"Go on," I said, smiling. Logan kissed down the valley of my breasts. He proceeded to lick the underside of my mounds upwards to my nipples. Taking first one, and then the other, into his mouth, he suckled softly and nibbled gently. I let out a soft moan.
Logan gave me a smile and moved to my feet, nibbling lightly on my toes before kissing his way from my feet up my legs. I moaned louder as he reached my thighs, kissing and licking up the inside. I was anticipating him heading for my treasure box, but Logan instead turned me over.
"I still have to kiss the back half of you, Jenna," Logan whispered. "I'd love to drink your nectar from the source, but this comes first." He moved his way up the back of my legs, and I discovered that the back of my knees was a ticklish spot. He then moved down my neck to my back, and when his lips and tongue ran up and down my spine, my body began trembling with pleasure.
Finally, he turned me back over and slipped his tongue inside my soaking box. When Logan's fingertip began circling the bud of my clit, I lost control and flooded his face with nectar. He licked up as much as he could before moving up to kiss me on the lips, letting me taste myself as our tongues twined.
"You taste wonderful, Jenna," he purred when we broke for air.
"My turn," I said. I laid his body on the bed and kissed from his neck to his chest. I wasn't going to give him a total tongue-bath, but I did want to give him a reward for doing such a wonderful job. I nibbled his toes and kissed his thighs while I ran my fingernails over his flanks.
When I felt him to be ready, I slipped my tongue onto his swollen balls and wrapped my hand around his thick organ, stroking softly up and down. Logan let out a gentle sigh. "I'm ready now, Jenna," he whispered. "Take me."
I teased him for a few moments longer before I lay down and spread my legs. Logan positioned himself between them and slid into me. He wrapped his arms tenderly around me and slowly slid in and out, establishing a smooth rhythm. I was expecting him to pound away, but he displayed admirable restraint, instead controlling his body and taking care he wouldn't crush me.
After he had made me climax several times in the missionary position, I decided to switch. Logan lay on the bed and I mounted him, leaning forward so that my breasts were presented to his hungering mouth. He took them and suckled on the nipples as I bounced up and down.
Unlike Logan, I did not go for a slow and steady rhythm. I wrapped my legs around Logan's body and increased the pace, first to a fast one and then to as furious a pace as I could manage. Logan's hips moved in tandem with mine. "Oh, Jenna!" he moaned. "You're so... forceful. I don't know how I'm able to hold back!"
If it weren't for my magic, he'd have already filled me up. I did desire his cum inside me, but at a moment of my choosing. I felt an orgasm more powerful than any I'd had that day approaching. "Don't try to hold back, Logan," I gasped. My body went into a violent spasm. "Fill me1 Give it to me, now!" My words broke the spell and Logan shot jet after jet of his cum into my superheated box.
After we were both finished, I collapsed onto his body, with Logan still inside me. "Wow, Jenna," he whispered. "That was the most amazing experience I've ever had."
"You were darn good, yourself," I purred. I untangled my body from his and lay next to him. We fell asleep holding each other.
The next day, a carrier pigeon arrived with an urgent message from Professor Mobley. When I arrived in the Fortress, he was very agitated. "If this entity creates a collection of 500 spawn in one place," he said, "they can break into the Fortress with their powers. Jenna, you and Logan must prevent this. If you can destroy the entity in the River, it will prevent more spawn from being formed. The good thing is that this town isn't a tourist destination, so there won't be a lot of new victims formed around here. The bad news is that based on these news reports, the contamination has spread far and wide. Infected spawn are spreading from the towns all along the River, which include 10 major cities, and taking the contamination to the rest of the world. I estimate that within 6 months, most of mankind will be gone."
The professor's prediction was indeed accurate. Aside from the most remote parts of the world -- the Eskimos, the Bedouins, some parts of darkest Africa -- the Fortress was within a year the last bastion of humanity, as far as we could tell.
Logan and I scoured the area around the Fortress daily, eliminating any spawn we could find. So far, we have been successful in purging the threat. Logan thinks that within a year, we will be strong enough to destroy the entity in the River and make the world safe for the residents of the Fortress. The spawn created must feed on human blood within a year, or they will die off, so if we can succeed...
Oh, one more thing. At least once per week, Logan gives me what I need -- long, passionate sex sessions, and a few drops of his blood.
