I followed Jenn up to her bedroom. I managed to get a glance of her pussy as she climbed the stairs to the main floor, then up to the the top level of her tri, where the bedrooms were. We sat on the bed together and Jenn kissed me quickly on the lips.

"Brad, I want you to do something a little unusual for me."

Jenn took a pale pink slip out of her closet and laid it on the bed next to me.

"Get undressed and put this on."

While this was a bit weird, I did sort of have a fascination for women's undergarments. I decided I would go through with whatever kinky plan Jenn had come up with, I just wouldn't let on how turned on I was by the thought of dressing up. The slip was a little bit too short, but that actually made it more sexy. I admired myself in the mirror, turning sideways. My cock became erect pitching the hemline of the slip out.

Jenn returned wearing a strap on, something I had heard about, but never seen. It was a translucent red colored dong about the size of my cock, but thankfully didn't have any detail to make it look any more penis-like.

My eyes were wide. This is not what I had been expecting. Jenn laughed.

"Come on Brad. It's my birthday. You're already Sarah's boyfriend. Just for today I want you to be my girlfriend."

Jenn was hot, I did kind of like having things stuck up my ass, and it was her birthday so I agreed.

She wrapped her arms around me and kissed me.

"You really do make a pretty girl. I'm going to call you Brenda. Is that OK?" Jenn kissed me again. She touched my face with her hand and ran her fingers through my hair. She tried to make a ponytail with her thumb and finger, but my hair wasn't quite long enough.

"Don't ever grow a mustache." she whispered.

Jenn continued to kiss me, touch my nipples and then ran her finger in a little circle around the wet head of my cock. It was more of a female motion than male.

"Do you need a little cleanse before we start?"

I thought a bit about my last few meals "That's probably a good idea."

Jenn took me by the hand and led me to the master bath.

"I'll just give you a few bulbs of plain water, is that OK?"

"Sure."

She opened the cabinet below the sink and pulled out a blue vinyl bulb syringe. It appeared cheap compared to the one that Sarah owned. Jenn filled the sink bowl and got a jar of petroleum jelly from the medicine cabinet.

"Just put one foot up on the toilet lid"

I stood there while Jenn lubed my anus, taking a few moments to enjoy having her finger inside me. She then submerged the syringe into the sink and filled it. The nozzle went in easily and she squeezed the water inside me. I opened the lid and passed the enema. We repeated this four times, the last two were clear water and Jenn said I was ready. Back in the bedroom, Jenn applied some more lube to my butt hole then handed me the jar and told me to put some on her dong. I stroked the Vaseline on the dong making sure it was well coated. It had several necked down sections that would shrink and stretch me as she stroked in and out. I climbed on the bed and got in the butt high position but Jenn grabbed me by my hips and laid me over on my back.

"I want to see your face when I make love to you Brenda. Have you done this before?"

"No" I replied.

"Oh this will be a special treat for us both. Are you ready to give it up for me?"

I looked up at Jenn and nodded my head yes. Jenn took a pillow from the bed and put it under my ass to make my hole more accessible, then began to work the dong into my sphincter. I winced a little as it first went in, but soon I was OK with it. Jenn laid on top of me and began thrusting the rubber dick up my ass a little harder.

"Do you like that? Hmmmm? Are you enjoying being my girl?" Jenn fucked on and I watched as her tits pulsed with each thrust.

"You're very lucky to be my little piece of ass, Brenda. Come on, take it. Take it like a whore." Jenn put her hands on my shoulders and held me down on the bed while she continued to thrust the rubber cock in and out of my ass. Jenn was an athlete and very strong. I admired the muscles in her arms and shoulders.

I felt humiliated, but sexy at the same time. I don't think I had ever had this feeling before. It felt good knowing I was giving Jenn pleasure. I remembered the rumors about Ms. Brock, and how most rational students passed them off as nonsense and there I was laying on my back wearing a slip as Ms. Brock the PE teacher fucked my ass with a strap-on. Life sure was weird. Surreal even.

The lube was beginning to wear off and Jenn said "Had enough? I'll let you off easy this time." Jenn accompanied me to the bathroom where she took off the strap-on and set it on the counter. I wiped the santorum off my butt hole with a piece of toilet paper.

Jenn looked at me and cocked an eyebrow. "All this activity has made me hot and sweaty. Would you like to take a shower with me girlfriend?"

"Oh yes!"

I ditched the slip on the bathroom floor and Jenn and I got into her bathtub and slid the glass door shut. Jenn turned on the water and smiled at me while we waited for it to come up to temperature. She held her foot under the faucet then pulled the plunger up to start the stream from the shower head. Jenn handed me a bottle of Wella Balsam then knelt in front of me. I poured some shampoo in my hand and began to massage it into her scalp, then letting it run down into her long blonde hair where I distributed it with my fingers. I got an excellent view of her large, wet breasts when Jenn tilted her head back to allow the shower to rinse it. We repeated with the conditioner. She playfully blipped the end of my dick with her finger tip while we waited for it to work. Jenn got up and handed me one of those gauzy woman scrub things and a bar of some translucent red soap. It was the same color as the dong that had recently been up my ass. I rubbed the soap then the scrubber on the untanned skin of Jenn's breasts as well as in between them and watched the water rinse the suds away.

"I can tell you really like my boobs. That makes a woman feel really special. Now get down on your knees."

I knelt down and Jenn turned around so I could wash her back and then down to her butt, soaping, scrubbing and rinsing. She spread he butt cheeks so I could wash her anus too. She turned around so her wet honey blond bush was just below eye level and spread her lips with two fingers.

"You're going to want to get that extra clean."

I soaped up Ms. Brock's pussy and rubbed it with my fingers as the scrubby thing would be to rough for the tender skin inside her slit. She smiled and thrust her pelvis outward to allow the water to run down her abdomen and rinse the lather out of her pubic hair and down the drain. Jenn exited the shower and I quickly washed my armpits, crotch and hair, an act that literally took less than a minute. I had to admit to myself that most of my time showering alone was still devoted to jerking off.

I dried off and went back into the bedroom where Jenn had already pulled the covers back.

"Come over here and sit next to me sweet heart." Jenn kissed me on the cheek, still treating me like a girl.

"I want you to go down on me and I want you do do it like a girlfriend. Some people think women eat pussy better than men because they have one, therefore they instinctively know what feels good. That's bullshit. Women know how to get other women off better because they pay attention and listen. You did well in square dancing, can you take instruction in cunnilingus?"

"I'll sure try."

Jenn drew her knees up and spread her legs slightly. I began to position myself so I could get my mouth down to her snatch.

"Wrong! The first thing you do is kiss me. Kiss me softly, like you love me for ever and ever."

I kissed Jenn on the mouth twice the second time she opened her mouth and allowed me to put my tongue in and wrapped her arms around me. After about a minute, she put her hand on top of my head and pushed gently.

"Kiss my neck and collar bones."

I complied and began kissing my way down her suntanned body, licking the tanned top of her breasts and then working my way to the white flesh.

"Easy with my nipples now. Just the tongue first."

I licked each of her brown nipples, trying to get them good and wet with saliva.

"Now go back and forth between them and roll the other one between your finger tips.

You do that so well, you may have been an actual woman in a past life"

While I had much enjoyed sucking on Sarah's glorious larger tits, I had done it because it made me feel warm and nurtured and horny. I really hadn't thought much about how she was receiving the stimulation. Jenn pushed me down further then took my hands and placed them back on her breasts. I kissed my way down her flat stomach.

"Put your tongue in my navel Brad." She had apparently screwed up and temporarily forgotten my girl name. I made wet circles inside her navel.

Jenn giggled. "I love that!"

Her hand was atop my head again and I kissed my way down into her pubic hair which smelled fresh and fruity like the shower soap.

Jenn gripped me firmly by the hair so I could only lick her with the tip of my tongue. Gradually she released the grip and I gave the inside of her pussy a sloppy wet kiss.She grabbed my hair again and pulled my head into position to lick her clit.

"Just go side to side"

I laid face down on the bed with my face buried in Jenn's snatch and rolled her nipples in my fingers. After a few minutes she began breathing heavily and moaning. "Yes. Fuck. Oh.... Come on. Lick. Fuck. Oh God yes."

Her powerful legs squished my face and she shouted FUCK! as she came.

While the language was quite inappropriate for an educator, I felt a certain pride in knowing that Jenn was satisfied as a result of my efforts.

Jenn kissed me and smiled. "Thanks for being my girlfriend Brad. I haven't done that for a long time."

I went into the bathroom and washed the remnants of Ms. Brock off my face. Jenn walked in and wiped her cunt clean with one swipe of a wet washcloth. My cock was at three-quarters staff.

"You've been a very good sport Brad. You deserve to get off before I send you home. I'm sure Sarah won't mind." Jenn returned to the bed and got in the butt high position.

"You gave me such a wonderful enema, I sure hate to let it go to waste. Do you want to get off in my ass?"

"I'd love that!"

I took the lube from the dresser and applied some to my cock, then rubbing some on her anus. I pushed the head of my cock into her asshole slowly. The opening felt very tight but the inside was loose and cavernous.

"That feels good Brad. Just fuck away. This is all about you now."

I knelt behind Jenn and fucked her ass, steadily while feeling my load build. I grunted as I came in five big contractions before tapering off.

"Oh baby, that makes me feel sooooo dirty. Did you like that Brad?"

"That was fantastic!" I said as my cock shrunk and was ejected from Jenn's ass.

"This is all top secret classified, understand?"

"Uh-huh"

"The Mary-Jos have our code of honor. Besides, no one would believe you anyway."

"Yeah, I know. I hardly believe it myself."

Jenn laughed then went into the bathroom, sat on the toilet and let out a splattery wet sounding fart that I assumed was my ejaculation beginning its journey out to sea. She wiped and flushed and I washed my penis with warm soapy water before dressing. The sun was setting when I found Jenn out on the deck smoking a cigarette. Jenn looked at me, the cigarette, then back at me again. "Not a word about this either. Not even to Sarah."

"No problem."

Jenn handed me a card in an unsealed envelope with "Sarah" hand written in girly script.

"This was fun Brad. I'm sure we'll get together again sometime, somehow."

I was going to bend over and kiss her, but sensed the time was over so instead grabbed her hand and said "Thanks, I had a great time. Happy birthday!"

I got into Sarah's car. I just had to read the card before leaving. It was a generic "Thank You" card with flowers on the front.

Inside it read:

Sarah, Thank you so much for the strap on! My favorite color!

Thank you especially for sending Brad/ Brenda to help me celebrate. I love her!

Best girlfriend ever! A++++++++

Love Jenn
