You fuck with a captive audience.

Natalia pretends to be scared.
She pretends to hate this.
She pretends to hate you.

As you enter her pussy and fuck her, she's in love!

She's always wanted to be fucked in bondage.
Years back, she was robbed, stripped and tied by a burglar.
He seemed to be setting her up for this...

...but then he didn't fuck her! What a jerk.

She also had the aphrodisiac in her gag, but needed it far less than Natasha.

Speaking of the busty beauty, she's watching this and getting turned on.
She's new to bondage (unless she's been taken this way before and just had her memories erased!), but not new to voyeurism.

She had a kinky roommate in College, who always got guys to fuck her while Natasha was 'asleep' in the room.
Did she return the favor?
Once or twice (or a dozen times- who's counting).

Natalia cums three times before you shoot your load in her pussy.
She acts upset, but loves it.

You get up and check Natasha.
She came too!

Hopped up on the drugs they gave you to keep going nearly non-stop, you pick Natasha up and take her seat.
You make her ride you (testing the chair's durability!) as Natalia looks on.

You told her to, of course, but she was going to anyways.

Natasha cums twice from this before you shoot a second load in her pussy.
She doesn't know that she's impossible to knock up right now, so she's really nervous after taking two loads already today!

You sit her back down and tell them you'll be back for more in a bit.
