They both looked exhausted."I told her about Kim," Shari told me. "Tanya and I are old friends. Heck, she's my cousin." If you can't keep it in your p...nts, keep it in the family," I said."That's terrible!" Shari giggled. "Besides, she's like a second cousin."Tanya shook her head."No, I'm your fist cousin. My mom and your mom are sisters," Tanya said with a wicked grin very reminiscent of Shari's when she was being really 'bad.'"Incest," Tanya said, smiling at me. "A sport the whole family can.
