A writing exercise

"Can you see it?"
Her words brush across the back of my neck. I felt her arm snake around my waist. Her thumb brushed against my navel. I wasn't wearing a shirt and neither was she. I put my nose against the chilly glass of the window and focus on what is in front of me.
"Oh" I respond when I see it. "Oh how cute!"
She chuckles softly, places a soft kiss at my hairline. I shiver with the resulting goosebumps.
"It's just a squirrel." Her  other hand finds itself on my hip. I feel the cotton of her underwear brush against my butt.
"Look at him go." I say, even as her thumb begins a feather like stroke over my lower belly. I feel her nuzzling her nose into my hair and we sway. The nut brown squirrel pauses and his tail twitches once... twice. His big black eyes surveying the barren winter landscape for potential danger. He seems to decide it's safe and he darts along the grass. He stands at the base of a tree now and begins to dig. I close my eyes as she presses her lip just under my ear.
"You hungry?" She whispers, and kisses the side of my neck.
"Mmhmm... I could eat a stack of pancakes." 
Another raspy chuckle and her hand moves from my hip to just below my breast. The thumb on that hand brushes the curve of my left breast, sending a delightful tremor low in my belly.
"I was thinking about having something else on the menu."
I lick my lips. An answering pulse begins between my thighs and I take a breath, letting it out  with a tremble. "You are such a lecher"
"Just watch the squirrel" There is a ring of amusement in her voice, her thumb ceases brushing my navel and instead moves lower, brushing just above the rim of my underwear.  We stand here like that. I have no words. One thumb continues to brush under my right breast while the other thumb runs the rim of my underwear. It is deliberate and rhythmic.
With each sensual graze the temperature seems to rise.  I try to focus on the squirrel. His tail flicks and he darts over to a scraggly bush. He begins to dig just as she kissed my shoulder.  The kisses don't stop, they work their way up to just below my ear.
The stroking of thumbs.. the feathery lips... the twitching of a chubby squirrel's tail. My heart races in my chest now. I can hear the ticking of the wall clock downstairs. We sway again and the hand under my breast shifts up. It brushes over my nipple. I take in a lung full of air, hold it, and then release it with a shuddering of shoulders. 
Her grip on me hardens, and my back is treated to the softness of her breasts nestled against them. I know better than to speak. She gets joy from this sensual exploration. This deliberate torture.
My nipple hardens under her touch and a fresh burst of arousal sends my knees trembling. She shifts that hand mercilessly teasing the rim of m underwear upward and now she has the full weight of my breasts in either hand. I almost sigh with the exquisiteness such an action evokes. The startling sensation of millions of receptors responding to the tiniest stimulation. This time I am pressing against her... I lift my hands up to hold hers there.
"Uh uh... watch the squirrel."
I grunt my frustration and place my fists to either side of my hips. She does not laugh but I feel the amusement from her lips, which are pressed against the back of my neck. Involuntarily my knees drift a little more apart.
The squirrel dives under the bush, only to return seconds later. He lifts up an acorn. His tiny hands turn it over and over.
She kneads my breasts, then slides a single hand over my stomach, torturously slow. 
"Honey... " I say huskily. "this is so wrong..."
She tugs one end of my underwear down with her hand. Her pointer finger slides along the seam where my thigh joins my hip, then slowly across to nestle right where I want her. I suck my teeth. I  can't move. If I thrust my hips forward she'd touch my throbbing clit. Yet if I did that she'd  make me wait more. This is a game we play. A test of endurance. If I win I get a pay off. If she wins...
We sway again and she's tugging the other side of my panties.  They stop  low on my thighs. Her hands move to my hips and rest there.
I respond with a whimper.
The squirrel looks around, puts the nut in his mouth, and makes a dash across the street. He disappears behind a fence.
I can hear her breathing. Thumbs circling my hips. I can feel her pressed against me still.
I hold my breath. I am pulsing. My blood rushes in my ears. I am heavy with need I can feel it... but I must stay still. I must win. The clock seems louder but the silence between us is profound.
She presses a kiss against my shoulder. Her hands drop from my hips.
Everything becomes suspended. I am waiting now. Though I don't know how much longer I can hold out.
"Turn around" she says huskily.
