"Yes"

With Anna pressing me like that, I couldn't refuse. I needed Anna after all the teasing she'd put me through, and couldn't bear to be left cuffed to the bed alone while Mike had sex with her right in front of me.

"...Yes." My voice, though quiet, had a pleading, erotic quality to it that even I could recognize. It was unmistakably the voice of a girl in **** need of sex.

Though my arousal stemmed from how relentlessly Anna had been teasing me, and how frantically I felt the need to thrust myself inside of her, Mike got a different impression. From his point of view, the sissy tied to the bed was squirming with desire while agreeing to obey his every command.

So it shouldn't have been a surprise for anyone that Mike took full advantage of the 'gift' Anna prepared for him. I saw Mike's body loom closer as he climbed onto the bed, straddling me and leaning down to get a better look at me from up close.

I felt squeamishness fighting with my current state of overwhelming arousal as Mike cupped my chin with one hand, giving me a friendly - but somewhat predatory - smile.

"You're a cute one, aren't you Selina?" Despite myself, I felt a thrill of delight at being called cute by my sister's boyfriend. At the same time though, I felt the urge to sabotage Mike's attempts to flirt with me...a jealous part of me wanted to make him look bad in front of Selina.

When I didn't answer Mike's question, Anna climbed up onto the bed alongside me, running one finger across my chest and neck.

"She likes it here, here and here." With a smile, Anna paused her finger to point out the parts of my body that had gotten the best reaction out of me earlier.

Mike wasted no time in following her advice, and soon I felt a pair of hands caressing me for the second time in one night. Though he wasn't as precise or skilled as Anna, Mike's hands were quite a bit larger, making me feel more frail and feminine as he began sliding his hands down my top and caressing me all over.

I could feel my body heating up with pleasure, but tried to hide it, biting my lip to keep from letting out a soft girly moan.

Leaning his face close to mine, Mike tried to gauge my reaction while he persistently rubbed his thumb against my overly sensitive nipple. "Does that feel good, Selina?"

From the side, Anna pressed her lips to my ear, her breath tickling me as she whispered, "tell him the truth."

I wanted to deny his skills at fondling me, but disobeying Anna was something I'd been having a harder and harder time doing recently...
