"Riku, shove your beastly dick inside big sis's tight pussy!"With both his studies and his club activities falling severely behind, Riku is basically a dropout. The only thing he has to brag about is his beautiful sister, a college student named Tomomi. One day, his club senior threatens him that the only way he's going to be in a match is if he brings his sister's panties. While his sister's in the shower, Riku steals her panties and starts to jerk off with them, but Tomomi catches him in the act. Tomomi whispers to Riku, "As punishment, I'll take care of your dick, Riku," and slowly inserts Riku's dick into her wet pussy. Tomomi is in ecstasy as Riku cums inside her over and over again.
