You don't deserve it OP. you expect your boyfriend to have private phone calls or give you some warning! tell him in future to make sure he tells you!

He could have at least warned you beforehand that you were on speaker phone.

at least you know it works.

Well you can try it anyway

Meh, at least he has a cool sister. Mostly I though it was strange (but cool) that you're from the U.S. but you use the word, "cheekily".

I hate when people put you on speaker phone without warning you. This one girl I used to be friends with did that to me when her friends were around because they would eavesdrop anyways. I actually almost asked her out when I was on speaker phone. If I hadn't changed what I was going to say when I heard her sister say something ... I feel your pain, OP. People should tell you when you're on speakerphone.

Lol worst feeling ever

The same thing happened to my fiancée. She said something dirty and I had her on speakerphone in front of my grandmother and my father. Just be happy it was only his sister. :P

that's great free review

Um, I have two questions. One: Why did you boyfriend decide you should be on speaker phone, and two: what was the special move ?
