My trainee, Anna, stood beside me, to my right. With her left hand clutching my right ass cheek through my jeans, she ran her middle finger along the crease of my ass as she expertly petted and patted my bulging front.
Anna is a sweet young lady, about 5'4", slender and athletic, an exquisite face, firm sweet ass and long lovely legs. She was wearing her little school girl skirt and white men's shirt on that spring day.
Demonstrating her excellent skills and training thus far, she moved things along. Unbuckling my belt with one hand, she unzipped my pants, spread them open at the fly, and gently brought my rapidly hardening manhood out into the air. Her touch, as always, was light but firm. Her hands were small and delicate, the hands of a young lady. They were warm, feminine, and very skilled. My pants, weighed down by my belt, fell to the floor. Keeping one hand on my cock just as she was trained to do, she pulled my briefs down.
The cool air of the classroom felt delicious against my bare ass, balls and cock. My trainee stood still fully dressed in her private school skirt, white collared shirt, and mesmerizing smile.
While stroking my throbbing length with her right hand she reached through my legs from behind and heft my full, aching balls. "Mmm," she cooed, "my stud is quite full today, isn't he?"
As an answer, I leaned toward her face and shoved my needful tongue into her panting, open mouth. Her breathing quickened, thrilled at my lustful, demanding kiss. While clutching my cock with one hand and cradling my full aching orbs with the other, she fairly melted against me, such was her arousal. I could almost smell the enticing scent of her wet pussy even through her clothes.
Yes, Anna was a hot little number. My trainee. At 18, she was young and eager to please. The girl I could tell anything to, including my risque fantasies involving her fellow students at a northeastern school for girls where I taught History, Civics, and . . .
Anna began to talk about the girl we both watched through my classroom window - Sara, sweet sexy young Sara, standing maybe 25 feet away, next to a water fountain. Sara was talking to her friend Pam. Sara: Senior cheerleader and all-around beautiful hottie.
"She has a very pretty face, doesn't she, Master," Anna whispered. "I think you probably like her pretty mouth best of all, don't you?"
"Indeed, my sweet pupil, Sara does have a hot little mouth. I like her hot legs in her uniform too. I love the slits in her skirt."
"Mmm-Hmm," Anna moaned. "She does have very pretty legs. Her thighs are so toned, they don't even touch up top, do they? Does Master like her pretty breasts, too?" Anna queried.
I looked at the swell in Sara's little cheer sweater and thought of the loveliness that lived within. "Yes, I really love her titties.... they aren't too big, but just right."
"Mmm, I bet you wouldn't mind seeing me lick her nipples, would you..." Anna whispered. 
"I'm sure I couldn't resist biting and pulling on them like you do mine, sweet stud."
Anna's hand which cradled my full and lucky balls from the rear now came to her lips. I glanced at her. She gazed smokily into my eyes as she whetted her middle finger, sucking on it like she sucked my cock. After getting her middle finger wet with saliva, she returned to my behind, spreading my ass cheeks and nuzzling between them. Anna explored, rubbing my hole sexily, then nudging it up into me and wiggling it. I arched my back and bowed forward a bit but never took my eyes off sweet hot Sara.
"There's my good girl," I moaned. She worked her finger in and out of me just as I'd trained her.
"Master, would you please let me lick you down there, if I'm a good girl?"
I leaned over toward Anna and kissed her on the mouth again. Our tongues entwined and I licked her open mouth in sensuous reverie. "Good girl," I whispered. "Sara is so cute, and I really love that you are jacking me off like this while I watch her."
Anna's breathing became quicker. "I love to jack you off, Master, especially when you are looking at a girl we both admire. Sara is fucking hot..." she panted as she stole another glance toward the oblivious hottie. Anna's busy, buried finger picked up pace, as did her jacking hand. I was getting very hot.
"Please master, are you going to let me lick you back there?" Poor Anna was desperate for me to respond. I teased her, ignoring the request.
Her desperate arousal was clearly evident. The dear sexy plaything gets totally turned on when jacking me off, licking my big balls, and more. Her sexy hips begin to flex in a brazen fucking motion, so I suggested, "Is my pretty girl ready to cum?" She groaned in agreement. "Then she shall take her pleasure now," I whispered. Crying out like a sexy angel, she quickly came without any physical stimulation of her own, except maybe the lovely soft texture of her hot little panties. I do love when she rubs her sexy pussy against my leg or foot and cums at my request while licking my big cock.
I reached down and nuzzled my hand below her button down men's white shirt and lacy little bra and find her nipple. I pinched the delicate young tit, pulling on it fairly roughly. Anna cried out in pleasure and pain, cumming again. Her lovely orgasm made my cock throb, so I grabbed her hair to bring her mouth to me... I looked down to she her hips buck as her orgasm subsided. I praised her, "There's a good little whore." She smiled sweetly. She loves when I call her a whore and a slut.
"You're such an amazing stud," she panted, her hand gripping my cock firmly and tugging. "Every girl in school is wet all day long just wishing they could hold what I have in my hand, and they swoon at the very idea of maybe being lucky enough to have you fuck their tight little mouths..." She neared another orgasm. "My beautiful Master, I'm such a lucky girl." Her panting was intoxicating, her hips flexing, her back arching.
She cried out and came right then as her finger drove deeper into me and her hand stroked steadily. "Oh! My god," she moaned. She was aching for a fuck, and I said as much.
"You need a good fucking, don't you pretty girl?" I whispered.
"Yes, I do, Master," she cooed, her eyes looking longingly at my cock in her delicate little hand. She gave it some quick tugs and then gazed up at me, pleading. "But I so wish you'd let me lick you first, Master deserves for me to service him. And I so wish you'd let me wrap my eager mouth around your beautiful cock... Please may I?" She batted her eyes. Her hips were flexing again. My goodness this girl was perfect.
"If you must, my sweet plaything, I cannot deny your wishes." I pushed her to her knees, so I now towered over my sweet young plaything. She gazed up at my face, my cock throbbing above hers.
Just as she'd been trained, she started by paying tribute to my testicles. She kissed them sweetly, knowing how much I love a naive, obedient girlish kiss. Then her mouth opened slightly to reveal her hungry tongue, again only gently beginning. Finally her mouth opened wide and she gave my balls long, spit-coating sucks and licks as she cooed lustily. Giving a few pointed prodding licks behind my balls, she whimpered, reaching up to grab my throbbing shaft to steer it toward her salivating mouth.
"How is our hot girlfriend doing outside, Master," Anna asked just as her mouth clutched onto the end of my cock. She suckled hungrily as I looked up.
Anna was on her knees, her feet out behind her, her legs spread, her little skirt askew, showing lots of delicious thigh.
Sara sat on a little bench outside, just across from me, absently parting her perfect legs. Her friend Pam had gone, and Sara was now alone, lost in her books. I glimpsed her little cheer shorts, which were made to be seen, of course, though the thought that these young ladies wore cheer panties that were made to be visible is somehow very, very hot. It is like permission to look at panties in a sexual way.
"Mmm, I can see sweet Sara's little cheer shorts, my plaything, they are shiny gold...."
Anna moaned, "Oh, master, I'm glad you have a chance to see your girl's panties. I know how much you enjoy that...." She was gripping my cock in her hand and sucking on the head. She licked and sucked hungrily. She took my left testicle into her warm inviting mouth and rolled it around in there, then took the other and did the same. She gave my balls a long, lovely lick or three.
I grabbed Anna's short hair by the sides of her head and brought her pretty mouth to my cock.
She whimpered, excited. "I'm gonna fuck your hot little mouth, pretty girl. You want your mouth fucked, baby?"
