Don't make me cum alone...! ～Darkness, sibling futon mingling

They covered my mouth with their hot tongues... they played with my tender secret parts... my two brothers would not let go of me until I came...!
Even now, the three of us three siblings always sleep together in the same bed. Because our parents are not at home, the bond between siblings is stronger.
But I...broke the bond between siblings because of my love for my eldest brother Ryu.... When I kissed my sleeping brother Ryu, my second brother Rei saw me kissing him....
What should I do if I want him to shut up? Rei stroked my body with his rough and gentle hands... Ryu, who didn't know what was going on, intertwined his tongue with mine... The three of us were under the covers side by side... He made me cum again and again...
