The morning before her 19th birthday, Mandy was outside tanning by the pool. She was probably thinking I was in my office, as was my usual schedule for that time of the morning, when I looked out the kitchen window and saw her strip off her bikini top.
My cock, already semi-hard, immediately started throbbing as I stared at the most beautiful tits I had ever seen. Full C cups, with delicious strawberry areolas, had my mouth watering to lick, suck and eat them up. I kept telling myself to look away, that it was wrong, and that she was my daughter, but my eyes stayed glued to Mandy's chest.
My cock was so hard that my jeans could hardly contain me. Finally I unsnapped my pants and stroked my cock. I knew I was close to cumming right then.
As I looked at Mandy, I saw her stroking sun block on her beautiful tits. Knowing she would be outside at least long enough for me to cum, I decided to jerk off right there in the kitchen so that I could admire her breasts.
I stroked my cock hard, imagining Mandy's mouth sucking me while I enjoyed her tits up close. I could feel my balls tightening and new any second I'd be cumming. I was so absorbed in my fantasy and my cock drenching my hand, that I didn't hear the backdoor open.
I looked up when I heard Mandy gasp. "Daddy?! What are you doing!"
"I'm sorry, baby," I said after stuffing my cock into my pants. I couldn't think of anything else to say. Really, what more could I say after she'd caught me jerking off in front of the kitchen window. I didn't know what to do.
Then before I could do or say anything else, Mandy ran to her room and slammed her door.
I felt so ashamed that she had seen me. I wanted to go after her and try to explain, nut I knew she was too much like me to listen right now. I would just have to wait until she calmed down and came back out to tell her how truly sorry I was and that I wanted to make it up to her.
For the rest of the day, Mandy avoided me. I was afraid that she might continue to ignore me, even though tomorrow would be her birthday. We had had plans to spend the day together, but now I was not sure she would agree.
I was about to give up and get ready for bed when I heard Mandy coming down the stairs. When I looked up from the couch, I saw her standing at the bottom looking at me. I couldn't help but notice that she was wearing a little, almost see through, tank top and tiny pink shorts.
Forcing myself to remain calm, I said, "Hey, sweetie."
"Um, hi, Daddy." My little Mandy couldn't seem to look me in the eye, and this broke my heart. Because of me, our close relationship was broken.
"Daddy, can...um, can we talk," she said as she walked to sit next to me on the couch.
Swallowing I said, "Sure, angel. I think that is a good idea."
Mandy peeked at me, but still wouldn't look at me. Knowing I needed to apologize, I spoke up before she could say anything else.
"Sweetie, I'm very sorry about what you saw this morning. I never meant for you to see any of that."
"I'm sorry for just walking in like that, Daddy. I thought you were still in your office," Mandy whispered.
I rushed to interrupt because she had nothing to apologize for. "Mandy, honey, don't apologize. You had no way of knowing I was there or what I was doing. And I shouldn't have been doing that there, anyway. I'm very sorry, baby, and I wish there was some way I could make it up to you."
For the first time all day, Mandy looked at me and smiled.
"Well, Daddy, I'm sure there is something you could do. Maybe an extra big present for my birthday?"
I jumped on this chance. "Sure, sweetie, anything you want, just name it."
"While we are out tomorrow, I will think of something for you to give me, Daddy." She jumped up from the couch and went to the stairs. "Goodnight, Daddy. See you in the morning."
And like that, she was gone.
The next day, Mandy and I went to the mall, had lunch at the most expensive restaurant in town, and I spoiled her as much as possible. When we returned home we watched all of her favorite movies.
When the last movie had ended, it was almost 11 o'clock, and I was getting sleepy. I also needed to jerk off because my cock was rock hard at spending so much time around Mandy. I suggested we both head for bed, and Mandy agreed.
When I heard Mandy's door close, I gave in to the need to release my cock. I was so hard and ready, there was pre-cum already soaking the tip. Thinking Mandy was in bed, I closed my eyes and pumped my cock in my hand. It wasn't going to take long for me to cum.
I jumped in guilt and rushed to cover myself when I heard Mandy's voice from the stairs.
"Daddy, I forgot to tell you what I wanted for my present."
Holding a pillow in my lap, I looked over at Mandy and choked, nearly swallowing my tongue. Mandy had come downstairs in the skimpiest blue underwear I had ever seen. Her bra barely held her delicious tits and I could almost see her areolas peeking about the lace cups. Her panties were sheer blue lace, showing off her bare pussy for all to see. I felt my cock jump under the pillow and groaned.
