As soon as I saw my sister-in-law, Jillian, standing there, video camera in hand, my dick goes limp and I felt myself start to sweat. It would be one thing if she freaked out – after all, she did just come home to find me in her bedroom, wearing nothing but her panties, jerking off into them. The fact that she wasn't freaking out, but instead waltzed across the room to her bed as if nothing untoward had happened, was unsettling.
She put the video camera in the top drawer of the table beside her bed. The drawer with the lock. "I have to say, John," she said after a moment of uncomfortable silence, "I really didn't know you were into wearing girl's panties. Hey, do you think my sister knows?"
My eyes went wide, and I could feel my heart start to beat faster. "You wouldn't." I immediately started to think about how my wife would react – she's a very conservative, vanilla lover, so I can only imagine it would not be a good reaction in the slightest.
"I wouldn't?" she said confrontationally. "Are you sure about that? Because I'm pretty sure I would." She smiled as she spoke, crossing her legs sultrily. "I mean, why wouldn't I?"
I tripped over my tongue trying to spit out a reason before finally saying "It wold break your sister's heart!"
"You really should have thought of that before you started jerking off into my panties, John," she said flatly. "I mean, god, the front door wasn't even locked; it's almost like you were trying to get caught."
I could feel myself getting red. "This is going to cost me, isn't it?" I finally said, broaching the subject that we were both thinking of.
"More that you could possibly realize," she replied, her smile widening. I hated her in that moment, and yet she looked so sexy, so in control.
"Let me go get my wallet, it's downstairs," I told her.
"Oh, don't be silly John, I don't want your money," she told me. "No, this is going to cost you in other ways."
"What do you mean?"
"Well, for a start, I want you to stop hassling me about paying rent and getting a job during the summer, because I'm sick of hearing that shit from you."
"Done," I said. Given how ineffective my hassling her had been, this seemed to be a small price to pay.
"Your real repayment, though," she said, uncrossing her legs, "is that, for the rest of the summer, you are going to become my plaything, unless you want my sister, your wife, to see this little tape of mine."
My eyes went wide again as I processed what she was telling me. Jillian was a hot little piece, but I had never cheated on my wife for as long as we'd been married – and cheating with her sister would be the ultimate betrayal. But what choice did I have, unless I wanted her seeing the video? At the same time, though, wasn't I just putting myself into further jeopardy of being blackmailed if I agreed to this?
I realized it had been a long time since I'd said anything. "Your plaything?" I stammered out, not knowing what else to say. "Like, sexually?"
"Of course, sexually, silly" she said, the sultry smile suddenly getting exchanged for a more innocent-looking one. "There's a bunch of stuff I've been hearing about from girls at school, but haven't had a chance to try out myself. This should be a good chance for me."
