Sod it, shove your dick in!

You decide to take a bold move and shove your dick in the hole, hoping desperately that Jo doesn't decide to attack the invader. Your cock grows rapidly as you wrestle your flies open and pull it out, but you pump it a few times to bring it to a fully erect state. You step up to the wall, take a deep breath, then thrust your dick into the hole.

For a few seconds, nothing happens, and you wonder if Jo has even noticed it. However, suddenly you feel a hand wrap round your shaft. You look down and see a shadow from under the cubicle wall, and sigh as the hand starts to wank you off. You pres up against the cubicle wall to push you dick in as far as it will go, and are rewarded by a mouth pursing itself around the end of your cock.

The mouth sucks hungrily, and you picture Jo crouched in her lingerie sucking an unknown dick off. You can hear the sound of heavy breathing in the next cubicle and a woman's voice moan quietly, muffled by your dick. You presume that Jo is fingering her pussy next door, and this causes you to become more aroused.

The hand starts pumping your cock while you feel a tongue licking your end, occasionally feeling the mouth plunging down to the base of your cock and back up again. Each time this happens, you moan, but quietly, so as not to get found out. You hear moans again, and you can make out a very quiet slapping noise, like soapy hands being rubbed together, which you can only guess to be Jo rapidly fingering her wet cunt.

The mouth begins moving up and down faster now, moaning intermittently. You can feel yourself reaching a climax. Suddenly you let fly, your cum squirting deep into the back of the throat on the other side of the cubicle. You immediately squirt again, just as the first load is swallowed. She does not stop there, though, and continues to suck your dick fast, pulling every drop out and swallowing it all. Finally, however, she stops, and you pull your dick back through the hole.

You do up your flies again, grab the shirt and open the curtains. You stop dead as you see Jo standing there, fully dressed, and looking around.

"There you are, I was wondering where you had got to," she says, as she turns to see you. "You buying that shirt?"

You look back at the changing rooms and realise that in your haste to see Jo naked, you didn't realise that the glory hole was on the wrong side of your cubicle! As you stare, you see the curtain of the changing room that you DID stick your dick into open. Out of it comes a young sales assistant, recognisable by her uniform of a navy blue skirt (which she is rearranging) and matching jacket, white blouse and name badge, which reads "Claire". She is about 18, quite short, with her dark hair tied in a loose bun. She starts to wipe something from the cormer of her mouth, looks at you and grins, shyly.

"John?" says Jo, snapping you out of your trance. "Are you?"

You stare at Jo, a little dazed. "What?" you ask. "Oh, the shirt, no, it didn't fit me."

You walk back to Claire with the shirt and hand it to her. "Thanks," you whisper.

"No, thank YOU! I enjoyed it!" she whispers back, before walking away.

"I'm not buying that lingerie, it felt uncomfortable, so we will have to look some more," says Jo. "Maybe I'll look in the Nightwear department for something."

You are a little disappointed that you didn't see her in the set, and consider asking her to model them again. Then again, maybe you could pick out something better.
