When Jack took Evelyn back to their house, Evelyn couldn't bear the poison in her body anymore and let out a painful and lewd groan.
"What should I do?" Lisa had no idea what to do now. All her hopes were on Jack.
"Brother, I... I miss you!"
Evelyn said as she put her arms around Jack's neck. Her breath became heavy and hot.
"No, Evelyn... We are brother and sister. No way!"
Jack tried her best to hold back his sexual desire and keep his last sanity, even though his penis had already been erected.
"Brother, I know you are not that Jack. You come from another world. Help me, brother!"
Evelyn reached into Jack's crotch and grabbed his penis.
"Lisa, what should I do?"
This was the first time that Jack felt helpless. He looked at Lisa, hoping that Lisa could give him some help or advice.
"I think... You should promise Evelyn that you are not her real brother. She needs you!"
Lisa blushed. After all, such kind of thing was shy and exciting.
"I... okay!"
