"Yes you are, sis." Megan's brother, Jack said, as he wrapped his arms around Megan "Jack, you flatter me." she responded, turning around and giving her brother a deep kiss. This was by no means odd, brothers and sisters loved each other after all, so of course they would show their affection.
Jack began to show even more affection to Megan as he began to grind his hips into her, rubbing their dicks together "Jack, why don't we continue this in the shower?" Megan stated, "I don't care either way, but if that's what my sister wants, then so be it." he responds, making his way to the, VERY large shower.
Megan turned on the shower, Jack shivered at the cold liquid hitting him "Tad cold, don't you think?" he said "Lets warm it up then." Megan responded, continuing the grinding, while rubbing both dicks up and down, with her hand. In spite of the cold shower, they were both rock hard, and soon began speeding up.
Grinding together their dicks, which were vigorously rubbed up and down, up and down, by Megan's expert hand. Jack played with his sisters double D's, as they gave each other a deep passionate kiss, which muffled their incestuous moans. In just a few moments more, they climaxed, a gallon of cum, maybe more, coated their bodies, and not quickly swept away by their shower "Your first cum, Jack?" "Saved it just for you."
