It’s a trap.

When Matt opened the door, his sisters rushed him. Ann grabbed the pen out of his hand as Becca pinned him against the bed. “What are you doing?” He asked as he tried to break free. Seeing his sister look at the pen and then back at him with a sadistic look in her eyes he said. “No don’t write on me with that.” He thrashed as she grabbed his hair and held his head still putting the pen against his skin.

Ann smiled as she wrote Becca and Ann’s breeding stud on her brother’s forehead. Seeing the ink vanish she frowned and threw it away a little disappointed. Suddenly Matt stopped fighting them as his cock got hard. Without warning he grabbed Becca’s hips and twisted her around. Becca looked back in surprise as he lined himself up and penetrated her making her moan in pleasure. “No fare.” Ann said pouting at her sister. “It’s my turn.”

Matt’s mind was filled with only one thing. He needed to impregnate his twin sisters. It was his life’s goal. Thrusting into Becca as fast as he could he was not going to last long.

Sensing her brother was getting close Becca tried to pull away saying. “Stop. You better not cum inside me.” Her brother would not let go his hands firmly clasped around her hips. She looked to her sister for help, but it was too late as their brother groaned and blew his load inside her. She cursed as he let her go and she sat on the floor looking at the mess he had made inside her.

Ann backed up seeing the look on her brother’s face as he stood up and approached her. She backed into the dresser and he grabbed her throwing her on the bed. Before she could get up he was on top of her. He put a hand around each ankle insuring she could not get away as he slowly penetrated her. “What has gotten into you?” She asked as her brother started to aggressively thrust in and out of her.

“Must breed sisters.” Matt groaned trying to achieve his goal as fast as possible.

Thinking about his change in appearance and how he was acting now, Ann realized it must have something to do with the pen. “Get the pen. It has something to do with all this.” She told her sister pointing to were she had thrown it. Becca looked at her and sighed getting up to get the pen. Picking it up off the floor she walked over to the bed and looked at her sister. “Well don’t just stand there write something to make him stop.” Ann said demandingly.

Becca looked at the pen and then at her brother and sister a smile slowly spreading across her face. Taking the pen, she knew exactly what she wanted to write.
