“No hints! Just come over, kay?”
 
“Alright, see you soon. Love you.”
 
I suppose I should be nervous. Emi’s surprises are usually way out of my comfort zone. Last time, she blindfolded me and didn’t take it off until I was already strapped into the bungee cord. The time before that… Well, let’s just say I couldn’t walk right for a week. And today’s my birthday, so I’m sure she’s planning something “special.”  At least I know for sure we’re having dinner with Meiko and my parents tonight, so whatever it is can’t take too long. And unlike the damn bungee jumping, probably won’t cause a heart attack.
 
Regardless, I head back to my own dorm first, change into some disposable clothes (expecting the worst), and manage to dodge Kenji on my way out by throwing some marbles down the hall.  Without much further delay, I head over to the female dorms and make my way up to Emi’s room and open the door.
 
Wow.
 
I was expecting an empty room, followed by Emi jumping on my back – but what I see is far more surprising. Emi is lying on her back on the bed, completely naked, and demonstrating her trademark flexibility by lifting the central portion of her body almost completely vertical. Her stumps are resting against the wall, stopping her from slipping, as her shoulders are the only parts of her body actually touching the bed. She’s looking straight up from that position, as her hands are engaged in a complex task – she has a can of whipped cream, and seems to have written “19” on her butt, with one digit on each cheek. She finally notices me standing agape in the doorway and angles her head to the side.
 
“Hisao! You’ve arrived! …Close the door, will you?”
 
Still a bit stunned, I take a step inside and shut the door behind me.
 
“Uhh… Hi, Emi. What are you doing?”
 
“I made you a cake, Hisao! Happy birthday!”
 
A…cake?
 
“An ass cake?”
 
“Yep! Take a bite!”
 
A…bite?
 
“Come on, Hisao! Get over here and eat my ass!”
 
I require no further instruction. Unbuttoning my shirt so as not to dirty it, I walk over to the bed, kneel before it, and run my tongue up her left buttock, taking a good amount of whipped cream into my mouth as I do.
 
“Mmmm, Emi. This cake is delicious.”
 
“I’m glad you like it His-aaaa~”
 
Her words are cut off by a shriek of pleasure as commence my second assault, this time sneaking my tongue slightly into the crack between cheeks. Upon my third, I go straight up the center, going straight for her most sensitive area.  When I hit the spot, I know I’ve done it right. Emi convulses slightly, and loses her balance, falling backward, but I catch her. My left arm wraps around her chest, and my right hand lands between her thighs.  As I lean my head back to savor the taste of her, I begin to work my fingers: pinching a nipple with my left, and softly caressing her damp womanhood with my right. It’s curious how wet she’s gotten already – but who knows how long she’s been working herself up. She may even have been in this position when she called me.
 
“Getting excited, Emi? How long have you been like this?”
 
She opens her mouth to reply, but I don’t give her the chance. I slip a finger into her, and her face freezes in ecstasy. Rather than continue the motion, however, I leave my finger stationary and resume my feast. Her rear is still up in the air, and looking as tasty as when I walked in. Quickly, I use my mouth to clean off the remaining cream from her left, and give it a quick nibble before moving on to the right. Meanwhile, Emi seems to have regained some composure, and is grasping for the spray can where it fell. Whatever she plans to do with it, though, I do not intend to allow. Maneuvering my right arm to support her on its own, I move my left and grab the whipped cream before she can. Time for a little extra decorating, I think.
 
However much I enjoy munching on her behind, I pull off temporarily and lean to the side to look her in the eyes.  Her deep green eyes, so often reflective of her emotions, now betray her intense lust. She wants it; everything I can possibly do to her.
 
“H-Happy birthday, Hisao. I’m yours.”
 
Damn straight. And my birthday present needs a little more whipped cream. I pull her back towards me with my right arm, exposing more of her modest breasts; and with my free hand, I spray a small amount on each nipple.
 
“Come on, Emi. This cake is delicious, try some.”
 
She quickly catches on, and displaying more of her flexibility, hungrily lunges forward and takes a breast in her mouth, sucking furiously. I’d do the same if I could reach, but the sight of Emi enjoying herself reminds me what I have in front of me, and I return to her taut buttocks. The movement of our bodies has destroyed the shape of it, but there’s still a good amount of cream on her right side. I bury my face in it, licking all over until it glistens with my saliva and her sweat. But that doesn’t sate my hunger. I begin gnawing on her behind, relishing in its salty taste and firm texture. She yelps with pleasure, telling me she’s enjoying it too, and also that she’s long since cleaned her chest. I bring my left arm back around her body to act as a stabilizer, freeing my right hand to engage in a more forceful activity, bringing faster cries from my companion. I speed up my finger movements, and apply more power to my bites, and before long her moans are punctuated with short moments of utter silence, her breath catching in her throat as she climaxes.
 
Upon seeing my girlfriend orgasm, I ease down a bit, to allow her a chance to stop convulsing and catch her breath. She’s gotta be exhausted after that, righ-
 
Ow.
 
“Come on, Hisao. You’re not done yet.”
 
I find myself lying on the floor; Emi seems to have recovered much faster than expected, and launched herself forward into me, knocking us both off the bed. Her thighs have swung around and now grip the sides of my head, and before I can react she’s leaned back and grabbed my legs, immobilizing them. My arms remain free, but I doubt I’ll be able to rise from this position until Emi decides to let me. Looking up, I can see her trademark devilish grin, and know immediately I’ve lost all control of the situation. My only option now is to submit to her will, and address the new project she’s thrust into my face. My tongue begins moving instinctively, tracing complex shapes around her clitoris, and diving into her depths at carefully irregular intervals. The taste of her is intoxicating, and I find myself taking deeper breaths to allow myself more time buried between her legs. Meanwhile, my hands begin working my way up her body until they reach her nipples, which I pinch and twist lightly. She leans forward, putting more pressure on my face, and clasping my hands in hers.
 
Mistake.
 
I acknowledge my opportunity, and plunge my tongue deep into her as a distraction from my hands, which slide down her slim, sweaty body. Upon reaching her waist, I wrap my arms around her, pull my head back, and lift with my now free legs. In a second, I’ve taken complete control, and I drop Emi back onto the bed. She lies stunned at my sudden actions, allowing me to hold down her arms and climb on top of her. For the first time today, our lips meet. She tastes sweet, remnants of our earlier “prop” still lingering on her mouth.  Our tongues dance for what feels like an eternity, merely enjoying the flavor of each other. Eventually, I pull back, take a breath, and prepare to enter her. I thrust forward…
 
Fuck.
 
I’m still wearing my pants.
 
I slump back in defeat, and Emi begins laughing.
 
“You idiot. Here, let me help you with that.”
 
She dives forward, unbuttons me with lightning speed, and takes me into her mouth. I decide I’m tired of taking the lead, and merely stroke her hair as she eagerly wolfs down my entirety. She pauses, looks up at me, and manages another grin despite her mouth being full. Then, she resumes an active bobbing motion, while maintaining intense tongue movement within. I was already quite worked up, so it doesn’t take long before I’m ready to burst (also a credit to her skill). I try to utter a warning, but Emi ignores me, preferring as usual to take me down her throat in a single gulp. Finally, she pulls her head back, taking a deep breath.
 
“Feh. That part was less sweet than I hoped for. Guess I was just used to the other stuff, huh?”
 
“I think the can’s still around here, I could spray some down there for you if you want…”
 
“Nah, let’s just get to the good part, okay~”
 
With that, she jumps forward, and begins grinding her entire body on me in attempt to return me to a suitable condition.  We meet in another kiss, and just as it begins to intensify, and I feel the blood rushing to my loins….
 
The phone rings.
 
“Unnh.. Hisao, ignore it…”
 
I want to, but I should at least check who it is…. Mom. I reluctantly push Emi off, sit up, and answer the phone.
 
“Hi Mom. Yeah, I’m just getting ready. Okay, see you soon. Bye.”
 
“…Time to go?”
 
“Yeah.”
 
“It’s okay. We’ll finish this when we get back.”
 
Emi winks at me, and her smile shows me I’m going to be in for quite a ride after dinner. I only hope she doesn’t try anything at the table…
