On a picnic in the park with her friends

You finally made it out of Kim's womb, having to **** your way out as her vagina was mostly covered by your sister's balls pressed against it by a white cloth. You noticed that this fabric was her panties, and judging by the light coming through them from below, she was wearing a skirt.

Paying attention to the sound around you, you realized that she was in a square with a friend of hers that you already knew, Becca, and another one named Stacy, which she apparently had known for a short time.

Realizing that Kim was going to sit down at any moment, you thought it best to get out of where you were, so you circled her balls, being careful not to go off to the side and fall to the ground to be stepped on, and climbed up the front, past the her flaccid dicks. Taking advantage of the fact that the place seemed peaceful, you decided to hide there until she returned home.

Standing on one of Kim's cocks and draped over the top edge of her panties, you relaxed and, tired from your adventures, you fell asleep.

Not knowing how long you slept, you woke up with movement under your feet. Whatever was going on, something turned Kim on and her dicks were starting to get hard. Listening to their conversation, you realized that the picnic was over and you were in a store, where you accompanied Stacy while she tried on clothes to buy. You ended up being lifted up by Kim's upper cock, eventually sliding down it and coming to rest on its base, face to face with your sister's crotch.

"Do you think these clothes look good on me? I'm wanting to get a boyfriend and for that I need to be attractive." did you hear Stacy say

"You look great. If you animated Kim dressed like this, men will like it too." Becca said

"Why you say that? I don't intend to conquer girls." Stacy said

"It's just that you still don't know about Kim's little secret. But considering how far our friendship has progressed I think we can tell you now. Look closely enough at her that you will perceive a hint of this secret that is visible at this moment." Becca said

"So Becca knew about my sister's dicks and I being part of the family was left in the dark. This is not fair." you thought

After a few seconds of silence, you heard a sigh and Stacy saying "I did not expect it. Do you have an? So are you a guy?"

"I have twice as much of what you're thinking and no, I'm not a guy, I'm just a girl with some bonus." Kim said

"Can I touch it?" Stacy asked

"Of course you can." Kim said

You looked up and saw the fabric of the skirt wrap around your sister's dicks, and you knew it was her new friend feeling her cocks.

"Unbelievable, and they are huge." Stacy said

"Impressive isn't it? I felt the same as you when I found out. Now we can't leave with her like this. I'll help her, will you too?" Becca said

"If you don't mind." Stacy said

You felt Kim's dicks throb and a movement told her of course she started to walk, but it was a very short walk. Then your sister reached down and pulled her panties down to her knees, and when she got up again and lifted her skirt, you fell and landed in her panties, coming to rest in the wet smear of her vaginal juices.

The three girls were together in a dressing room that barely had room for them together. Becca was licking her lips and already bent down and put your sister's upper cock in her mouth, sucking it afterwards. Stacy took a while, looking startled by the size and unsure whether she would even be able to deal with Kim's tool, before venturing out to suck your sister's inferior cock.

Kim would move her hips to increase the stimulation on her dicks and her balls would swing like a pendulum, as did her panties hanging, where you held on to the fabric to keep from getting knocked off.

You were relieved when the moving stopped, a sign that Kim was cumming. Becca was able to handle the cum that came out of the cock in her mouth, but Stacy wasn't skilled at it and let the excess run down her chin and drip onto the floor.

"It was too much cum. I've never seen someone ejaculate so much." Stacy said

"Over time you get used to it." Becca said

After that Kim lowered her skirt and lifted her panties back, adjusting her already flaccid dicks. You ran away from her hand adjusting her balls, and then found yourself trapped between her buttocks, now unable to say what they said.
