Kim becomes much closer to you

The days that followed could no longer be like before. You couldn't forget that your mother and sisters had huge dicks, and when you had the chance, you'd look at their crotch.

Your mother and Alice sometimes noticed your look, but you managed to hide it so they didn't suspect that you knew their secrets, but Kim gave a mischievous smile when she caught you.

In a moment when you were alone, you asked Kim how they managed to hide such huge dicks under their clothes so well. She replied that as long as their balls were well positioned and their dicks were flaccid it was easy to hide under a long skirt, the problem would be in case of an erection.

After almost a month that you had discovered the family secret, on a Saturday, you ended up staying alone with Kim at home while Alice went out with some friends and their mother worked.

You two were in the living room watching a sitcom when Kim's skirt started to lift.

"I'm horny. Would you like to join me?" Kim said

"Why not?" you said

Kim took off her skirt and underwear and you took off your pants and underwear, then you sat side by side on the couch, with her sitting to your left. You were about to start jerking off when she got your dick before you did.

"I have a better idea. What do you think we do a mutual masturbation?" Kim said

You accepted her proposal and took her hard cock, starting to caress it while she did the same with yours.

"I do not believe this? Kim, didn't Mom tell you not to tell him about your dick at all?" Alice, who had arrived home earlier than expected, said

"But I didn't tell him anything, it was Will who found out all by himself." Kim said

"Is it true what she says?" Alice asked you

"It's truth. I ended up watching her suck her own dick one night when I had to go to the bathroom and her bedroom door was ajar." you said

"And as you can see he's OK with that, he even likes to know that his sisters have huge dicks." Kim said

"This is very mean of you. Me doing everything to keep the secret and Will already knew everything. And you Kim, you could have told me that he found out." Alice said

"I'm so sorry, every time I thought of bringing it up with you, Mom was there. You know the trauma of the fight with Dad and the divorce after he found out she had a dick is huge. Even with Will accepting everything I think it will be a problem if she imagines that he could be close to knowing everything." Kim said

"I know, but this lie has to end at some point." Alice said

"And what are you doing here so early? I thought you were going to a party at Mike's house with your friends." you asked

"I was going to, but the idiot announced it on social media and his parents found out, so they **** him to cancel the party." Alice said

"He really is an idiot." Kim said

Alice said then "Well, now let's get to the most important part. If Will knows everything and likes the idea..." she let her skirt fall to her feet and then her panties, revealing her cock which was growing hard "...I believe there's room for one more to play." and she sat down to your right, taking your hand and placing it on her dick. Her cock was smaller than Kim's, but still impressive at 18 inches.

You then stroked your two sisters' cocks while Kim stroked your cock and Alice massaged your balls. Each of the girls reached her free hand under her own balls and played with her pussy.

As you stroke your sisters' cocks, they begin to moan, increasing the volume and intensity of their pulsating members as they approach their orgasms.

Kim was the first to get there, when she suddenly thrust her hips up and started to cum. You continued stroking Alice's cock in the meantime, and when your big sister's orgasm started to subside, it was your little sister's turn to come.

With her orgasm already over and while her sister was still coming, Kim reached down and placed her mouth on your cock. You were already at your limit and just for her to do that you came immediately, and she swallowed your cum.

Orgasms gone, with your cocks flaccid, you and your sisters put your clothes back on. They then told you to leave the house, just to make up an excuse to be out, as they didn't want your mother to arrive while they cleaned with you at home, as she would think that they took too many risks.
