I caught dad and my sister but kept quiet

Living in North Dakota is a pretty boring place I played baseball on a small local baseball team and that was all the excitement I really had. I live there with my dad and my sister mom had passed away years before and we were just settling in it took us a long time to accept the fact she wouldn't be back. My dad was always closer to my sister who was 17 then he was to me but I just took that as being Daddy's little girl type of situation I wasn't jealous it really didn't affect me.

I never thought that something would happen between them never even crossed my mind. Until the day I saw it with my own eyes I caught them so to speak. I came back in from a day long round robin baseball tournament. I was supposed to be staying at a friend's house overnight but I wasn't feeling real great and told him I prefer to stay in my own bed so I headed home. Went in up to my room through all of the baseball gear down went down to the kitchen to get something to eat the car was home but nobody was around.

We had two bedrooms upstairs mine and my sisters and my father had a master bedroom suite in the back on the first floor. I thought I heard some noise coming from the master so I walked over the door was cracked and that's when it hit me they had something going on. I watched through the door my sister naked her legs kneeling at the edge of the bed and my father between her legs eating her out. At this point in my life I was still a virgin but I was jacking off daily sometimes a couple times a day. I was mesmerized I couldn't stop watching and as I watched I started to realize this was getting me tremendously excited my cock started to stand up. He continued eating her out for a while then he pushed your back on the bed slightly put her legs on his shoulders and pushed that cock deep inside her only words I heard were her saying slowly Daddy please now I've got a big issue because I've got a raging hard on that's leaking prelude do I finish myself off and get out of there or do I edge myself and watch them have sex.

I chose to stay and watch but I had to be careful I was right on the edge of shooting off my Hope was I could watch until they finished then I could go into the adjoining bathroom where I was standing finish myself off Best of both worlds. He slowly fucked her spreading her legs wide and hanging on to her ankles from my angle it was hard to see her face but you could tell that this was not a forced act she was definitely a willing participant.

He fucked her for what seemed to be 10 or 15 minutes I heard him tell her he was ready to blow he said over and over I'm going to blow I'm going to blow. I was so close but needed to wait he removed his blood and gorge cock held it straight up in the air jerked himself about three times and he unleashed a massive amount of sperm all over her stomach all the way up to her shoulder across her tits.

That was it I couldn't wait anymore I slipped into the bathroom put a tiny bit of liquid soap in my hand three strokes and I shot a massive load all over the side of the toilet and the toilet tank fuck it was good. I cleaned up and when I left the bathroom they were both in the kitchen. My dad said we didn't hear you come in I said oh yeah I've been upstairs in my room I just came down here to get a book and had to use the restroom. I was pretty convincing that I hadn't seen them and I left it at that.

A few hours later dad left to go shopping. I didn't want to say anything but I just couldn't help myself I told my sister I said I saw you guys I know what you do. She turned bright red I told her look I'm not going to say anything to Dad I don't want this to blow up into a big deal but based on what I saw this is something that has been going on a while. She confessed to me that she was fucking and sucking dad off for the last 6 months or so. They had gotten drunk ended up having sex and realized this can be good for both of us.

I told her her secret was okay with me I wasn't going to say anything and then I explained to her how excited I got watching them. She knew I had a girlfriend but I explained to her that it was pretty non-sexual at this point my sex life was limited to jerking myself off. I told her that my girlfriend let me play with her tits suck on them a little but it didn't go any further and she didn't help me with my hard problem.

My sister looked at me and said you've never had intercourse? I told her never she said to me let's take care of that I told her I don't know I feel kind of strange she said look dad will be home soon why don't we get together when he goes to work tomorrow. I told her what we can talk about it anyway but I assured her again her secret is good with me. She also wanted me to know that she was a very willing participant she said dad was a good fuck and she got as much out of it as he did if not more. I told her I was happy for her and left it at that

The next morning just like clockwork we had breakfast and dad took off for work it's just her and I at the table she reaches under her thin t-shirt takes her bra off tells me she hates these things there were two restrictive and of course her nipples showed through that shirt. She told me she said look I'll help you out with this virginity thing but it's got to be something you want. I asked her if this is something she was sure she wanted she said the only sex she got was from Dad so it would be fun maybe to have something different. We went off to my room no questions asked she pulled her shirt off exposing those tits absolutely great I could have sucked on those and been happy but it wasn't going to stop there. She undid my belt on buckled my pants slid them down and I was just in my underwear but my cock was it full attention she laughed but she said she understood never been put in that position before.

She couldn't believe that my girlfriend had never jerked me off or given me any head I told her no I always came back home had to deal with it myself. She pulled my pants down remove them for me then slowly she slid my underwear off exposing my cock she said wow for somebody your age I'd say you're a bit over average and she just lightly massaged it she reached down to my sack play with my balls that I could feel were starting to tighten up. I started to become uncomfortable and jerk around at which point she stopped, telling me that she didn't want me to go off too soon. She pushed me back on the bed and started to suck my cock I told her look I was going to finish very fast I could feel it my nuts were drawn up I knew that I was ready she picked up the pace a little I couldn't hold back I told her I was going to shoot she took it out of her mouth and gave it a firm stroking and I think that first load must have shot 18 to 24 in out of my cock into the air she laughed with her free hand she firmly massage my balls kept stroking until she got every ounce of spunk out of me.

I told her I said that was great thank you so much I went to the bathroom to clean up I came out started to grab my clothes she says whoa wait a minute she said you're still a virgin. I told her yes but at least I've had oral sex. She said look it's not going to take you any amount of time to get another hard-on I told her yes I know sometimes I jerk off back to back with only 5 minutes or so in between. She reached down and played with my limp cock massaging it playing with it then she stuck a finger between my legs and started playing with my ass it felt strangely nice she went down to give me a little head and when I was standing at attention she started rubbing her slit you could tell it was getting a little wet she laid back on the bed she took my prick in her hand and she eased the knob up and down between her legs each time I pushed forward a little bit more. I couldn't take this I pushed all the way into her and I had to stop I felt my load on the horizon and I wanted to make this last a little bit her cunt was tight and it was so warm. I looked at her no doubt she liked it she was pinching and pulling her nipples and the look on her face was that of ecstasy.

I started once again slowly but I knew it just wasn't going to last so I started banging hard and fast she told me she wasn't on birth control but I was out of control I banged hard and fast and I felt my nuts are up shooting that warm baby batter deep inside her hole. She said I told you I'm not on birth control. I told her I just couldn't help it it happened I couldn't get it out I wanted it. She got a baby wipe told me to clean her up good down there with the baby wipe which I did. She then spread her thighs wide parted her curtains to expose a tiny little bump which I now understood was a clitoris. She told me if I stimulated either with my tongue or fingers she would be willing to feel as good as I did there was no way I could tell her no after what she did for me. I started rubbing it she really moaned and groaned she was getting into it but after 15 minutes she still hadn't reached climax she asked me if I would mind licking it a little I told her I would try I wasn't real excited to do it but again I kind of felt like I owed her. So then I went I could see her clitoris had swollen up from being played with I began to lick and suck on it she started grunting like a wild animal her hips started bucking up to meet my mouth I sucked long and hard on it then she says fuck I'm coming I sucked even harder on it until she grabbed me by the hair and pulled me away telling me it was too sensitive. She told me I gave head as good as Dad I'm not sure if I was proud of that or not but I got mine and she got hers and all was good with the world. She said she would have to take a plan b if she could find one. I didn't know what the hell that was she told me it was a pill you could take if a guy came inside you it would prevent you from being pregnant I didn't expect that big of a load because I'd already emptied your sack once. I told her it looked like more than when I jacked myself off. She said that was to be expected and I guess she was right. I went to the hall bathroom and took a shower her room had its own shower she showered called her friend who said she could get her a plan b so she got in her car and drove over I guess getting what she needed. When she came back she told me everything would be all right she said she had to get on birth control because she had just been lucky with Dad and she prefers come deep in that hole but doesn't want to get pregnant

I thanked her very much and told her of course I wouldn't say anything to anyone and she told me she said look you're my brother and I love you she said this doesn't have to end with this one time. I told her I said you really have it good you've got Dad giving you cock and now you're telling me that we can repeat this. She said yes but she never wants one finding out from the other one and of course that's never going to happen. She told me without any shyness at all if I found myself needing to lose a load to let her know if dad was home we could always take a drive to the park and she could suck me off or if he wasn't home we could have nice sex. But she also told me that if she ever was in need and it was inconvenient for Dad or myself to take care of her cuz everyone was home she might ask me to go for a ride to the park. Upon leaving she said to me next time I will rim you and I want you to rim me. I didn't understand what that meant but I didn't want to look completely stupid. But it looks like the next time we have sex we're going to be eating each other's assholes as well.
