plainly. “Keep… Keep going. I want, no, I need more!”
