A very Convenient store

You walked with her down the street and a gust of wind flipped her skirt up, letting you see that she was wearing that string thong. From behind you also spotted a small mark on the side of her neck where your mom seems to have left a hickey. You knew exactly what it was but you do want to know what she would give as a reason so you ask "What's that mark on your neck?"

Very quickly her hand slaps the side of her neck covering it, while letting out a soft "Ahh!" you can tell you weren't supposed to hear that it was very quiet. She slowed her pace so she was walking beside you the mark on the other side of her from you so you wont be able to see it. It took a long moment for her to speak but not long enough for you to ask her about it again. "It's just... a bruise I got earlier, I tripped"

You swear she was just about to say she didn't know but it would have been a weak argument.

It didn't take long for the two of you to arrive at the store. When you entered your Girlfriend sped away from you towards the condoms, following after her you notice the cashier was one of your classmates from the same year even.

Her name was Katie she was one of the known lesbians at school, you've personally seen her with multiple girlfriends at once all sitting together and taking turns giving kisses. You can only imagine the stuff that happens when they aren't in public. She wasn't that close with you but she was good friends with Ellie. Her current line of sight was towards your Girlfriend who was bending over looking at the shelves, the string that was her underwear was doing nothing for decency it was even trying to be more indecent as it was pushed to rolled to the side not even staying in place.

You quickly stood in her line of sight blocking the view, you made a point of not looking at her but you swear she let out an irritated click of her tongue. The knowledge of your Girlfriend inadvertently giving a show to the cashier caused you to feel excited. She was currently reaching out and pulls a box off the shelf it was box of the largest sized condoms you are going to have to move and let the cashier get her eyeful of your Girlfriends pussy.

You move to the side and speak up "How about these ones?" You are pointing to a box of normal sized ones that would definitely be the correct size for you. "They should be the right size"

Your Girlfriend was hesitating and before she could come up with a reason to get the largest size, the cashier speaks up from behind you. With your back turned to her you didn't see her approach but she was definitely close enough to hear what you said. While walking to the other side of your Girlfriend she says. "Yeah, getting a correct size is important. It could be dangerous as it could break and you'll end up stuffed full of cum with no protection" The wording was a bit weird and very forward but you did note that your Girlfriends hands tightened on the box seems the words made her double down on the 'correct' size.

Your Girlfriend glances at you with a slight panic in her eyes, but it goes away when she looks at you as the eyes start to cloud with a bit of lust. Katie makes a motion with her hand that catches your attention and manages to remove the box of extra large condoms from her hands. How'd she even do that? Those hands had a **** grip on them. Your Girlfriend then speaks up "Hello Katie, I see you got a new job" She turns her head away from you and looks to the other side as she addresses her friend.

Their conversation was fairly short but Ellie's actions were slow and clumsy almost in a daze she weakly grasps the box of normal sized condoms you had pointed out that was stealthily placed in her hands. She wasn't even looking at the box in her hands as if she had forgotten about them. Then the three of you are done choosing condoms and after a quick whisper between them Ellie says "John, mind getting something for your mom? I'm sure she would like something I'll get us some drinks." Very quickly the two of them turn around walking to the other side of the store where the drinks are.

You couldn't decide what to get for your mom, but you basically forgot about it when you were looking at the snacks near the register. The small TV that showed the cameras in the store. There was only two cameras, one for the register and one for the rest of the store. But the camera was by the drinks so you get a clear view of Katie pulling your Girlfriend by the hair as she crawled on all fours. Your Girlfriend's shirt was unbuttoned and her breasts were hanging down. You watched as they walked closer to the camera Katie using your Girlfriends hair as a leash, they stopped as Katie sat on a counter and tapped on her thigh.

Looking over the shelves you spot the head of bright red hair leaning against the wall. You've no idea how she managed to convince your Girlfriend to do this but you note that she was currently not using her hands as she tries to get the pants open. It seems Katie was getting impatient as she undoes her pants and lets her resume, you were surprised when a cock popped out of those pants. Even more surprised at the size, while not at your mom's size it was still much larger than yours. The cock easily disappeared down your Girlfriends throat.

How does your Girlfriend easily attract all the Futa's? But at least you know why she had so many girlfriends at school. You realize that you couldn't really do anything other than wait, it took a while but it seems this was intentional as she looked at her watch and then pulls your Girlfriend off her cock and releases her cum all over your Girlfriend the cum splashing over her face down between and over her breasts.

Your Girlfriend was still shoveling cum into her mouth when she approached, there was none left on her face but her shirt was closed again you could still see some ropes of cum in her cleavage as she stops trying t o get the cum off once she sees you.

Neither of them brought up the fact that they didn't get any drinks and that you didn't get any snacks. While checking out Ellie realizes she got the wrong size condom as Katie says "One box of normal sized condoms" Ellie's face looked troubled as she asked for payment. That's when you notice you didn't get any money from your mom to buy them, you were going to pay for your mom's condoms to use on your Girlfriend.
