They have fun together

Emma was too interested in the subject, so she asked Hannah if she could touch her dick, receiving a positive response afterwards. She came over and looked closely at her sister's cock, even finding her vagina behind her balls.

Emma got excited and started sucking Hannah's cock, while she started playing with her cock, which was hard again.

Hannah, seeing Emma playing with the two dicks alone, took her own stick out of her mouth and told her to lie on the floor. Emma obeyed, and then Hannah lay on her in a 69 position and started sucking each other's cock.

Emma took advantage of her free hands and used her fingers to stimulate Hannah's pussy, which did the same to her. Soon the two came and tried to swallow each other's cum, but Emma didn't expect Hannah to shoot more cum than she did and she couldn't swallow it all.

Recovering from orgasm, Emma asked "Hannah, if you and Mom already had dicks and knew that one would probably grow in me, why didn't you ever tell me?"

"Mom said it was best not to say anything so as not to make you insecure."

Hannah said. Then she got up and left the room asking Emma to follow her.
