I knew for a long time that my husband lusted over my younger sister. Her boobs, growing up, quickly outpaced mine and she's been a hottie ever since. I really can't blame him. But, the truth is, I've kind of had my eye on her own husband and now, for my husband's birthday, I was going to give him the present I knew he so wanted: my younger sister. Oh, more happened than just that, we had a whole week living with each others hubby and that was just the beginning.
