Dan prefers to watch the two girls a little longer

My voyeur instincts prevailed and I decided to let Liv have her way with Katie.

Liv gave Katie a few more really hard slaps on her upturned ass which was by now again gleaming in an angry red. Then, Liv hopped on the bed, her strap-on swinging obscenely from her crotch. I thought she would now start mounting Katie, so I was surprised when Liv got in front of Katie. Mercilessly she grabbed a good deal of Katie's hair and yanked her head up. "Nnngh..mppfh!" Katie protested in pain, but there was no way she could fight Liv's grip.

Liv grinned mischievously and playfully leaned her rubber cock against Katie's cheeks. The tied up girl winced at the touch and shuddered.

"Can you feel this, Katie-slut?" Liv cooed. "I'm gunna ream your tight ass with this magnificent cock of mine. You will like this, don't you?"

"Plmmphh...nnfghh..." Katie moaned through her ball-gag.

"I don't hear you bitch," whispered Liv menacingly.

Katie struggled in her bonds, trying to wring her hair free of Liv's grip, which just added additional pains to her misery. "NNffffhg...mmd lrrzt grrmpf" Another sob shook Katie's slender body.

"I think you really need it good, honey!"

Liv grinned. She really enjoyed her power over the helpless girl. My, Katie had really made a bad pick... from her viewpoint. I couldn't say the same, of course.

"But," Liv continued with a mockery of a good teacher's voice, "I'm in a giving mood, so to say. Therefore I will give you a choice. I will briefly remove your ballgag, bitch, and then you can tell your mistress, which hole you would like to have filled with my big brother here. If you convince me that you really want it there, I'll make it easy for you... maybe. If not..."

"Mmmpsdff" Katie moaned in between with pleading voice.

"Well, I see you get the point."

Liv let go of Katie's hair and undid the ballgag. Katie first coughed and virtually spit the plastic ball out, sending a good deal of spit onto the bed. Then she took a huge amount of air before she spoke. I was curious to hear her reply.

"M...m-my ass" Katie whispered almost impossible to hear. "Please...f-fuck my ass...mistress."

'Wow' I thought to myself and my hard cock jumped to life as I heard Katie's choice. Either we had discovered a new favorite sex practice for Katie or she was really getting into her new position as my - Brian's - sex **** and tried to mollify us by trying to second-guess our preferences and make appropriate picks so that we might do easier on her. Liv seemed similarly surprised, but quickly she resumed her dominant composure. "Good, ****. Now I want to hear that you really need it."

Katie sobbed, but she had no other choice than to accept her fate. "Fuck my ass. I...I need it so bad. Please."

Liv gave her a light tap with her open palm to her cheek. "Louder, girl. I'm sure Master Brian wants to hear you too."

Katie winced, but did as ordered and continued with hoarse but nevertheless surprisingly sensuous words: "Please, mistress. F-fuck my ass. I've been a naughty girl. I d-deserve to be spanked and I really need to feel your mag-magnificent cock in my ass. Oh, gawd...please!"

With the final words her voice had ebbed down to a hushed whisper. Liv patted Katie's head and said "Good girl. Now there's a very good girl." Katie sobbed and her whole body shook. Liv then reinserted the ball-gag between Katie's trembling lips despite her feeble protests. When it was secured again, Katie resigned. Without being orderered she placed her head down on the mattress, thus raising her sensously twitching ass even more.

Liv grinned at me while conducting a stroking movement with one hand over her artifical cock. She looked at my raging hard-on and said teasingly, "Keep your sword well honed, friend. You'll need it soon!"
