I (38) can't stop eating out my (18) year old daughter. About 6 months ago, I walked in on her using the end of her brush (plastic and hard but not good hard lol) to masturbate. I''m gonna admit, I got SO wet watching her to this, but explained my concern over using things to masturbate that aren't mean to be entered in to the vagina. She was really caught off guard and embarrased, but I assured her was natural and we could order her some toys or go buy some locally. I told her she could tear her vagina and asked If I could take a look to see if any damage was done (check for swelling etc) I did mean for this to be purely nurturing, and she was shy but eventually moved the hoodie she had bunched in front of her when I walked in on her butt naked. When she revealed her beautiful hairless mound (she shaves very well) and caught the scent, my pussy did tingle, but I was also genuinely concerned. And kinda pushed and prodded on her labia and around her vaginal entrance to see if she was bleeding or swollen.. While I was doing so, I noticed she started whimpering and kinda hunching at the air, and so my innocent tracing turned into swiping the slit , then rubbing her clit and before I knew it my fingers were in there. I was shocked and pulled them away and she said "Mommy, please don't stop. " and she said up and lifted up my shirt and placed my big heavy breast in her mouth and started sucking my nipples and that DID ME OVER. I laid her pretty body back down and momma started licking all of her girl up, I loved tasting her juices and feeling her tight pussy around my tongue . She came so hard she was almost crying then I got on top of her and rubbed my pussy on hers (they were both so wet, it felt electric), watching my pussy rub all over my sweet girls and seeing her erect nipples and innocent face quivering, I came probably harder than I ever have in my life (don't tell my husband). That was 6 months ago and I have not stopped, sometimes it's MULTIPLE times a day. She even skipped school a few weeks ago just so she could stay home and ride my face and she loves going down on mommy. I keep thinking we should stop, but almost every morning I see her sweet pussy peeking out of her night shirt before I wake her up and before I know it I'm between her thighs again. Am I permanently damaging her?
