Five minute later we heard the bedroom door slam and Veronica called loudly: “Donna, can I borrow your hair dryer?”
I smiled to myself and before Donna could answer, I said: “Use mine, it's under the sink.”
We heard the hair dryer start up and run for a few minutes before it shut off and the door slammed again and Veronica called from the hall: “Does anybody want anything from the kitchen before I come in?”
“No thanks,” I answered back.
She was trying to warn us she was coming into the room so she wouldn't catch us again. If Donna knew what her sister had seen…
The rest of the evening was TV and chit-chat and I invited Veronica to join us the following day. We had planned a picnic in Balboa Park. Veronica thrilled to be included. Donna gave me a dirty look.
In bed, I explained to Donna that if we were going to spend two weeks together it was better to make her a friend than ostracize her. That way she would give us our space when we wanted it and they would get along better when their parents returned, hopefully no more blackmail.
We made passionate love that night, calling out each other's name plus a few oh Gods and Jesus fucking Christs, moaning and groaning and screaming and I knew I was being louder than usual. It wasn't until morning that I realized we had left the door open and I think, subconsciously, I wanted that. Yes, I wanted Veronica to hear us.
The next few days went well; Veronica was at ease and the girls started to get along better. It was the fourth night we were together that I realized how close we were becoming.
We all went to bed at the same hour and I did not close the bedroom door, on purpose now. Donna and I spent the usual amount of time having sex, at least an hour and a half, sometimes two, depending how many times I could get it up. We stroked each other, I went down on Donna and ate her pussy and made her come twice, trice, then I got her up on her hands and knees and fucked her from behind, and before I was finished I lay down and she rode me until we came together. I was satisfied but Donna was a nymphomaniac and wanted more, so she crawled over and started to suck me into her mouth to coax my dick back to life. If I couldn't get the solider ready for another sortie, she would masturbate and then I would go down on her. I started to imagine doing this to Veronica and that got me up again. To do these nasty things with a 13-year-old cutie pie! Oh, I was a bad, dirty old man all right.
And then, on the fourth night, it was while I laid there on my back getting a very satisfying blowjob that I glanced over at my dresser and in the mirror I saw a sight I will never forget. In the mirror I could see Veronica in her bed. She was stark naked, exposing her beautiful 13 year old body to the air and the moonlight spilling in through her window and falling across her bed. She had her right had furiously fingering herself while her left was pulling at her nipples. It was plain to see that her gaze was fixed the same place mine: the mirror. She was watching her sister suck my cock and making herself come.
At first I thought this was my imagination getting the best of my eyes, but no: this was the real thing, and the little girl had been doing this, most likely, every night, getting a good view of every dirty bed thing. I found myself wishing I had introduced Donna to anal sex (she wasn't ready but curious) so Veronica could witness me packing her sister's fudge.
This little nymph watching and jilling herself off excited me and I figured I would give her something to really watch, ass-fucking aside. I pulled Donna's legs over me so she straddled me in the good ol' 69 position and I went to work on her pussy. I ran my tongue up and down her slit, sucking her lips into my mouth then flicking at her clit, then stabbing into her hole and wiggling it around. A few minutes of this attention and Donna exploded on my face-and I do mean explode, as a stream of fuck juice spewed out and splashed my mouth. I slurped up as much of the juices as I could and turned her around so I was on top and fucking her mouth. All the while I kept an eye on the mirror, watching the watcher. As I shoved my cock into Donna's mouth, making her gag now and then, I started to talk dirty in a loud voice. I told her how much I loved the feeling of her mouth around my cock and how good she tasted, how I loved when she came in my mouth, and how I wanted to come in hers. “I want you to eat all that sperm, you dirty whore,” I said, “I want you to be my cum-hungry slut!” Donna liked this talk and she took my cock into her mouth to the hilt, her pelvis slamming into her cheeks. From what I could see, this was having a similar effect on Veronica, as she was now ramming what had to be at least 3 fingers into her little pussy and pulling her nipples so hard I thought she would rip the flesh off.
This was just too much for my mind and I started shooting sperm deep into Donna's throat. She choked on it, spat some up, and tried to swallow what she could. Veronica had her own load orgasm that I could clearly hear, and I watched as she lay slack on her bed. I pulled Donna up to me and wiped my semen off her chin and chest and made her suck the remains off my finger. There was some in my crotch and pubic hair; I scooped that up and Donna ate it all, humming as she did so, her eyes closes in ecstasy. Out of the corner of my eye, I saw Veronica observe with a curious tilt of her head, and she was still rubbing her pussy.
Donna curled up beside me and I drifted off to sleep with her, knowing we had an audience and liking it.
Chapter IV. The Devil Inside Her and She Cannot Help It
I slept late the next morning. Donna had to work that day, leaving Veronica and I home alone. I was in bed, playing with my balls, and heard Veronica moving around the place. I got up and did not bother getting dressed, went to the bathroom and then to the kitchen to pour a cup of morning eye-opener. Veronica was sitting at the kitchen table eating a bowl of cereal and she glanced up when I walked in and did a double take as she realized I was stark naked. She stared at me for a few seconds, then looked away and asked, “Are you going to put clothes on today?”
“Why?” I replied. “You've seen everything I have already anyway.”
“What do you mean? People aren't supposed to walk around naked!”
“Just remember, if you look into a mirror and see somebody, they can also see you.”
Her head snapped around and as she looked at my face she began to blush the reddest shade I have ever seen.
She tried to act innocent: “What are you talking about?” but that didn't fly. She'd been caught and she knew it.
“Don't even try to go there,” I said; “I saw you watching me and Donna in the mirror last night.”
“I was not!” she cried.
“Okay, have it you way. You were just lying in bed naked and playing with yourself until you came and it just happened to coincide with your sister and me fucking. I mean, I guess you didn't see me feeding Donna my sperm with my fingers, huh?”
Her face was redder and her lip quivered and I could see she was going to start to cry. She was at a total loss as to what to do-this was new territory of experience for a girl.
“Veronica,” I said gently. “Don't cry. I don't care that you watched us. Just don't lie about it.” I sat down next to her. “And I don't care that you were masturbating. You are a beautiful girl, with a beautiful body, and it's only natural to want to feel the pleasure your body can give you.”
I reached out and touched her arm.
“But it's so evil,” she mumbled. “Nice people don't do that, only whores and sluts. I know the Devil is in me but I can't help it.”
I broke into a laugh which confused her and I said: “All normal people masturbate. Anyone who claims they don't and never have is a plain liar. Hell, I do it all the time and sometimes your sister likes to watch, and sometimes she does it and I watch and sometimes we do it together. There's nothing evil about it. Nobody gets hurt, do they?”
She shrugged. “Well, I guess not. I mean if you do it to yourself and it feels good…”
“Then there's no harm. What can be evil about feeling good?”
Her attention was less on my face than it was on my penis, only two feet away from her. She wasn't staring yet but sort of sneaking glances at it and wiggling her bottom around on the chair. I knew this talk was having an effect on her as it was on me as I was starting to get an erection. When I looked at her crotch and saw how wet her pajama bottoms were… well, that got me fully erect.
