Do it again." I did as she asked but this time really put some effort into it and my cock jumped so much that the panties slid off it. "Mmm," she said... "you are a big boy aren't you Mike." Now I've never considered myself big, but looking back I suppose eight inches was on the well endowed size for a sixteen year old and her compliment made me feel good. I began to show off now, flexing my stomach muscles and making my cock jerk violently.Mrs. Evans scowled across at me. "That's enough messing. But she seems like a wonderful person.’ ‘You say Cormac did the same thing to you?’ ‘Yes. Pretty much. Not in front of the whole cast and crew though, thank God.’ Up by the stage Cormac was clapping his hands to restore order. Lexi was out of his range though and had escaped his line of fire. She caught my eye. She held up a finger indicating that she needed a minute to collect some things, then disappeared backstage. She didn’t look devastated and I was somewhat surprised. I turned back to. To see if see could see my cock I faked a “I’m tired” stretch backwards so I could kind of push my cock out a little more, which it did, and sure enough her eyes went right down to it and widened. Then she looked back up to me with a little grin and did a little stretch of her own with just one hand behind her back as her other hand “accidentally” unhooked her halter top string and one side of her top dropped down exposing one of her tits. With a little “oops” and a smile her finger slip into. You, you can't!" Jared blubbered now totally confused as his confrontation at catching us in the act had totally come apart on him."And why not?" I now asked him still teasing my daughter's spit with the head of my cock, though not quite putting it in yet."Because ... because, because she's my sister for one! And ... and ... she's your daughter for hells sakes!" He barked."So? Aren't you currently fucking my wife? Your mother?" I asked inquisitively, taking delight in the expression of his face.
