This story continues directly on from the end of part 2, with Kat passing out and Alex having not gotten his own release yet...
I leave the room, pacing the hallway with a nervous energy and caught in a trap. Not because I have any illusion about fixing this situation, or somehow thinking I can be faithful still. No I'm pacing because I need to do something physical. I can't mess with her in her sleep, that's... much less satisfying. I want her energetic when she finally feels me cumming inside her.
I repress a groan, picturing my orgasm. I turn around to pace once more and see her bedroom door is hanging open. I don't hesitate before I slip in the empty room. Her pillow is still there, coated in her wetness from her unsuccessful attempt to get off. I hear a faint noise, and spot a pair of discarded headphones, upon picking them up I hear a woman moaning in abject pleasure.
I turn on her monitor, only to see that the same cartoon of a succubus is playing. This time she's with a guy and a girl, the subtitles have her helpfully explaining that she just needs to borrow her boyfriend. My pants tighten, and I tug them loose to drop them entirely, leaving my naked body free. Nothing worth hiding now.
I watch transfixed as the boy is enamored with the succubus, obeying her every command as he stuffs her holes one by one. I'm mesmerised by the idea of Kat being such a closeted pervert, loving stuff like this.
I get an impulse to check what else she's been having fun with as I walk over to the desk. I pause the video, and go to her browser to see if she's careless with the history. I'm licking my lips with anticipation when I see her current tabs look mundane. Just instagram, a cake recipe and then a site for ordering... an aphrodisiac?
I click into that tab, reading the scant product description. "A spicy powder to draw out the libido in anyone. Recommended for sexual therapy, to spice things up with a partner or to give yourself an extra special night. Follow dosage instructions carefully to ensure you don't exceed tolerance."
My mouth is dry. I would laugh at the idea, because aphrodisiacs don't work... but I am naked, having made my girlfriend's sister pass out just from my tongue. I gently touch my cock and feel a shiver wash over me. I test out the thought, the idea that Kat might have violated me, manipulated me and made me go over the deep end like this.
It's so fucking hot.
I pull my hand away from my cock. I can feel it stiffen, aching for contact. But I want to save it, let her touch it. Let her feel what she's done to me.
I go over to Kat's mini fridge on a hunch, and I open it. There's no cake here, but I find a bowl of icing. A sticky note on it that just says "4x" and a face with a tongue sticking out. I dip my finger in and suck. Similar to the cake but, there's a strong spicy kick in this. One I absolutely would have noticed. As I suck it off my finger, I feel my cock throb, itching for use.
Four times strength... well it's time she got a taste of it herself.
I return to my room with the bowl, and find her still passed out, gorgeous and naked. I'd be impatient to wake her up, if I didn't have something much more fun in mind.
I walk up to her exhausted form and sit on the bed next to her. She breathes slowly, fully out of it. I run my finger through the icing and bring it to her mouth. Her lips are only slightly parted so I quietly coo "Be a good girl and open up."
Her mouth opens wide and I feed her the icing. Her tongue responds, meeting my finger, and a hitch in her breath. I use two fingers the second time, scooping much more for her. I slide them inside of her mouth and her tongue is desperate. Cleaning me off in a matter of seconds. I feed her more, her mouth and tongue never hesitating.
Partway through I wonder if she's pretending to be asleep and playing along, but when I whisper her name and set the bowl down on the side, she just lays panting, mouth open and expectant. I give her what she craves, another sweet covered finger for her to lap at. I can even feel her hips shifting in anticipation.
I'm wondering how to feed her much more, when I feel a buzz in my pocket. I hurriedly step outside, not wanting her to wake up prematurely.
It's Allie again, and I don't even feel bad about being annoyed as I answer. She wants to have a proper chat rather than a hurried update. I head downstairs,. My frustration simmers, but I keep it out of my voice as we walk. I head downstairs to be far away and I start pacing to keep myself doing anything physical, since I'm not having the satisfaction I crave more than anything else.
Allie starts telling me about her trip for work and how well it's going, that it should give her more time at home now that she's finally settling this. My mood thaws as I let her lead the conversation and I start to take my mind off the naked bombshell in our bed, and I start to remember how I love my girlfriend.
We start talking in earnest, I only give her an edited version of what me and Kat got up to. 'Just watching stuff'. I'm still pacing naked and with my cock rock hard, but I'm at least able to act normal for my girlfriend as we banter.
It's some time before she eventually has to to hang up and return to her work. She says to 'say hi to Kat' before she hangs up with a click. I feel a tension in my gut, with none of my neediness gone away, but it's complicated by Allie having re-entered my thoughts.
I try to swallow the intense desire, and keep it in check as I walk back o my room. I know I won't be able to pretend nothing happened, but I cling to the idea that I should at least talk with Kat. I open my door and see her.
She's awake.
Sitting up.
Sucking icing off her finger.
She's covered in icing, spread from her collarbones down to her hips, except where her finger has swept through to write "eat me" as she looks at me intensely.
"I can't
