The girls got to work on the sleepover. Tina called Anna. Anna replied "What a great idea to renew our friendship with a sleepover. Can I invite Tillie?"
"It would be nice to have her, too."
After hanging up Tina said "Tillie is not as big as Anna, but bigger than both of us and she got off at the same time as Anna. She is cute, too. I'll bet they are jerk buddies."
"I think we can wrangle two girls. One would have been easier, but the payoff with two is better, especially if they already do it with each other. I like it."
Tillie called to accept and thank Tina for the invitation.
Contact info was given to the moms.
Karen called Diane, Anna's mom. "I am Tina's mom. Anna is coming for a sleepover. I wanted you to know that I booted out my husband for the night, so no males in the house. Susan and Tillie are sleeping over. Susan's mom, Betty, will stay over, too. The girls are all under 21, but they are all over 18 and none of them are going to leave our property. I thought I might serve wine if that is okay. I have never done that at a sleepover before, but this is special. We will monitor consumption to keep everyone safe."
"Thanks for making this for women only. Some wine is fine. She will be in a safe space if she gets drunk. I am okay. Thanks for telling me."
"You are quite welcome to join us. We have a guest room you can use. I can double up with Sally's mom. If Susan stays over you might have to double up in a king bed."
"I will come meet you. I might take you up on joining the sleepover if I consume too much. Very generous of you."
The conversation with Susan, Tillie's mom, was nearly identical.
Anna and her mom, Diane, and Tillie and her mom, Susan, arrived at the 2:30 appointed time. All were dressed casually and somewhat conservatively in skirts and blouses as Diane and Susan did not know Betty and Karen. Sally, Tina, Betty, and Karen wore very casual skirts and button-down blouses with a small tease of their intent with no bras.
Introductions were made, snacks and wine served. The girls stayed with their mothers at first to show the moms they were upstanding young women. Both Anna and Tillie took after their mothers. Both had larger breasts than the mothers, but not by much. All four women had head-turning tits.
Anna pulled Tina and Sally aside and asked "My mom was wondering why you guys were not wearing bras."
Tina answered "No particular reason, but we don't have to worry about men ogling and, as you can see none of us are particularly large. Just a little more comfortable on a warm day. We want you to be comfortable. If you or your mom is not comfortable with bare tits, we will get bras."
"You know I am okay; we were nearly naked at Susan's." Anna talked to her mom and returned to ask "Is there somewhere to remove my bra? My mom, too?"
Tina jokingly answered "It's just us girls, you can do it right here."
"I would like to, and even stay topless, but we might shock some moms."
"Wouldn't that be nice? The topless part, not the shock. My mom would be surprised, okay."
"Naked?"
"Even better, even more shocking. Oh, well."
Karen took Diane to the guest room and Tina took Anna to the playroom.
While Anna removed her blouse and bra she remarked "Wow! You could have an orgy in here."
Tina gulped "I guess, so. That would change the meaning of 'playroom' and make this an interesting sleepover." Deciding to take advantage of the joke, Tina took off her blouse and threw it on the mattress. She followed with her panties.
"Why did you get nearly naked?"
"Just trying to be a good host. It seems if we are going to have an orgy buttons and elastic might interfere." She laughed hard and picked up her blouse.
"Cute. No need to prepare for an orgy."
"You are probably right, it might not happen and if it does, the blouse comes off quickly." Laughing.
Anna noted that Tina had still not dressed. Anna was interested in girls. She tended to look discreetly in the locker room and tended to dress slowly when other girls checked out her huge D-cup tits. Tina was looking and was not covering up. Anna was thinking that her orgy joke may have worked. She left her breasts out for Tina.
Tina was glad that Anna was okay with them lingering topless. "I hate to be rude, but I always knew you were large, but they have a nice shape, too. They really stand out on your chest without support. I wish I was larger."
"Don't be. These things get painful during periods, they hurt when I run, it is difficult to buy clothes, especially bras, and I get a lot of unwanted attention."
Tina turned her head and said "Oops, sorry."
"Not you. I wanted to get topless with you, remember? Mostly it is boys and men who just want to see them and feel me up. Once the novelty is gone, so are they."
"Okay, so no feeling you up." Joked Tina.
"Friends are okay. You are a friend and I know you are curious. Go ahead and feel me up. I really don't mind."
Tina used two hands on one tit and squeezed it and did the other. She rubbed the nipples as if by mistake. Anna took a short breath at the nipple rub. "I always figured large tits were soft. Yours are quite firm, pretty much like mine."
Anna was relieved. This was going well. She got felt up with a nipple rub and being invited to feel up Tina.
Since Tina was much smaller, avoiding the nipples was difficult, so Anna just felt her up like she wanted and tweaked the nipples.
Tina moaned said "I am ready for that orgy." With an unconvincing laugh.
"Sorry."
"Don't be. You can continue. Curiosity is fine. Wanted." To show she meant it, Tina tweaked Anna's nipples. Anna didn't protest. Tina looked at the nipples, opened her mouth, and started to lower her head and then stood up straight.
"Please."
Tina took a nipple in her mouth and Anna moaned. The door opened and Anna said "Oh my god" and covered her tits with her blouse. Tillie and Sally came in.
Tillie laughed. "You sure got going quickly." All four began to chuckle.
Tina said "You guys planned this ahead."
"Yes. I think you did, too."
"Yes."
"I kind of thought so. What I don't understand is why you ignored our invitation at the sleepover."
"I was afraid of getting on the L-List. I wanted to join you. So, you got off together as a plan?"
"Yes. I went first to lower inhibitions of girls who were considering it and Tillie joined 'reluctantly' trying to show them it was okay. It just didn't work."
"I sure lost out with you, but I got with Sally."
"But you guys got off separately."
"So, you pretended to sleep. We hooked up after you left. So, what is your story? You hanging together?"
"Kind of like you, we got together at a sleepover. I masturbated."
Tillie interrupted "First you teased everyone with your gorgeous tits. She got a few girls, including me, to get topless. It was great. Then you made some feel-up and masturbation jokes. I think everyone wanted to do the feel-up part, especially me, but, as usual, no takers. You masturbated after lights out. I did it, too, but, as usual, the others were afraid. They all did it later, covered up, of course. I teased them about it the next day to see if I could get someone to join me, but no one would admit it in front of the others. Anna asked to meet that afternoon. We masturbated ourselves silly. We have been hanging ever since."
"Just masturbation?"
"No."
"Are you a couple?"
"You could say that."
Anna butted in proudly saying "Yes, we are exclusive. I love Tillie."
Tillie smiled back and kissed her.
Tina informed them "So are we. Wow, all of our plans to seduce you are spoiled."
"Ours, too."
"Thank goodness; seduction can backfire. I am looking forward to sleeping with you. Do your moms know?"
Tillie answered "A bit. We are inseparable and my mom has caught an occasional kiss, but nothing extreme. Kisses that two close girlfriends might do. I think she fears we are lesbians but doesn't know how to ask."
"Are you?"
"Right now, sure, but we both like boys, so closeted bi is more accurate. How about your parents?"
"Yes, they know we are exclusive. We do kiss in front of them. They encourage us. We both like boys, too, but none for the foreseeable future."
"Anna, do your parents know?"
"My mom definitely knows, but my dad is probably like Tillie's parents; he does not know, but suspects."
Anna reminded them "I took off my panties in anticipation the orgy. Does anyone else want to cool off their hot parts?" The other three did also.
Tillie took off her bra revealing her slightly larger than C-cup tits. Sally removed her shirt. Tillie looked at her questioningly.
"I do not want miss the topless part. They all chuckled.
As Tillie started to put on her blouse, she noticed the others looking. She smiled at them and asked "Anyone want a taste?" Sally sucked one nipple for a few seconds.
Tina said "Let's go before they think we are having the orgy without them. I think it on my mom's agenda for later." More chuckles.
All four moms were a bit inebriated. None had a bra. Both of the guest moms were wearing white blouses and their large areolae were showing through. They had to be aware, but were doing nothing to diminish the attractive view.
Sally pulled the two host moms away. "Both of their moms have magnificent racks. Have you seen them bare?"
