"I tied my magic to my virginity." Failiel explains. "If I have sex with a man, a bond will form..."

"And what does that mean?" Alexandra asks.

"...I'm not sure..." Failiel confesses. "I didn't read too much past the benefits of being a virginal witch. After all, all I really needed to know was that I'd regret giving in, and that all the boys I knew were jerks."

"Well of course." Alexandra agrees. "But that doesn't mean it's a bad idea to have one. No ideas at all about what will happen?"

"Well, I think I will remain a mage..." Failiel guesses, "but it could be a lot of things. The bond could mean I will just be a battery and the boy will cast the spells, or maybe I can't cast a spell unless he is near, or..."

"Well, let's find out." Alexandra breaks in. "Rick, open her."

"But isn't that being too cruel?" you object, until Alexandra turns a rather hostile eye on you, "...I mean...maybe we should look into this before we try anything drastic..."

"Well, if you don't want to, I'll let one of the other boys have some fun with her."

"But..."

"You might as well." Failiel breaks in. "I don't like the idea at all, but anybody else would be worse. You at least were brave and kind enough to step in the way when she threatened me."

"I did?" She has got to be confused. Likely she just moved behind you and somehow thought you were moving. Maybe you are brave, but moving between her and this terror would have been suicidal.

"Oh yes." she confirms. "You even tried to push me behind you. This may be overdoing it, but you definitely deserved a reward for that."

Impossible...but Alexandra isn't disputing the story. Not that you are at all sure what Alexandra would do in any case. But that would have been stupidly rash. You couldn't have done something so ridiculous.
Still, you are not going to turn down a piece...and if it makes Failiel happier with it... "It was nothing.", a statement that seems true either way.

"OK, let's get you ready..." You place your hands between her thighs and start to caress her most sensitive spot. She stiffens in shock, but Alexandra pushes her head into her ivory curls and orders her tongue into action. Reluctantly Failiel starts to kiss Alexandra's lower lips.
Failiel's reluctance at your end rapidly vanishes under your active fingers. Her excitement rapidly leads to a massive peak. "Well, that should mean you are ready. Now, just hold still..."
Get into position, push until you encounter resistance...push more, but gently...but not too gently. Then Failiel gives a gasp as her virginity comes to an end.
You start thrusting, still not pushing hard, and enjoying it greatly. Your emotions rapidly peak and you explode into Failiel. From her cry, Alexandra is also climaxing.
No reason to stop just yet. You resume pumping and once again go over the top, just before Failiel does.

"So now you are a woman, Failiel" Alexandra announces. "Now...
