They sleep in the bedroom, I sleep on the sofa

"We are all tired. It's been a great day, don't you think?" Sarah says with a smile and a lovely bounce of her breasts. "We should all go to bed."

"Yeah, you're right. I guess Zoe is staying..."

"In the bedroom, with me, of course."

"Huh? Why?"

"Liam" She sounded surprised I reacted like that. "She's our guest. She can't sleep on the couch. Also, she shouldn't sleep on that kind of places, because of her condition."

"But... It's our bed." I whispered. I didn't want Zoe to hear me and to feel bad. "It was supposed to be special for us."

"Our special night will come soon." Sarah sat on top of me, and ground a bit against my lap, feeling my erection and smiling. "And we'll share that bed the rest of our lives, hopefully. I think we can spare one week more. Remember Zoe is just a girlfriend. I'll be sleeping with her, but my heart is always with you." She took my face with her hands and kissed me.

The sleeping with her phrase sounded a bit weird, but there was nothing wrong with it. Sarah didn't mention anything about it, but I did feel a twitch in my cock when she said she'd be sleeping with her.

"Fine. I guess you're right. I'll take a quick shower before sleeping, then."

"Thank you, Liam! You're the best!" She kissed me again and got off me, leaving me with a hard cock under my pants. "Zoe, let's go to bed."

"Yes. Thank you for your hospitality, Liam." She seemed very happy. She stood up, turned around, and stretched with her back towards us, and Sarah prompted me to look at her ass. As Zoe stretched, her shorts got did too, and they tightened briefly against her body.

"Her ass is bigger than mine, Liam" Sarah whispered as Zoe walked to the bedroom. "Her hips are wider and her thighs are thicker. Isn't that hot?"

"I... Yes, she is hot." I replied, a little hesitantly. However, her comments about her girlfriend's body were so natural, so they didn't make me feel uncomfortable. "She has amazing legs. Her ass looks so bouncy in shorts."

"I know! I love her ass so much!" Sarah giggled before kissing my cheek. "I love you, Liam. Have a good night!"

She walked behind Zoe, into the bedroom, then she went back out and left some clothes for me on the sofa. She locked the door as soon as she went in and closed it one last time. Of course, it would be weird it a guy like me walked into a room where two girls were sleeping, so I understood the locking.

I went to the bathroom and turned on the shower. As I got naked, I couldn't stop imagining Zoe's amazing legs, nor Sarah's perfect boobs. I felt the water running over my body, and I slowly moved my hand towards my erection.
