The salesman said "Ah trying out the pocket bra are you?"
Having put on the bra you said "well it's nice and my breasts aren't jiggling like crazy... why is it called the pocket bra? I don't see any pockets."
The salesman grinned and said "Well have you ever seen an anime where a big breasted woman takes thing out of her breasts?"
You said "No, I don't really watch that sort of stuff..."
The salesman chuckled and said "Eh one of the guys in research and development is really into that stuff... that said it gave us an interesting product. Basically it allows you to place things in between your breasts like a pocket." He took out a pen and said go ahead try it.
You took the pen and then smooshed it inbetween your breasts and while your breasts got a little bigger you couldn't really tell. You then took out the pen and said "So what? It's a pen most women with cleavage probably could put a small pen inbetween their breasts."
The salesman said "Oh sure a small pen probably..." he then went behind the display and then pulled out a giant version of the same pen about the size of a spear and then said "But how about a giant pen?"
You chuckled and said "You're... not going to try to..."
The salesman went to you and said "Come on trust me... I'm just going to put it inbetween your breasts, i'm not going to try to skewer you." He then started to shove it inbetween your cleavage. You were expecting the giant pen to come down through the bottom but as it was going into your cleavage it was not coming out the bottom. Instead your breasts seemed to grow and get heavier. After the pen was shoved deep into your cleavage your B-cups had been expanded into H-cups. The salesman said "I suppose another name we give it is The Ultimate Stuffer since all that mass has to go somewhere and... well let's just say the breasts is easy... Now then let me help get that pen out of your breasts."
You were surprised as the salesman pulled your cleavage open and then jumped into your breasts. You're breasts now were as big as that person and you could feel him squirming in your breasts so you said "Please stop screwing around in my breasts."
The salesman pushed his head up and said "Just getting the pen out... Now then..." He jumped out of your breasts quickly with your pen making them shrink back into their normal B-cups. You patted your chest surprised that they shrank really quickly and with no side effects. The salesman said "So you want one? We can make your suit have the same effect as the bra while your in the park."
You thought and said "Yeah I'll get the bra... Actually can I get like 3?"
The salesman scanned your suit and then said "Alright, you got 3 bras and don't worry about size... they are one size fits all... kinda have to be since they have to stretch basically for the largest of sizes..."
You asked "Can I get a bag for-"
The salesman giggled and said "Why would you need a bag, your suit acts as the bra now so... why not test it out?"
You shoved the bras in your breasts making them C-cups and then said "Huh, that's interesting. Does this work on men too?"
The salesman said "it works for men, women, children, pets... heck I suppose if you used it as a jockstrap or something it would make balls bigger."
You thought about how you wanted it to work and then decided you wanted a way to change into a girl at will when you got out of the park. Looking around you found...
