She opened her mouth and pressed her tongue against the girl's slit.She was rewarded by a similar gesture from Crystal between her own legs. Kari gasp...d again at the sensation. It was absolutely heavenly! She spread her legs to give Crystal plenty of room to work.Kari brought her hands up and placed them on her little sister's pussy lips, which by now were so wet that they almost dripped in her face. She spread them apart and drove her tongue inside. Crystal gave a startled squeak and her whole. My dad was speechless. He was also upset."Infantry?!" he said, like he was pronouncing my doom. "You let them put you in the fucking infantry?"I had never heard my father curse. Not once. I would later realize he had the full vocabulary every soldier has. He just didn't use it. He had left that life behind, when he started a new one. That's when I found out he had been in Army Intelligence, and had one of those super top secret if-I-tell-what-I-did-I'll-have-to-kill-you jobs. But it was too. There was a knock at my door."Come in." I said.It was my Dad, "Hey Bud, your Mom surprised me with tickets to the game tonight. You mind if I put off fixing your sister's window until tomorrow morning? I'll move her bed in here for the night so you two won't have to share." Um, um, sure, that sounds, uh, fine..." I stuttered."Thanks Bud, I owe you one!" my Dad said exiting my room.My mind was now working overtime, hoping that last night was not a dream.I had to do something, I had to talk to. But, before I could answer, she opened her door and hopped out and sashayed to the door.We all finished eating a late dinner and sat around talking some more. There were questions about places I’ve been in the military and what I was hoping to do in the future. We talked about what was going on with my sister and my other cousin Tina.About 11pm my mom, aunt and uncle decided to turn in. My sister was talking with Cara for a little bit and Tina and I were exchanging stories from her summer trip.
