Every Monday night my husband goes to my sisters house and helps her around the house. Me and my sister are close. We are sharing my husband. He has been sleeping with her for over a year now. And ever Monday when he is done with her (by the way he creams inside her too) I let him come home and shower then wait for him on the bed naked so he can do me too. I don't feel like this is a bad thing. My sister is willing to do more things then I am. Like a***. He lives a***. So do I just not as much as my sister does. So last night as he was on top of me pumping me hard I told him to call me by my sisters name and I felt his c*** get hard. He stopped and said "what?" I said it was ok if he wanted to sleep with my sister.
