It was the girl's 18th birthday celebration. They'd actually turned 18 a few months before at college, but we always celebrated their birthdays together. Lisa had just returned from the store with supplies for the celebration while Shawna had remained behind to fix dinner.
We'd gone to the beach that day and after coming home, I decided to shower. After a long day of beating myself up over my fantasies about Shawna, my daughter's best friend...a girl who was like as second daughter to me, I'd finally managed to resist the urge.
For the past few days, I'd been masturbating to visions of beautiful, young Shawna. But after coming home from the beach, I'd at long last been able to overcome it. I'd been so proud of myself for that and was starting to feel better about myself, thinking that there might be some hope for me after all.
Then it happened.
Coming out of the shower, I'd heard a crashing sound downstairs immediately followed by Shawna's shriek of pain.
Reacting as any parent would, I ran downstairs without concern for myself, clutching at the towel around my waist to discover that Shawna had burned her arm with a pot of boiling water.
Somehow, in the commotion, my towel had come off. As Shawna pressed her face into my chest in tears, I'd comforted my second girl unaware that I was naked until it was too late. I'd grown erect, right between Shawna's bare thighs.
The rest is...well...some kind of sick and twisted history.
Shawna had apparently become aroused by our intimacy, and to tell the truth, so had I. I tried to resist, but overcome by my recent lust for my second daughter...I ended up fucking her in the kitchen while my daughter Lisa was at the store.
Lisa had come home, unaware that her fucked-up father was banging her best friend in the kitchen and nearly caught us.
Now, I crouched, naked, in the doorframe of my bedroom, barely daring to breathe, listening to the two downstairs. Shawna had been completely naked during our sex and had apparently run into the downstairs bathroom as Lisa walked in.
I heard her come out and greet Lisa.
Lisa was shocked at the burn on Shawna's arm, though I knew it wasn't serious thank god.
But the burn on her arm was the least of my worries now.
I had just fucked the hell out of my daughter's best friend, who was like a daughter to me, and I was scared to death and at a total loss.
"I burned my arm fixing dinner," I heard Shawna answer Lisa's surprised question as she came out of the bathroom.
"Jeez, Shawna, are you okay?" Lisa said worriedly.
"It's nothing serious, dad took care of it."
I winced at the reference to me.
"Well, thank goodness it's nothing serious. Hey Shawna, are you going to wear your bikini the rest of the evening?" Lisa laughed.
"Uhm....no..."
There was a moment of silence, until I heard Lisa exclaim in surprise.
"SHAWNA!" she said, sounding shocked. "For fuck's sake, you can't walk around like that! Daddy could come down at any minute!"
I could only imagine what Shawna had done.
"I'm just playin' Lisa" Shawna said, breaking into fits. It seemed that despite the fact that Shawna and I had fucked like wild animals in the kitchen only minutes before, she was unaffected by it. Shawna was being her usual self with Lisa.
"Daddy!" Lisa called upstairs from the dining room. "Are you comin' down?"
I was silent.
"Imma go change," Shawna said, climbing the stairs.
Quickly, I shut my bedroom door and sat on the edge of the bed. The towel lay on the floor at my feet, forgotten for the moment.
What had I done? What the fuck...what in the name of god was wrong with me?
How...I wondered...how in the hell could I have allowed that to happen?
How could I have fucked Shawna?
I knew that I'd been fantasizing about her since I'd come home to find her sitting on the couch in her sleeps shirt and knee socks on the couch.
I'd gone into the kitchen to fix myself a drink. When I came back out, Shawna's panties were lying on the couch next to her. I still didn't know if she'd taken them off when I was in the kitchen or if they had been there and I'd missed them when I initially came through the door.
Shawna had stood up and walked by me, and I caught a glimpse of something I shouldn't have. That's when the fantasizing started...hell, that's when I'd starting masturbating...picturing myself fucking her.
And now. Now, it was too late. I'd actually done it. I felt like shit. I felt like the biggest piece of shit on the planet.
There was no taking it back. I couldn't turn back time and undo what had happened in the kitchen. I couldn't un-fuck her.
I had no idea what I was going to say to her, or whether I could even face her again. What would she think of me...the man who had helped raise her from childhood...the man who she lovingly called her second dad? The man she trusted and looked up to?
