The father of a teenaged daughter

how I discovered how much my daughter loves sucking cocks.

I came home from work and headed up stairs to change out of my work clothes. My wife told me Sally was in her room with her boyfriend Bob and two of his friends. She felt there was less chance of anything happening while his friends were in the room with them.
I had just got to my room when I heard Sally's door open and Bob was guiding her out of her room. He was standing there holding her arm and his cock was hanging out of his pants. I could see in the room his two friends were fixing their pants. Sally was topless her face was covered in cum and she had some on her breasts. her eye lids had a large amount of cum, and she could not open her eyes without it going on to her eyeballs.
Bob and his friends bolted out of there. I took her arm and guided her to the bathroom.
Sally was saying "you guys hard a load and half. I have never had so much cum on my face. I can't wait to see the pictures. Tony have you still got those pictures from last time.
When she didn't get a reply took two fingers wiped some of the cum from her face and said. "Hey Tony remember this."
She then her fingers in her mouth and sucked the cum off of them. Sally gave and smile and asked "Who wants to kiss me on the lips this time. No takers? This stuff doesn't taste bad. I have swallowed enough of it. You want to suck on my boobies? as she talked, she reached up and cupped her breasts. Her breasts are teardrop shaped, and she managed to lift her boob, so the nipple pointed up and she managed to get it in her own mouth and suck on it. Then she sucked on the other one I quickly noticed how big her nipples were.
I thought back to before my wife Hellen had a baby her nipples had been small after breast feeding, they had gotten bigger. Sally's nipples were a little bigger than her mother's. I took her to the sink in the bathroom, ran some water until it got warm soaked a flannel and wrung out the excess water and handed it to her. Just before I left, I reached out took hold of her nipples and gave them a little tug up.
When she came down later, she had talked to Bob on the phone and knew what happened.
I was in my study playing games on my computer when she came and told me how much she loved sucking cocks. Her first boyfriend got his older brother to show her porn on his computer of a woman sucking cock. She sucked them both off. she enjoyed watching their faces and seeing their orgasm faces. both brothers wanted her to go from room to room and suck of them off. she wanted to do it in the same room at the same time. after a few weeks they had split up and she found a new guy. she then listed out all the guys she had dated with a brief description of size and length of their cocks and the taste of their cum. Meanwhile sally had knelt down in front of and took my cock out and she started sucking me off. this was the best blow I had ever had. My wife has never got past her gag reflex. My daughter deep throated my cock and swallowed my load.
Now she sucks me off once or twice a week. bob and his friends came back, and sally even showed a few pictures of her sucking their cocks. One in her mouth and one in each hand.
