We exit the shop with two dozen bags and decide to go back to the van to drop them before continuing our shopping expedition. After doing so, we go back inside and start looking around until I find our next target. A lingerie shop. We passed a few bigger ones so far, but I decided on the smallest for a few simple reasons; less customers, less employees, usually easier to pay your way out of a pinch.
We head inside and start browsing. At this hour, only a few women are around shopping, and while I get a few nasty looks, in the end they decide to ignore me. Along with Tina we make our way through a sea of panties and bras, choosing this and that as we progress. Tina's choices at the beginning are all simple single-color underwear, without lace or decorations, until I grab her and bring her to a corner and explain to her,
"Honey, today, we are not choosing underwear for you to simply wear, we are choosing underwear that will make daddy happy to see you wear. If I see you in your lingerie and yet I do not touch you or take you on the spot, then it means that that underwear is not good for you".
Tina mulls my words for a few seconds, before smiling,
"Okay daddy, Tina now understands".
We start again our trek in the jungle of lace, this time Tina is bolder in her choices, nonetheless, for every piece of lingerie she picks, I pick 5 kinky ones. After twenty minutes, our selections are done and we are ready to move to the changing room. To my disappointment, the so-called changing room is a simple partitioned stall with a saloon type door. A few women are hanging around there to try the merchandise already. This in not good for me, as the changing room is in full view of the rest of the store, and the door does not cover heads and feet. Thankfully I already considered my options before entering and noticed a door behind the cashier. I moved to talk to her, bringing Tina along with me. When she sees me, she sports a dubious expression, however upon realizing the amount of merch both I and Tina are holding in our hands, it changes to a smile, probably thinking of her sales commission.
"Hello, I was hoping you could help us", I say while smiling politely.
"Of course, Sir, how can I assist you"?
"You see, my daughter liked a lot of the lingerie she found in your store, so we will probably buy most of it. Of course, she would like to try it first. However, not only the changing room is crowded, but my daughter is rather shy". Upon hearing my words, Tina drops her head a bit and half hide behind me. Good kitty, I'll pet you a lot later.
Continuing, I slide two one hundred bills on the desk,
"I was hoping, you could loan us a private space, perhaps an office, for a little bit", my sincere smile never leaves my face.
The cashier looks at me, looks at the money, then looks at Tina, before looking at me again,
"Well, it is against our policy, but if it is to help a shy customer, I suppose I could loan you a space. Let me bring you there, dear". The last part was aimed at Tina, but there is no way that I'll get cockblocked here.
"Actually, I would prefer to accompany my daughter, as I said, she is shy around strangers". Two more bills slip on the desk.
"Of course, I can move away a bit and you can ask her yourself. I understand how all this sounds after all".
My words seem to do the trick. She looks at us once again, before sighing and pocketing the money.
"As long as she does not mind, it is none of my business. Come with me". Thus, for the price of four hundred bucks, we got a private changing room. Well, actually is a storage room with a couch, a table, and a full-size mirror, squeezed in an empty corner; the door locks however, and the cashier promised that she will keep the rest of the employees out until we are done.
After she leaves, I close the door and then move to the couch and sit down.
"okay babygirl, time to impress daddy".
Tina loses her clothes and starts trying the lingerie one by one. With every change, my dick rises an inch more, until she tries a special set chosen by me, a black almost transparent set, adorned by lace. The sexiest part is that there are vertical slits positioned strategically over the nipples, and a similar slit exactly on top of her vagina. The back of her panties is a simple string that disappears between her cheeks.
Unable to stand it, I stand up, loose my pants and underwear in a fell swoop, then grab her and sit down again dragging her with me, her back to my chest, my cock nestled between her buttcheeks. My hands move up, one, to her face, to turn her for a kiss, the other to her bra, where my fingers infiltrate the slit in the fabric to pinch her nipple. I break the kiss for a second and tell her to move her ass, before plunging with my tongue in her hot mouth again. Tina obeys joyously, and start to grinds her ass on my erection, which by now has reached new height.
Finally, following a whisper of mine in her ear, Tina raises her ass a bit and reaches back with her hands. One hand goes to move the slit of her panties to the side, while the other, guide my cock to her pussy. She starts rubbing my cockhead on her fat lips, juices already flowing from her vagina and soaking my dick, until it is fully coated. Then she moves the string separating her asscheeks to the side, and brings my cock to her asshole. She rubs the head on and around the hole while moaning, and then she lowers herself a bit, until half of my glans is inside her ass, before finally dropping all the way down, welcoming my cock in her innards all the way to the root.
"Hnnnng… daddy… I wanted this all day… please daddy, use my ass…".
To her lewd comments, I answer,
"Honey, move yourself on daddy's cock. Show daddy how much you like it".
Tina moans a 'yes daddy", and starts moving up and down as deep and as fast as she can.
I enjoy the feeling of the teenage asshole around my cock. No matter how many times we do this, it is amazing how much it manages to squeeze me. Little by little I feel the resistance against my cockhead reduce, as if her colon is straightening itself to accommodate my length, until I am so deep inside her that I feel regret that I can not fit my balls in there too. Tina is exhausted from the movements and has stopped, her body drooped on top of mine, so I say,
"Good girl, honey, you tried your best, so daddy will reward you".
I grab her hips with both hands and start thrusting upward strongly, causing my cock to pierce all the way deep in her ass, before sliding almost completely out of her sphincter, only for the next thrust to nail it again inside her all the way. I grunt as I move, and tina moans and cries "Daddyy…. daddy…". Finally, my balls cannot endure more and start filling her ass with my cum while I shout,
"Daddy is cumming, honey. Cum with daddy".
Tina's body arches in spasms, and while yelling, "Daddyyy. Tina is cumming…. Tina is cumming!", reaches climax and soaks the couch in her juices. We lay spent for a minute to regain her breath, before Tina stands up, causing my now semi-flaccid dick to plop out of her ass, and kneels in front of me to lovingly clean my dick with her mouth…
We stay in there for two hours, trying the lingerie and having fun, before moving to the cashier to pay for our choices. Our little trip for lingerie costed me a little more than two grand, including the four hundred that I gave the cashier in the beginning, and the extra two hundred I gave her while leaving to have the couch cleaned. Totally worth it.
