A bright flower print sun dress

Ding dong! "Come in." You welcome. Tammy steps in wearing a beautiful sun dress, low cut in front with wide shoulder straps and hem falling just below knee level. "Whoa, you look nice!" You compliment. "Thanks. I made a quick stop at the pharmacy on the way over to pick this up for you because I know you're going to need a supply." She's holding a plastic store bag but hurriedly asks, "Ok where are these new panties?"

"Follow me Madame." Heading into your room. "No woman's touch in this decor." Tammy observes. Then she pick's the numbered panty liner off your bed, walks over to the closet, peels the paper off the back exposing the adhesive band and sticks it to the back wall of the closet. "So you don't lose my number, Patty. Now for the business at hand." She pulls a rather femmy decorated package out of the store bag and opens it. A 100 count package of contoured panty liners. "OK, hand me a panty." You hand her the one on top of the pile. A beige colored cheeky boy short with a wide lace waistband. She takes it and says, "Here's how you do this. As you know, pussies are a source of moisture. These will save you the embarrassment of wet spots on your pants which will cause adverse thoughts about you at work or anywhere else in public. By the looks of your boxer briefs last night, you are more than capable of a soak through so pay attention." She holds the panty by the gore. (That's the name of the part that is the cotton liner in the crotch.) "You see the back seam right here?." She peels a liner and places the back end right on the back seam of the panty and presses back to front into the cotton lining of the panty. This will ensure perfect positioning of the liner to protect your pants and dignity."

"Now. Off with that robe and try these on." She ordered throwing you the recently lined panty which you put on without hesitation. "Wow! They feel...they feel... they feel absolutely amazing!" You stammer.

"Next lesson, Patty." Tammy instructs. "While trying on panties, you wear panties to keep your pussy secretions out of the tried on panty in case you don't like it, then it wont be soiled. Ok. On with the show."

"That all makes perfect sense. "You say. "Thank you for the lesson!" As you try on at least a dozen of various styles, bikini, hipster, high cut, tanga and thong, each time giving Tammy a twirl to which she showed her appreciation with clapping and smiling but by the last one she pulled her sun dress off over her head exposing her naked body beneath.

"Come here, Patty you fellow lesbian," and she pushes you back onto the bed just after you got one foot out of the panty you wore for the try on session. Right away she took to licking your clit and you struggled to reposition to be able to simultaneously return the favor. Much licking, slopping and groaning accompanied by heavy breathing ensued until you both collapsed in ecstasy! You drifted to sleep and barely noticed Tammy get up and head into your bathroom taking the store bag with the package of panty liners with her.

Once inside she pulls a blue X-Change basic pill out of the bag and downs it swallowing a slurp from the faucet to chase it. Within minutes Tammy is Timmy, a handsome dude with much the same build as Patrick but with a 9 inch throbbing hard on!

Back to bed continuing the oral **** on Patrick's newly acquired female part, Timmy was prepping you. You begin to buck your hips humping into Timmy's tongue. This was Timmy's que that Patty's pussy was ready. He moved up and without warning rammed his hot meat balls deep into Patty causing your eyes to open wide, your chin to drop and your lips form the O shape! You wanted to find out who was fucking you but couldn't speak as Timmy's relentless long stroking had you totally and blissfully speechless! This went on for a half hour or so before Timmy tensed and exploded Patty full of cum causing you to to verbally moan, your head back, your hands pulling Timmy's ass in as far as possible while you continued humping until the last spurt spasm.

After the breathing sort of normalized, "I was Tammy but will be Timmy for a few more hours. While at the pharmacy this morning I picked up a blue X-Change basic to try fucking you with a real dick and I have to say its way better than the strap on." Tammy, I mean Timmy explained.

You got up and scurried into the bathroom to sit on the toilet and drip out a little before wiping and returning to put back on the lined boy shorts, crawl back into bed and sleep off Timmy's presence. Never in your life had sex been this good!
