Donna

"I'm going to borrow your girl now, sis," you announce, "You'll like what I have in mind though."

You go over to Donna and stand her up. You walk her over to the body pile that is Candace bound spread-eagle in a chair with Mrs. Tan's face buried in her pussy as she is on her knees doggy-style in front of her.

You whisper in her ear what you have in mind and she nods happily.

You lift her up and set her on the Teacher's back, her body now **** to hold up more weight on her knees. She lays out across the woman who wronged her and raises her legs up. You grab them and guide your cock towards her pussy.

With her recent orgasm, she requires no more foreplay, so you thrust right in!

"Shit- so full," Donna exclaims.

As you slowly start to fuck Donna, you notice that you don't hear any noise from Candace.

"Nobody told you to stop licking her," you say, slapping Mrs. Tan on the ass very hard.

She issues a muffled response and you can then see the results on Candace's face. She smiles at you as her sensitive pussy is getting more attention.

Satisfied, you start to pound Donna's pussy harder and faster. First, it is for her pleasure. Second, it will make her move and shake more, punishing Mrs. Tan! Regardless of your motivation, she loves it!

You get a real surprise a moment later when Donna leans her head back and upside-down kisses her friend Candace! You didn't tell her to do that...but you certainly won't tell her to stop.

The action keeps going as your Sister watches on- you don't check on her at this point- and everyone is happy. Well, except for Mrs. Tan- who you occasionally spank for fun-, but who cares about her?

After several minutes of excitement and fun, the girls are close to cumming.

"I'm gonna cum soon," Donna says, "May I please cum, Master?"

"Me too. May I please cum again," Candace asks.

"Hmm. What do you think, sis?"

You glance back at your Sister and find her holding something unexpected...
