Heading into the bed room

Lisa led her boyfriend through a door into a bed room, turning around and gesturing for Millie to follow them.

Millie felt a bit weird. She had many times fantasised about being the guest star in a ménage a trois, but not in this way with her basically being invited so that the boyfriend could use her ass hole instead of using his girlfriend's anal opening.

They sat down on the bed, Lisa in the middle, and Millie and the boyfriend on each side of her. The boyfriend had an amazed look in his eyes, maybe he thought this was some sort of test or something similar and not that he was about to stick his cock in a busty blonde's ass with his girlfriend's approval. They just sat there in silence for a while, none of them speaking, until the boyfriend finally broke the silence:

"So... How do you know each other?" He turned to his girl friend and asked.

A brief look of panic shot through Lisa's eyes, but she quickly recovered and said:

"Do you want to talk or do you want to see her tits?"

The boyfriend got a surprised and horny look in his eyes and seemed unable to speak, but Lisa looked at Millie and said:

"Show him your tits."

Millie pulled her top over her head. The boyfriend just stared at her breasts which looked like they were about to overflow her bra.

Lisa smiled and nodded, saying:

"And the bra."

Millie reaches behind her and unclasped her bra, and her big tits tumbled out in front of the boyfriend's horny eyes.

Lisa looked at her boyfriend, then leant in and started licking one of Millie's nipples.
