So, my girlfriend and I moved in together recently. We've gotten a little more serious but no mention of marriage yet. Our apartment is not too small really, as it has a guest bedroom we use as office, but each room is tiny, so the bedrooms, kitchen and living room are really close.
After a couple of months, my sister in law came to the apartment and stayed with us. Gotta describe them both now. My girlfriend, Sheila, is short, a little well rounded and light blonde. She got a big ass and big tits, but she is not really fat. Her skin is a very white and her eyes are blue. She is 26 (my same age). Her older sister, Samantha, 30 years old, is taller, way taller, almost my size. She has black hair, almost black eyes and her skin is a little tan. Her tits and ass were not nearly as big as her sister's, but she still has a good figure. Their differences are explained because they have different fathers, Samantha's father abandoned her and her mother shortly after she was born. Sheila looks a lot more like her mother.
She was going to stay for a few weeks in the summer. Her company had her working on a far away town for a year or so, and she was going to have to go back after a month.
The second day she was here, we went out for drinks to celebrate (she had come by bus into the city and was destroyed the first day, so she just crashed into the guest room which we had readjusted as a bedroom with a bed/sofa). We drank a lot in a bar near the building, then came back to the apartment, very wasted. This time, I was the one who went to the bedroom and crashed. Slept a little, maybe half an hour, then woke up and stayed there. I could hear my girlfriend and her sister talking. They were trying to keep quiet, but in their drunkenness they just made their voice sound like whispers, but were perfectly heard from the bedroom.
They talked about Samantha's love life. Samantha had finished a relationship with a boyfriend in this town she was staying at.
-Ugh, Robert was such a boring asshole after a while. Let me tell you, Sheila. You don't know how good we have it in the big city until you have to move into a little town. The cock selection is so small! Robert was like the only guy with a decent sized cock there! What I am going to do now?
-Hahaha just fuck someone else! I am sure you will not lack candidates!
-Oh yeah no, obviously. Look at me, bitch, please. But the problem is that all the good guys have small cocks! Robert wasn't huge, I've had bigger, but he was good in bed. But that was all there was to his. I was bored of him after a month. The sex was good, which made the thing last as long as it did but, Jesus, this guy didn't even read any book! You should have seen his living room. It was empty except for like a big TV.
-Yeah, Carlos luckily isn't like that. We met at the local theater even.
-Yeah, Carlos is great. Really funny guy. Can take a joke.
Carlos is me, by the way, the drunk boyfriend in the bedroom listening because he is too drunk to move and the floor is moving.
-So yeah, I am done with Robert, and there's no one in town who has a good sized, fat cock. I've been sampling, believe me.
-Oh you dirty whore!
They laughed.
-So, Sheila, how big is Carlos? This big? this big?
I heard Sheila laugh. I assume Samantha was doing some gestures with the hands.
-Oh come on Sheila. just this big? is that smaller than Zack? Zack wasn't that big, we measured it. Was it 5 inches long, 4.8 inches around?.
How did Samantha know the dick size of Sheila's ex-boyfriend?
-It's fine, really. It's not a lot of difference. I am not even sure it is smaller than Zack.
-But it is smaller than Jonathan! You are going backwards, girl! You have to go for the bigger dicks! Look at yourself! That big ass needs big cock!
-Hahaha oh shut up Samantha, Carlos may be listening!
They went back to not-really-whispering.
-But seriously. Jonathan wasn't even big. Just 6 inches. Now, he also had 6 inches of girth, which is good, let me tell you, but there's more fish out there! Bigger, fatter fish! And you are just here with a smaller guy than Jonathan? You are not advancing! Ok, how thick is Carlos.
Silence.
-Come on, Sheila! this much? this much?
I assume Samantha was gesturing. I don't know how thick my cock is (I know it is almost 5 inches long, but hadn't thought of girth, really)
-Sheila! I am barely making a circle with my fingers! that's barely a cock at all!
-Carlos is really good in bed. Better than Jonathan!
-I hope so.
Now, I knew that she had had this Jonathan boyfriend with a bigger cock than mine (didn't know about this Zack guy), but she had told me I was better in bed. I guess it was true if she was telling her sister the same thing.
-Sheila, I've fucked guys like Jonathan and Carlos. They are ok. And I've fucked big cocks. Really big cocks. Even the laziest, lamest guy with a big cock was way better. Way. Better. Your vagina just, dunno, gets roughed up a lot more and that's fantastic. Your labia and the walls just get stretched and it burns, and it hurts, I'll be honest. With the bigger ones it hurts every fucking time. But after a little while, maybe a minute, it is fantastic, no pain, just the fire in your vagina. Nothing like an average cock. which you just feel slide inside yourself, and you need to be playing with your clit to come. Sometimes you come without even touching your clit. Sometimes, if their cocks are really fat, the size just tickles your clit anyway. I haven't looked at it while fucked, but I suspect it just gets dragged along. It's just raw, earth shattering pleasure. You just feel owned by the big cock, it's great. After that, fucking a regular cock, is, well it's ok, orgasms are orgasms, but it just not the same.
-Samantha.
-Sheila you also have to think of the future! You moved in with this guy. What's next? Marriage? Kids? Imagine you have male kids. You may be dooming them to a small cocked life!
Both laughed.
-Although mother has confessed to me that your father has a much bigger cock than mine had. So maybe you have the good genes. Besides, you are smaller than me, so maybe a regular cock feels big to you.
More laughter and then silence for a while.
-Doesn't it hurt? I heard my girlfriend Sheila say.
-Oh yeah, I just said so. But it passes after a little while. The longest ones may hit your cervix and that shit hurts. The best cock is long, but not too long, and as fat as possible. Listen. I have an alternative. Fisting. Have you tried fisting?
-What's that.
-When they insert their entire fist in your vagina. It really hurts. No cock has a head bigger than a man's fist, but it is kind of close to being fucked by a big cock. Really hurts, but a decent alternative to a big cock, can give you some good orgasms.
-Yeah I am not doing that. Have you seen Carlos' hands? They are very big.
-Yeah, was thinking that.
Silence. They discussed getting more drinks, went to grab a beer from the fridge.
Dunno what had gotten into Samantha trying to convince my girlfriend that my cock was inadequate. Maybe it was the lack of sex, since she said she had not sex in a while.
Sheila broke the silence:
-You know what we should do? We should go measure Carlos. I have a sewing measuring tape in the closet.
-Ah I knew I could talk sense into your little brain. Remember when we did that to Jonathan? The look in his face when his sister in law just grabbed his cock and measured him? Samantha answered.
-And then you told him he was small. I had to give him so many blowjobs, you asshole! But since he was trying to compensate for his size, we had the best sex for a good while. You won me such a good fuck with that, Samantha.
-Yeah, so you told me. It always works like that. Remember when we measured Wilbur? He fucked me all night after that.
-Oh my god, Wilbur was so big. I've never had a bigger dick in my hand, before or after.
-Wilbur wasn't the longest I had, but his cock was fat, yeah. I've had better, but not much better. Although Wilbur fucking me that week we measured him? Maybe some the best sex I've ever had yeah.
What was this measuring thing? Were they just gonna ask me to wipe out my cock and put a tape next to it?
-We should do it now. I could use some fucking, Samantha.
-Is he going to be able to fuck you? He looked tired as fuck.
-Oh no, Carlos has stamina, that's good about him. He has fucked me drunker than this.
-Oh ok let's do this.
I heard them move around and come to the bedroom. I had no time to react. I just shut down my eyes and pretended to be asleep. The conversation had actually woken me up and I had semi erection.
Once they were in the bedroom, they started giggling and I heard clothes rustling. Then I felt Sheila's small hand move my shoulder.
-Carlos. Carlos. Wake up!
I opened my eyes pretending to wake up and looked up. The bedroom was dark, but some light came from the living room that illuminated the sisters from behind.
They were both naked. I couldn't make up all the detail in the darkness but they were stark naked.
