Yes they do

"Fine." Mariella said, Serena laughed.

There was a second knock at the door.

"Room service." A voice again called out.

"Just a minute." Serena replied.

They both took a piece of paper and a pen and quickly wrote a number on the paper; Serena took out her phone and taped on the screen and then smiled at Mariella.

"OK, nearest the random number wins." Serena said.

She put her phone down on the desk and they both looked, on the screen it had produced a random number '17'; Serena put her piece of paper down first, on it she had wrote the number '69'.

"Yes!" Mariella shouted as she put her piece of paper down with the number '13' written on it.

"Damn." Serena said.

"Go on, go get our drinks." Mariella said with a big smile.

She walked towards the bathroom and looked back at Serena as she heard her friend unlock the door, peaking around the door, Mariella watched as she opened the door and stood back.

"Hi." She heard Serena say.

"Hello, I am Thomas, from room service." Mariella heard.

Mariella looked around the door and saw Serena step back to allow a guy to walk past her with a tray with two drinks on it, she hid in the bathroom, a hand covering her mouth to stop herself from laughing aloud.

"Hi Thomas. You seem pretty young, are you sure you are old enough to be serving these drinks?" Serena asked.

"Yes, I'm 21." Thomas replied.

Mariella looked around the door again and she saw Serena sat on the corner of the bed, her legs either side of the mattress, Thomas was unable to take his eyes off her.

"What can I give you for a tip?" Mariella heard Serena ask.

"Um. Any... Uh, whatever you like." Thomas stuttered.

Mariella looked out into the room, she could not see Thomas but she could see Serena trace her fingers between her breasts and then circle her hard nipple, as she watched, Mariella brought her own hand up her body until she felt her own hard nipples.

"Isn't there something special I can offer?" Serena asked.

Mariella saw her open her legs wider as she pinched her nipples and watched from the bathroom.

"What can I... Uh, what would you?" Thomas started to say and then stopped.

"Would you like to touch me?" Serena asked.

Mariella watched as Serena sat back, she propped herself up on her elbows; Thomas just nodded.

"No need to be nervous, Thomas, you can touch me." Serena whispered.

Mariella gasped and quickly covered her mouth.

"Thomas, are you a virgin?" Serena asked.

Mariella couldn't see Thomas, but he didn't answer.

"Don't be embarrassed, it's OK. We are all virgins at first." Mariella heard Serena say.

She walked into the bathroom and sat down on the toilet, spreading her legs wide she ran a hand down her body as she listened, Mariella gasped as her finger stroked through her wetness and rubbed her clit, her other hand covered her mouth to quiet her moans as she pushed her finger deep into her pussy.
