Oppai Family Bonus Short Story

One day when I arrived home, I found an unexpected turn of events happening.
Waiting in my house was an extremely beautiful flaxen-haired woman whose face was the spitting image of Rias'. It was Rias' mother, Venelana-san. And by her side was the silver-haired beauty, Grayfia-san. The wife of Rias' older brother, the Maou Sirzechs Lucifer.
Also, there was a young woman with crimson hair tied up backwards in a ponytail. Her face resembled Rias' a little, but the corners of her eyes were drooping and she had a soft expression. Breasts! Her breasts were big too. They were so assertive! Were all the women of the Gremory household huge-breasted? I thought Rias inherited her plump breasts from Venelana (who originated from the Bael Family), but it seems like the Gremory women were huge-breasted from the beginning.
This young woman is Rias' grandmother! Chysis Gremory. The previous Gremory family head! But well, really, there are only beautiful girls (with huge breasts) among the Gremory women and it is the best.
Plus there was of course Rias—with her huge white breasts. She is my future wife.
Now, I saw...
An unequalled beautiful crimson-haired woman. She seems to be around the same age as me or younger! Crimson hair. Is she related to the Gremory family? This woman who seems to be related to the Gremorys also has huge breasts! Thank you! That's helpful. Well, there's no doubt that she's a transcendental beautiful girl.
"Ise, we have a surprise for you," Rias told me.
We soon were all in the underground Hyoudou residence bath which was quite large. While we were all naked together, the huge breasted women washed my body all over. Whenever they washed my back, I could feel their huge breasts pressed on my back and it felt amazing! The breasts of the older ladies had a mature feeling to them, while Rias' breasts felt great too.
This was happening because Rias had offered to wash my back, and the other Gremory ladies offered to join in to help her. I was very happy and excited! How could such an unbelievable situation emerge?
Venelana-san, Grayfia-san, Chysis-san, Runeas-sama, and Rias all used their huge soft breasts that were covered in soap to wash my body all over!! Maximum titillation! Their nipples were amazing against my skin.
It was so nice that my whole body trembled. The Gremory ladies stayed close to me and used their hands to play with my body. They were running their super big breasts over my face, chest, arms, legs, back and stomach ... the erotic feeling grew more and more. Mmmhmm...
"Ise-san has such a wide back." Grayfia-san smiled. I can feel the weight of her boobs pressing down on my back and expanding!
"Ise-san, you should start calling me mother from now on, okay?" Venelana-san told me! Wow, I can call her that now?! W-Well, we are like a big family now.
First Generation Runeas-sama smiled and played with Rias's breasts. "Ara, Rias. You've grown". She really is something else.
"Now now, you must take good care while in the bath." Chysis-sama said while smiling.
The other girls in Hyoudou household do this type of stuff too sometimes, usually when Rias is present. I love it when I'm in the bath with Rias, Akeno-san, Asia, Xenovia, Irina, Kuroka, Koneko-chan, Rossweisse-san, Ravel, Ingvild, Yasaka-san, and Roygun-san and they rubbed their wet soft soapy breasts on my body. They would wash my body with their nice soft breasts, just like how the Gremory clan are right now! Ophis, Lilith, and Kunou would usually watch us as well, but they are not here right now.
This is why taking a soapy bath with a girl is great, since soap makes boobs extra slippery and soft!
"Ise, how are you doing? You hanging in there?" Rias laughed.
The Gremory clan then doubled their efforts with their breasts! I could faint by this point! M-maybe I can give them oil massages.... I wanted to fondle Rias's breasts, and her mother's, and the rest, too! To take a handful of their big breasts and squeeze and rub them down! I was so caught up in my obsession with fondling and sucking on them!
Rias's body and the rest of the girls as well were so soft and smooth, their skin so supple to the touch.... Their voluptuous breasts were too much! Did I mention their tits were huge?! I love their huge bouncy boobs!
Just then, I heard the voice of Rias's father from outside the entrance to the bath! "What is going on in here?"
Even though he didn't see us, I fainted for good this time!
