My 25 year daughter Sally has a mentally impairment. Until February she was fine, then her epilepsy meds were change, at first she was fine. But by April she became hyper-sexual. I would find her naked and masterbating all the time. Her tablet was full of links to lesbian sex sites. I spoke to the doctor and the med where changed. But it was two late she became worst. Then one Friday I came home early from work. It was early and I heard noise from Sally's room. The door was only open a crack I peeked in and was shocked. Sally was naked on her bed and the 13 years girl Kelly from the next apartment was also naked and licking Sally's pussy. I just stood there as Sally started to cum. Finally Sally pulled Kelly on the bed and they went 69. I watched for 5 mintues then they both came. I quietly left the apartment knowing what I had to do to protect my daughter. That night before bed I went to Sally and asked her what she was doing with Kelly. Sally said that Kelly was her girlfriend now and have sex. I said that Kelly is very young and that you can get in trouble being with her that way. Sally started to cry saying she loved her and wanted sex with her. I know baby i said, but from now on Mommy will have sex with you when ever you want. I opened my robe and gave my body to Sally. I had never like lesbian, but now I had to be one to protect my daughter. I licked her pussy, and ass until she came. I kissed her a lot and sucked her boobs. I let her do the same to me, not wanting to cum but doing so anyway. A year has passed, we share my bed. Sally's sexual needs have only grown. She is naked most of the time and masterbates constantly. I'm eating her 4 or 5 times a day. She has also been fucking me with a strap on. I work close by and come home at lunch to lick her and make her cum. I setup spy cams and know she is still with Kelly every day. The poor girl is so in love with Sally. I don't know what else to do. I'm trapped in a lesbian sex relationship with my daughter. The worst part is when I'm masterbating, I'm think of Sally's body and mouth on my pussy. I can't cum unless I think of her. On the weekends I actually don't want to do anything but have sex with Sally. I gave become addicted to tasting her pussy. This started to protect Sally, but now I desire it also.
