Buying Time

I could feel the depth of penetration increase as the cock within me swelled up. Deeper and wider. That cock of hers was a damned sight better than my own equipment. One of these days I’d have to ask if I could be retrofitted with one of those.

“Variable width and length — that creates some intriguing possibilities, wouldn’t you say?” She chuckled, and I felt her cock shrink down inside me. Then it ballooned up again. Then… she was rhythmically *pulsing* it — bigger, smaller, bigger… It was like a heartbeat down there, inside my ass. My gut was booming like an echo chamber.

I would have come a dozen times by now, but the Sta-Hard implant wouldn’t let me. I was painfully hard and the pressure was building up inside me. I felt like screaming …

And once more she smiled. “I’ll have mercy on you. I can remotely trigger your implant to give you release, but first… ”

I felt the throbbing inside me quicken as she swelled up to maximum size. There was a cold wetness deep in my gut. She was spurting into me. Her orgasm, or what? Then I felt the electricity.

She was juicing me with an Electrovibe. It was shooting low-frequency AC current straight up my gut, and that tipped me over the edge. Now I was helplessly releasing my own ejaculate in gluey streams over my abdomen and chest. I moaned as we orgasmed together.

As she pulled out of me, a thick milky fluid began seeping out of my ass. It smelled faintly of lavender and honey.

“Yes,” she said. “My ejaculate is specially formulated to act as an antiseptic and anti-abrasive coating inside you. It prevents disease and soft-tissue injury, and also increases the elasticity of the intestinal lining. It’s scented to neutralize the fecal smell that all too often hangs in the air after anal sex. In short, it makes your ass eminently fuckable.”

I had also heard rumors that Androgen come had life-extending properties, but I was afraid to ask about that.
