Making Out

Several days had passed since my sister and I became lovers. Ever since that day, I had been having intimate relations with her as well as a lovely threesome together with Mary. She allowed me to do hee again after we exchanged gifts. 

Sister seemed not to be affected that much as she saw me banging on her lover, so I kind of believe that she really wanted it. She was even pleased and playing herself every time we fucked, making me think she was developing a particular kink. 

The new sword and the skill were not the only things I had given her; there was also a promise that we were about to grant tonight. 

"You seem excited, Sis." 

"Of course I am. But I am nervous as well. I am going to do them after all."
