They are to the point. Better description about her orgasm (pussy clamping down) and his, with him feeling the spurts shooting from the glans), but how about WHERE he felt it first? Always starts at the lower back, then the guy might feel the sensations at his toes, leading to the cock stiffening and contracting once involuntarily then the first spurt shoots, but how many every spurts he normally has. Don't be afraid to describe them and to include that detail at least.
May this relationship prosper. My second favorite type of incest.
Very nice series up til now, and very believable, but slowing the pace a bit and adding more detail of the siblings feelings and responses would make things more exciting.
