Sabrina was happy to see that her sister was enjoying herself. She had wondered what Luna would feel when she was with a boy. She watched Luna rock on Ken and come and she shuddered. She saw the disapointment at the site of Ken's disapeering cock and felt Luna's warm wetness on her hand. She wanted to see Ken fuck Luna later alone, she was going to have to give him the draft, he would be drained after this and she wanted to see him with both girls seperately.
Giggling at Marina's enthusiasum, she cupped Luna's pussy with her whole hand, feeling the come leaking out of her dripping quim. After rubbing her slit, she slide a finger up inside Luna as she came hard. She knew that Marina was riding Ken's true cock in the middle and she was close to coming herself. Arching her back, she let go and fell over the edge, feeling the cock inside her shirvel just like it had with Luna.
Pulling her baby sister over to her, she pressed her longer, lanky body against Luna's petite body and left Marina alone to fuck Ken. She grinned at him, then turned her face and kissed her sister, her finger still buried inside of her, her thumb of the same hand rubbing her clit. She wondered what Ken would do now that he could move more freely.
