"We can try missionary..." you suggest.

"No..." Failiel answers. "Somehow that sounds wrong."

"Well..." you consider, "you could try cowgirl..."

"What's that?" the puzzled lass asks.

"Ah..." you try to figure out the proper way to explain to this almost virgin, "The girl gets on top and does the work."

"Yes..." Failiel considers in a surprisingly serious tone, "That seems right. Let's do it."

Surprising that she wants such an active role, but why should you object? You lean back, "OK, climb aboard." Failiel does so, sitting on your knees facing you, but doesn't seem to know what to do next. "Just move up my legs...no, don't get up. Let my legs slide against you..." As you hoped, the contact is rather stimulating and while Failiel is quite negative at first, by the time she has reached your tool, she is smiling. [Your soldier standing at attention right in front of her womanly center almost makes it look like she is the boy.]
However, the idea of sheathing your sword in her most sensitive spot scares her, and so you work to soothe her. "Now just lean forward and give me a kiss..." She does as told, and you kiss back, and caress her huge mounds. "Now move your hips from side to side..."
The erotic contact has its expected results. Failiel's excitement builds and builds until she goes over the top. That is a step or two after you do, but that means you are able to get hard again without any great break in the action. "Now raise your hips... Hold still while I get my man in position. OK, lower...slowly. Hold a second... Very good. Now start sliding down, slowly. Everything is going to be pretty sensitive here..." Failiel again follows orders, which is almost agonizingly pleasant for you as she covers your shaft to the hilt. When she gets there, she pauses, looking rather pleased with herself. "Now rise up, again slowly and not too far... Yes, very good... Again down, and up...Just keep it up until we attain completion..."

Actually you attain that twice before Failiel is finally stimulated into a powerful climax that leaves her sprawling on you, and smiling. "Not all the things that are going to happen to me are going to be bad." she judges.

"We'll see about that." Alexandra announces. "Right now I'm curious about this bond you were talking about. So we are going to do some experiments. Come along."

There really is no choice. [Well, not absolutely true. There are about a dozen other girls following Alexandra, all looking at you and drooling. They are clearly hoping you try to give Alexandra some lip.] You scramble off the cot and follow the head of the house.
