They went to a slumber party, I stayed home

When they were ready, Sarah was wearing some delightfully tight jeans and a top that both revealed her midriff and had a great cleavage. Zoe, as usual, was wearing a dress. When I glanced at her, I couldn't help but take a brief peek at her cleavage, as seeing her in a bra was so good it made me feel guilty.

"It's a slumber party, and we'll get changed when we get there. But how do we look?" Sarah asked.

"Wonderful! You're both beautiful!"

"Yeah?" She said with a little giggle.

"Yes, you're gorgeous" Zoe told her softly and a little shyly. "I love the way your jeans define her curves more. Your ass looks even bigger with them." As she said that, she gently caressed my girlfriend's ass. I mean, she was definitely right, but it was still strange.

"Woah, thank you, baby!" Sarah replied.

"And your top is so lovely. I love how it pushes your boobs together and makes them jigglier." Zoe continued as she gave my girlfriend's breasts a light tap on their bottom, making them jiggle like jello.

"Haha, thank you!" Sarah smiled at me. "What do you think, Liam?"

"Huh?"

"Do you agree with what Zoe said?"

"I... Yes! Absolutely."

Sarah looked so happy to be complimented by her girlfriend and me.

"You also look amazing, Zoe!" Sarah said. "Right, Liam? Don't you love how juicy her breasts look?" She fondle them gently, making Zoe blush a little. I nodded in agreement.

They had a brief friendly french-kissing session as they now usually did while they were waiting for their taxi and I was watching TV. I don't know why, but I started accepting —and even enjoying — it when they did that. Especially because of Sarah's very loving attitude towards me. She was still a very caring girlfriend, so I know she wasn't leaving me for Zoe, or anything like that. They were just friends! And they were free to express their appreciation. I grew more and more comfortable with those affection displays.

Soon after, their taxi arrived. Sarah kissed me goodbye while Zoe hugged her by the hips and gently grabbed her ass. Then they both waved goodbye and left.

I was so happy Sarah could socialize with her girlfriends the way she couldn't when she was younger. I was so proud to have an amazing girlfriend!

After they left, I started watching a movie, and forty minutes later, I got a couple messages. One was from Zoe, one from Sarah.

Zoe » You are such a good boyfriend, and your girlfriend is amazing, Liam. I'm sending you something for dinner, so you don't feel lonely tonight!

Zoe was so nice to me. No wonder why Sarah loved her so much.

Sarah ❤️ » I'm gonna have such a good time with my girlfriends!

With her text, Sarah also sent a photo. It looked... Familiar. Maybe a meme or something I've seen before, but I couldn't quite put my finger on it. In the photo, Sarah was sitting cross-legged on a bit sofa, and behind the sofa, there was a group of girls around her age. There were around seven girls, including Monica. I supposed Zoe was the one who took the photo. All the girls were smiling and looking at Sarah, and they all seemed really excited. Sarah was looking at the camera directly, smiling adorably. They were all wearing very sexy lingerie —I mean pajamas, as Zoe said—, in different colors. Sarah's was white.

I felt a little guilty to be looking at a group of such beautiful women. They all had amazing curves, although they had different body types. But it was my own girlfriend who'd sent it, so there was nothing wrong if I kept the photo, right? I started wondering if she would also kiss and touch those friends the way she did with Zoe.

» Have a fun night, Sarah!

I replied. Several minutes later, there was a knock on the door. It was a girl delivering a pizza for me, from Zoe! She definitely treated us so well!

"Hey, is the redhead around?" The delivery girl told me as she handed me the box. She was trying to look past me into the apartment.

"Huh? Oh, no, she went out."

"Bummer. She... Uh... She seems lots of fun. Are you her brother?"

"What? No, I'm her boyfriend."

"Oooh... Nice. You've got a gorgeous girl, man. You're so cool." She said with a smirk as she left.

I didn't mind that too much. I had a whole pizza and watched a movie, and went to bed early while my girlfriend had a fun night with her girlfriends.
