You are quite aroused from stimulating Kallen's lovely knockers and as you move on top of her, your stiff member brushes against her thigh. Kallen reacts nervously at first to the inadvertent touch, but is soon distracted by your fingers tickling around her pits.
Her sensitivity here makes her prior reactions seem restrained and lackluster. She screams with laughter and her entire body convulses from the pleasure. This has the unfortunate effect of causing her leg to bang into your groin. "Oouu," you groan and lean over in pain.
Kallen, realizing what happens, blushes. "Zero, I'm so sorry. I swear I didn't mean too," she says sincerely.
"It's alright, Q1. I can scarcely blame you when you're blindfolded and I'm making you quiver so," you assure her. You are unable to resist cupping her shapely melons as you conclude your acceptance. At first Kallen seems like she is going to laugh loudly and shake again, but then she reacts in a more lascivious manner.
"Zero, does it still hurt?" she asks, lightly biting her lower lip as she does.
"Just a little. You shouldn't--" you start but are interrupted.
"May I kiss it and make it better?" Kallen teases, in a breathy voice you were surprised she could manage after the extensive tickling.
"Kallen. Are you sure? I--" you say, conflict in your voice.
"Please take off the mask. I promise I won't disturb the blindfold," she interrupts again and sits up to puts her arm on your shoulder and then moves it up to your mask. Since she is contacting it, you nod. You remove the mask and toss it aside. You reach over and bring Kallen's arms, and then tickle her armpits some more. Sorry, Kallen. But I need to do that first, you think. Kallen reacts as loudly and actively as before.
"I really should have expected that," she says as you stop and lean in for a lengthy and passionate kiss. You make out with your Red Lotus for some time, your tongues and lips exploring each other as your hands moved over each others bodies. You separate from her mouth to kiss over her body. You start with her feet, which she squirms when you do, of course. You move up her long, strong legs, her curvy hips, her taunt stomach, her full breasts, and her soft neck.
"I think I should make good on my offer," Kallen says and forms a playful grin. You wish you could look into her blue eyes, which contained all the less physical parts that made you desire her: her driving passion, her understated intelligence, her strong empathy. You resist making a sigh at the necessary lack of intimacy between you and your soon-to-be lover. Still, you feel guilty thinking about how Kallen Kouzuki would respond to knowing she was going to be giving head to Lelouch vi Britannia.
You silently shake your head as Kallen reaches out gently with her hands and begins fondling your balls and your member. Kallen is your subordinate in many ways, but in perhaps more important aspects she is your equal or even superior. She is another creature of alias and disguise, who has been a comrade in arms, who is another young person who wishes to be carnal with a partner she cares about. Besides, you are much less a Britannian prince now than she is a Britannian student.
Kallen licking over your groin voids any pondering you have about the concept of identity. Your left hand runs through her gorgeous red hair while your right hand caresses her breasts. They are so beautiful, you think.
Kallen sucks on your balls, one at a time. She then massages them as her mouth move to the head of your tool, and takes it in. You don't want to express sexual dominance (there is certainly enough of it from receiving blindfolded fellatio), but you move your right hand to the top of Kallen's head. You don't apply pressure, but take in her heads movements as she moves it deeper down your member. She sucks harder and then starts to hum a little. The vibrations are too much. "Kallen, I'm--" you start to warn.
Kallen, in a final interruption, nods her head slightly, and increase her speed. Your emission is more than either of you expect, and Kallen ends up part swallowing, part spitting, and part dripping from her chin. You use the blanket to wipe her chin and lips before sharing a powerful kiss.
"I hope that did the trick," Kallen quipped.
"I'll look to bang my groin constantly if Dr. Kouzuki is always will to heal," you retort back. Kallen made the first non-tickle induced laugh you had heard that night. It reminded you of your original intent. "Well, shall we continue with me tormenting you with tickles or should I reciprocate?"
