You're aggressively making out with Lisa on the bed, so lost in the moment that you haven't even taken any of your clothes off. The pair of you are rolling around with each other lustfully, only occasionally taking care not to get twisted up in her curtain of hair or trailing silks.
The sugary flavor of the cookie hasn't left your mouth since Lisa first kissed you. Your lips and mouth tingle madly, though you barely notice in the heat of your passion. Your clothes are becoming an annoyance though, they feel extra loose and baggy. You could have sworn they were slim-fitting when you put them on.
You barely have time to ponder this before your gorgeous geisha grabs the back of your head and pulls you into another sugary, tingly kiss.
You both roll again, and Lisa ends up atop you, her legs straddling your waist. Parting her long hair, you see her almond eyes widen slightly before a smirk crosses her face. Her hands begin sliding beneath your baggy shirt, her fingers slowly dragging their way up your midsection to your chest. You stifle a strange urge to giggle at the feeling.
"Well well," she says in a satisfied, and slightly accented voice, "looks like that cookie still had some juice in it."
"Wha...?" you begin to say. You barely have time to recognize that your voice sounded different before her fingers flick across your nipples.
"Oooahhh!" you moan uncontrollably, slapping a hand across your mouth at the girlish sound that just erupted from it. Your lips feel softer and a little...bigger?
"Looks like someone liked that," says Lisa deviously, "Maybe some more?" She flicks your nipples again, sending a cascade of pleasure throughout your body.
Your eyes are now shut tight as you moan into your hand again, your back arches, thrusting your sensitive nipples towards your girlfriend as she continues to flick them.
After a short time of unbearably stimulating tingles, her ministrations stop. You open your eyes and up at her, her bright white face gazes down at you, she bites at her lower lip lustily.
"You should take a look at your progress," says Lisa with a wink.
Still reeling from her sexy barrage of flicks, you tilt your head and neck to look at yourself. You blink in amazement. You're smaller!
You weren't imagining your clothes being baggy, your shirt practically hangs off you now. It's hard to judge with Lisa sitting on top of you, but you'd say you could have lost half a foot in height. That still leaves you bigger than the new Lisa, but not by too much anymore.
As you lay your head back down to look up at Lisa, you feel a ruffling on the back of your head. Reaching back with your free hand, you feel your hair has grown much longer than the sensible length you usually keep it at. You take your other hand off your mouth and grab for your bangs, finding them disconcertingly longer. You pull a few strands down, finding they now reach into your vision.
From between the strands of hair you see Lisa giggling quietly to herself. Then, her eyes narrow and the devious grin returns.
"This is a good start, but I wonder if..." she pulls the hem of your shirt up, exposing your diminished torso. It looks much slimmer than it did when you got dressed this morning. Lisa then quickly ducks down and starts sucking at and licking your right nipple. Her right hand darts out and begins flicking and tugging at your other nipple.
You nearly scream in ecstasy, barely hiding it beneath strained moans. The tingling feeling returns with a vengeance. You can feel yourself getting smaller now, almost sliding through your tent-like clothing. Your legs have shrunk, pulling back from over the edge of the bed, and your feet are swimming in your shoes and socks.
Lisa switches her mouth to the other nipple, her left hand quickly filling in on your right side.
Pleasure arcs throughout your body, from your flexing toes to your wordlessly working lips. Your hands grip frantically at any parts of the sheets you can reach. You can feel your hair extending even longer, tickling the back of your neck.
You feel a pressure mounting in your chest, building and building. It spills over and Lisa is pushed up as your chest expands. She sits up and stares down in satisfaction at her handiwork.
Through a pleasurable haze, your half-open eyes stare down as your breasts bubble into being. They throb outwards in quick waves, each ebb and flow prompting fresh girly moans from your tingling lips.
Your new breasts top out at a B-Cup as the tingling fades away, leaving only your tender nips aching for pleasure.
Breathing heavily, you stare up at your girlfriend. She winks again, licking her lips with a tongue that looked pinker than was natural.
"Looks it still *has* juice," she says smugly, "let's see how you turn out."
She leans down and starts making out with you again. Any thoughts of protest die on your lips as they meet hers and the tingling begins anew. Lisa takes one hand and begins lightly tugging at at nipple again. Her other hand begins to slide down to your crotch...
