It was noon as Dipper waited outside for Pacifica dressed in an adult version of the outfit except with jean. His waiting didn't last long as Pacifica showed up in her dress ready to shop.

"hey Dipper thanks for coming."

"no problem."

The two headed into the mall side by side looking a round before Pacifica took the lead taking them to the new store that opened last week.

"you brought me to a lingerie store."

"hey, I need some new thongs & bras…this ass may be amazing, but you be surprise how fast it can it can wear down my underwear." She said slapping

"no, I would not." He said watching it jiggle

"very funny…beside this place is for girls with my figure"

"I don't see why women torture yourselves with your clothing."

"well there lies the tragedy."

Heading inside they looked around Pacifica seeing the wide selection they had for girls like her made her happy.

"this place is like thong heaven."

"wow she really likes it here but why bring me."

Suddenly one of the associates walked up to them with a happy if not a little creepy expression.

"good afternoon welcome to Thicc how may I help you."

"yes, I picked out a few styles I want to try on, is one of the changing room open for use?"

"I believe room two is available."

"good I'll take that one."

"ok & is he with you?"

"yes."

"sir please come with me."

"wait where am I going."

"males who accompany females are asked to wait in a room in the back."

Taking Dipper to the back of the store he was led into a room with a recliner facing a draped wall.

"please take your seat,"

Confused with the request Dipper decided to follow with the instruction, sitting down & nestling in to the chair.

"are you comfortable."

"I guess so."

Dipper was caught off guard as restraints popped out of nowhere locking his arms & legs to the chair,

"what the hell is this!"

"precaution sir they will unlock when everything is done,"

"what are you talking about."

"have fun & no funny business." Said the associate as she left

Still struggling to move Dipper watched as the drapes began to open revealing Pacifica was on the other side now dressed in a robe.

"Pacifica what the hell is going on?"

"yeah probably should have warned you about this."

"about what…what is all this?"

"basically, it's store policy."

"if you knew then why bring me here."

"because I needed your opinion."

"on what?"

"on this."

Pacifica proceeded to remove her robe standing in front of him in a black thong with a matching bra. Dipper face turned bright red as his friend walked closer to him allowing him a better look at her sexy body.

"Pacifica?"

"when a girl come in here with a male they are allowed the option to model their selections for him to make sure no funny business…the male is restrained."

"I see…why am I here again" he said

"I needed a guy's opinion on these…now be honest do these look good on me?"

"um yes…"

"ok what about the bra does make look bustier…does it is make my boobs look unnatural." She asked as she pushed out her tits bringing them very close to his face

"yes & no…this why is she doing this to me & why am I so turned on." He said & thought

"that's good…wait the thong."

"what about it?"

Turning around Pacifica bent over sticking her ass up & at Dipper giving him an up-close view of her jiggling ass. Dipper was speechless his friend was basically shoving her sexy ass in his face he arousal was rising causing him to try & resist his growing erection.

"does it make my butt look bigger?"

"I…."

"don't hold back you can tell me I won't get mad." She said swaying her ass

"fine then it does."

"good also does it look like it goes up my ass too much."

Suddenly Pacifica reached behind herself grabbing a handful of her cheeks spreading them letting him see everything. Dipper let out a gasp at what was happening he couldn't believe that Pacifica was doing this however the thong somehow covered her up her bits.

"why are you doing this?"

"I already told you I needed your opinion…now does it."

"it does not ok."

"so over all you like them."

"yes it looks great on you."

"That's great to here I'll this pair."

As Pacifica was about was about to leave she suddenly fell backwards landing on Dipper's lap.

"oh, Dipper I'm sorry I didn't mean to…OH!" she yelps

Dipper tried his hardest, but he couldn't hold it anymore as a large bulge in his pants form pushing up against Pacifica's ass.

"Dipper is that what I think it is." She asked rubbing against it

"sorry I couldn't help it."

Pacifica began to playfully grind her ass against his crotch making the bulge his pants even bigger.

"well it couldn't be helped."

"what?

"I'm modeling underwear it's pretty natural for you to react this way."

"you're not mad."

"of course, not if & this pair make you react like this I can't wait to see what the others will do."

"others?"

"well duh I said way buy more than one."

Hopping off Pacifica walked off back behind the drapes as the closed behind her, Dipper could only watch as they closed.

"oh no these are really special."

"huh."

"I can't wait for you to see me in these."

Sticking her hand out Pacifica showed a thong with string so thin with hearts placed in different places.

"oh god."

Later that day…

After modeling 10 different pairs Pacifica was finally done having chosen her selections based on Dipper's reaction to each one she was happy with how things had turn out. Dipper was not he was still embarrassed about Pacifica & her sexy underwear; the problem was worse because his erection was still there & had to use his vest sitting it on his lap to cover it.

"hey Dipper, I'm back."

Looking up he noticed Pacifica holding two large cups of pit cola, handing one to him she sat next to him as they both began to drink.

"wow you're still hard."

"you know this is your fault."

"mine all I wanted was your opinion on some underwear I needed…not my fault you're horny."

"I'm not horny."

"that erection you're trying to hide says different."

"hey if you hadn't fell on me it wouldn't have gotten this bad."

"hey that was an accident."

"didn't feel like it when you were grinding me."

"can you blame me it was the closest I got to the real thing."

The two both began to take more sips of their drink for a moment a brief there was silence between them before Pacifica began to talk again...

"Dipper I want to ask you."

"what is it?"

"I want to have sex with you."

"WHAT!?" spitting out some soda

"keep your voice dork."

"Pacifica you know what you're asking."

"yes…look I did some thinking from what you said last night about not trying to get into another relationship so soon & just wanted to get laid."

"yeah."

"I realized I wanted that too but I'm not just going to spread my legs for some random guy then I realized who better to be my official first than you."

"but we're just friend don't you that would be a little awkward."

"haven't you ever heard of friends with benefits?"

"yes & from that I've heard it nearly always ends badly."

"it won't for us we're not looking for romance… just to turn in our V-Cards"

"is this why you brought me in the first place?"

"partly…I really did need the new underwear, but I also wanted test just how attractive you found me before I make this proposal."

"ok."

"beside you've seen what I have to offer & I felt yours I say we go for it…"

"I see & what happen if we suddenly find someone?"

"we stop just like that."

Dipper couldn't help but be a little skeptical about this plan, the thought of being with Pacifica in this way never crossed his mind but after today it would be impossible for him to see her as just a friend.

"so, what do you say Dipper what to plant your pine tree in the northwest?" She asked seductively as she place his hand on his lap.

"I…I"

Dipper didn't say anything, but his dick did the talking as is started to twitch & Pacifica began to feel it under despite the what was between them. This excited Pacifica as she gave Dipper a kiss on the lips nearly causing him to drop his drink.

"I knew you'd love this idea this is going to be great."

"Pacifica I…"

"good so I'll head home & get ready then I'll come by your place late tonight."

"I…"

"you don't mind if I bring somethings to stay then night do I."

"I…"

"of course, you don't…you're the best sex friend a girl could ask for"

"I…"

Pacifica cut Dipper off again giving him another kiss before grabbing her things & rushing off.

"thanks again Dipper see you tonight & I'll be wearing one of these…but I won't tell which one." she said leaving

Dipper was confused at what just happened & the situation he suddenly got roped into all he could say was.

"I…"
