Your sister

After a brief pause, Taylor suddenly launches forward and impales her mouth on your cock, starting to suck it eagerly. You smile as you pat her head then look towards your mother, who is looking on in fear and disgust.

"Taylor! What are you doing!? Stop that now!" Your mother shouts.

Your sister pulls her mouth of your cock and looks towards her and says "I'm sorry mom. I don't know what's got into me... but it feels so good."

You then say, "Do you want it in your pussy Taylor?"

She looks back and just nods. You then pick her up, bend her over the desk and shove your cock into Taylor's dripping twat. As soon as you bottom out your sister screams in pleasure and instantly orgasms. You turn around and look your mother in the eyes before you start slamming into Taylor, maintaining eye contact with your mother. To her shame, and your amusement, your mother moves her hand between her started to rub her pussy.

"Hey sis, look at mom," you request of your sister. She looks back over her round bum and smiles at Charlotte, a wild look in her eye.

"It looks like she's enjoying the show. Let's give her something really erotic to look at. You thinking what I'm thinking?"

"I think I am..."

You pick her up so her body is on display and your dick can be seen very clearly going in and out of her pussy. You then turn around to show this to your mother who picks up speed on rubbing her wet snatch. You figure that it's best to finish with Taylor so you can get to fucking the luscious body of your mother.

You shoot your cum into her snatch and decide that you just want her as mindless fucktoy with some of the usual improvements, and save the real fun for your mother. You command your sister to strip and join the other slaves outside. She hastily obeys, leaving you alone with your mother who fearfully awaits what you have in store for her.
