A woman is in bed with her lover who also happens to be her husband, Bob's best friend.
They have had sex for hours. The wife is on top riding him when the phone rings. Since it is the woman's house, she picks up the receiver.
Her lover looks at her and listens, only hearing her side of the conversation. .. (She is speaking in a cheery voice)
"Hello? Oh, hi. I'm so glad that you called. Really? That's wonderful. I am so happy for you."
Still riding up and down on her lover's dick, she goes on,
"That sounds terrific. Great! See you on Sunday evening, love ya. Bye bye."
She hangs up the telephone and her lover asks,
"Who was that?" "Oh" she replies, "that was Bob telling me all about the wonderful time he's having on his fishing trip with you!"
