Scientific Study

After washing down my husband’s body, he wrapped his hands around my waist and we talked tenderly about our desire for each other. I led him to the bedroom, lay beside him and relaxed my mind, gently running my hands along his shaft. It had been a long week of preparing for Christmas and we hadn’t had sex for a few days so were both eager for some intimacy. This story is a fantasy I shared with my husband during sex (which he helped me write).

He had agreed to participate in my scientific research, but due to the nature of the experiment, he was not aware of what I was going to do to him. He walked into the room and sat down.

“Lie down on the bench,” I directed in a slightly seductive voice

He looked up at my body, partially hidden by my white lab coat. His eyes became alert as he realized my slender legs were smooth and leading to somewhere enticing. My lab coat was fairly loose fitting and there was a possibility of him seeing more leg than was appropriate. He tried not to notice, but I saw a slight blush on his cheek.

I began running my hands over his soft, clean body, taking in the muscular shape of his arms and torso. I noted down a few observations on my clipboard and checked my lecture notes to ensure I was following the proceedings correctly.

My hands grasped his penis firmly and moved up and down repeatedly. He jolted with shock and a look of excitement appeared on his face. Things were going very well – he was responding in the way I had been expecting – his pupils were dilated, his heart rate had increased, his breathing intensified and his penis had become a solid, hard rod standing tall like a hot, fiery Bunsen burner.  I measured the girth and length of his penis with my hand.  I needed to understand how his penis was changing over the course of our encounter. After all, he had consented to all sexual activity on the paperwork.

While turned from him I undid my top button, for it was rather a warm day. I bent over him to get a closer look at him. My subject got a glance at my right breast just poking out above the coat’s lapel, but I didn’t mind as I was in control of the whole situation.

I lay next to him, kissing him until he was slightly breathless and begging for something to drink. But the only thing I could think of giving him to drink was my lady juices which were starting to lubricate my passage.  Just one lick was enough to revive him and prepare him for the next stage of the experiment.

Stage 2 of the experiment involved me getting out my scientific equipment. On a nearby bench, I had a navy-blue bullet vibrator which I applied to the tip of my clitoris in slow, circular motions. The sexual stimulation was intense and I needed my subject to share in this moment. He knew what I was thinking and climbed on top. I saw him hungering for my wet pussy and I led him towards me by grasping his member between my thumb and forefinger.

Feeling strong and powerful inside, a rush of testosterone gripped him and he felt as forceful as a missile hurtling towards its target.

“Faster,” I commanded whilst simultaneously switching my vibrator to a more intense setting.

My heart was beating so fast, and my breathing sped up getting quicker and heavier. I let out a few gasps as the intensely pleasurable sensations started to flow through my body. I felt like I was losing my control, in the grip of his strong body. He was almost too much to handle as he started rubbing my boobs and pinching my nipples between his fingers. Something I enjoyed very much, the mix of pain and pleasure concurring in my brain.  He continued to thrust inside me deeper and deeper, harder and harder.

Part of me wanted to allow myself to submit to him and to experience these intense feelings to take over my body, but I was the scientist and he was my test subject, so as part of my role I needed to maintain my integrity and hold onto my authority.

I gently spanked his bum and teased him saying he was my escaped dirty, lab rat needing to get back in his cage. Instead of calming him down to help me to regain my control it made him more eager to thrust his throbbing dick harder and harder inside me, causing me to let out a sudden squeal of delight.

He felt a growing sense of urgency and desire in his body, his penis wanting to go as deep as possible. Exhilaration took over him and finally, his penis released semen inside me.  A smile of satisfaction came over his face as he finished our experiment by kissing the nape of my neck, thanking me for such delightful sex and telling me he loved me.

It was time to put him back in his cage, ready to for another experiment in a couple of days.
