Clothes were no longer an issue with Chris and me. I got the coffee started.A few minutes later Chris joined me.“You’re up kind of early aren’t ...ou?” she said. She was wearing panties, but no top. Her big, beautiful tits were there for all the world, or at least for me, to see.“Yeah, I decided to get an early start today.”Chris poured herself a cup of coffee, sipped a little bit, then sat down across from me.“What’s so important that Mr. Stay-in-bed got up before me?”Looking at my sister. I know how fragile and delicate a woman's psyche is. My poor sister was probably in that shower, right now, (and had been for hours) crying her eyes out and trying to scrub the degradation, of what I did to her, off of her body and cleanse her soul.God, I thought, pulling the sheet up to my neck and shrinking in the bed, how was I going to face her now? How was I ever going to face her again? I'd had such a loving relationship with her for all of these past years and now, in one, lustful night,. My wet pussy was pressed firmly against one of his thighs, as he rubbed his thigh between my legs, teasing me. I could feel my wetness leaving a growing spot on his jeans, and knew that was precisely what he had intended. And suddenly he pulled back. With a devilish smile he told me to get dressed. He whisked my panties out of my hands as I was about to put them on and told me that I was going to class without wearing any undergarments. I tingled as I realized the implications of this. Would. That first time I tried to be sly about it, to get him to make an offer of some kind, but he played dumb until I basically stripped and climbed up on his desk. Then he knew what to do, and has like every afternoon since. Mr. Renfrew fucks me pretty good, and he always cums inside me, without protection. That's not my problem, either (although when I asked him if he was scared I might get pregnant, he told me that was my problem, not his). It's not my problem because my stepdad pays for my birth.
