Two old friends who haven't seen each other for quite a while meet at a bar for drinks. They get to chit chatting about this and that, and then one says to the other "So how's your sex life?"

And his friend says "lousy. Haven't had sex in months. How's yours?"

And his friend says "fanatastic, can't complain".

First guy then asks "so what's your secret to having such great sex?"

And the second guy replies "Well I play this game with my wife called Rodeo. Pretty simple really. We start engaging in foreplay and both get pretty excited, and then I start doin' her doggie style...and then just as she's about to orgasm, I lean forward and whisper in her ear your sister does it better and then I try and hang on for dear life for the next 10 seconds!"

Tah-dah-boom
