Haruka started to lift her blouse, revealing her massive H-cup breasts, at the same time, Natsu-nee unbuttons her blouse, also revealing her H-cup breasts, they both started unhooking their bra, I just stared both of their breasts swaying while both of them struggles to unhook their bra, after a couple of seconds, both of them finally removed their bra, I stared both of their breasts, Natsu-nee's areolae is bigger than Haruka's, but Haruka's areolae and nipples are much pinkish than Natsu-nee.

Without realizing, I walked towards both of them, It's like I was hypnotized by their beautiful breasts, I then started to play with Haruka's sunken nipples, I want it to get erected so I can compare it with Natsu-nee's big nipples, Natsu-nee looks at us enviously, not long after, Haruka's nipples slowly erects itself, I compared it with Natsu-nee, Natsu-nee really got a big nipples compared to Haruka's, I then pressed their nipples together, I use Natsu-nee's big nipples to penetrate Haruka's inverted nipples then began moving them back and forth, It's like I use Natsu-nee's nipples to fuck Haruka's nipples. I then look both of their face, they really enjoyed it, after just 40 seconds of doing it, both of them grab my hand and said,

[Cumming!!! I'm cumming from my breasts!!!],

they both leaned on me, I then guide both of them towards the bed, I remove Haruka's pants and panties, then I began fucking her in missionary position, Natsu-nee looks at us while she masturbates. As I thrust harder, Natsu-nee grabs my hands and guide it towards her vagina, I began fingering Natsu-nee while fucking Haruka, both of them moans louder, after 15 minutes of fucking, as I'm nearing my climax, I separated from Haruka and shove my cock to Natsu-nee's pussy and cums inside her, the three of us breath heavily, then they both said,

[Haaaah Haaaaah Haaaaah Haaaah that was great],

we both talked after that sex, Haruka said she cums 4 times from that sex, while Natsu-nee said she cums 5 times when I fingered her, then they both hugged me, I then whispered to them,

[Let's do it again],

We ended up doing it 8 times. Thanks to our current relationship, Natsu-nee become much more livelier than before.

2 weeks have passed by, It was Friday night, I just got home from work, as Haruka and I eat our dinner, Haruka said,

[Darling, Grandpa is coming to Shinjuku tomorrow to visit my Grandma, can I spend the whole weekend with them?]

[I don't mind, I also have an emergency meeting tomorrow, you can lock the house when you leave, I'll just bring the spare keys]

I said,

[Thank you darling, and don't overwork yourself, I'll prepare the dinner tomorrow before I leave, so you can just reheat them by night]

Haruka said,

[Thank you honey]

I said,

then after we finished eating and wash the dishes, Haruka welcomes Natsu-nee, at this point, it become a routine now, we started having threesome in the bedroom, after doing it 7 times already, I separate from Natsu-nee then approach Haruka and asked,

[One last time babe]

[Nope, we both need to get up early tomorrow]

Haruka said,

so I just kissed her, Natsu-nee looks at us, then she whispered to me,

[Yuu-chan, If you still want to do it, you can always use me]

I got hard on, when Natsu-nee said that, but I grab her shoulders and said,

[I'm good]

Natsu-nee then leaves then I prepare to sleep.

Saturday comes, I wake up early, Haruka is already cooking breakfast, I then suit myself up, ate breakfast with Haruka then leave the house, I waited inside the meeting room for 30 minutes, suddenly my phone vibrates, I got a mail, It was from my boss, I read it "The emergency meeting is cancelled today", I got angry by this, I wake early for nothing.

I then began walking back to my home, I'm Infront of my unit, tried to open the door, but it was already locked, 

[Haruka already left]

I thought to myself, while grabbing the keys on my pocket.

As I relaxed on sofa on the living room, I mailed Haruka that my meeting got cancelled I'm home alone, Haruka replied "That is great, you now have a time to relax yourself, if you want I'll mail Natsuha-senpai to come for you", I replied "I'm good, thanks" then I opened the TV, as I'm watching someone rang the doorbell, I went to see who It was, I opened the door, It's Natsu-nee, 

[Natsu-nee good morning, what do you need?]

I asked,

[Haruka asked me to look after you, Yuu-chan]

she said, as she walks inside towards the living room,

[I'm good Natsu-nee] 

I said, 

[Haruka also said that we can do it, Yuu-chan]

she said, while she straddles on to me, I immediately got hard, 

[Stop it Natsu-nee]

I said,

[But Mr. Yuu-kun down here don't agree with you, Yuu-chan]

she said, while playing with my cock,

She then began unzipping my pants, pushed down my boxers, and began massaging my cock, I tried to hold in, then while Natsu-nee's left hand is giving me handjob, her right hand began unbuttoning her blouse, when I saw her body, I finally gave in from the temptation, I remove her clothes, then I began fucking Natsu-nee, while she straddling on me, she then said

[Finally!! after a very long time, a real moving cock, yes!!! Ohhh!! Ohhh!!]

As I thrust harder, she let out sexy moans, she then said,

[That's it Yuu-chan, you're doing great] 

Then I kissed her while fucking, she violently kissed back, looks like she's been longing for a kiss, after 18 minutes of fucking her, I cum inside her, we both breath heavily, while she's leaning on me, she said,

[You've really become good at sex, Yuu-chan, I cum 7 times from that sex]

We both then lie in the living the room floor, and I asked

[While we were having sex, Natsu-nee you said "Finally!! after a very long time", is that true?]

Natsu-nee then looks at me and said,

[You see, Yuu-chan, the last time someone penetrates me properly was from that incident we had way back in high school, after the incident, I only masturbate to quench my thirst for sex]

[That's why you are very tight]

I said,

We then started doing it again, we indulge ourselves in sex, we did until dusk, turns out we did 12 times, It was my new record, Natsu-nee then leaves, because she said her deadline draws closer, I thanked her for the company.

Sunday comes, I prepare my own breakfast, after eating my breakfast, I just watched the TV. When the noon comes, Haruka comes home, I welcomed her on the door, as I carry her belongings, she began to kiss me passionately, after a couple of minutes, she breaks the kiss and said,

[I was so lonely last night]

she started to kissed me again, after couple of seconds, she breaks off and said,

[Did you do it with Natsuha-senpai?]

[I'm sorry Haruka, I did it with her]

I said, 

[Don't worry, I'm the one who suggest it to senpai]

she said,

[We'll make lots and lots of love today]

I said.

After cumming inside Haruka for the 9th time, I look at Haruka, she's breathing heavily, I was about to fuck her again, when I noticed a small drop of liquid from the tip of her nipples, I inspect it, then I tasted it, it was milk, I shouted with joy, Haruka looks confused, I then said,

[Look honey!! your breasts started to produce milk!!]

I said, while pointing at her nipples,

she then grabs a pregnancy test on a cabinet inside the bedroom, went to the toilet, while I wait outside, after a couple of minutes, I saw Haruka's eyes started to cry, I then asked,

[What's matter? what is it?]

[We're gonna be parents]

she said.

While we hugged each other, the bell rings, we both went Infront of the door, Haruka opened the door, It's Natsu-nee, Natsu-nee then walks to the living room, she then show to us her pregnancy test, it's positive, turns out, both of them are pregnant, Haruka hugged Natsu-nee and congratulate her, Natsu-nee congratulate Haruka too, then they both hugged me.
