No, go to bed

“I guess I’m kind of tired,” Susie admitted. “Help me clean up first?”

“Sure, sis,” I answered. I tried not to sound disappointed. But after such a sexually charged evening, I had kind of been hoping I might get some real action. When her three girlfriends left, that left my sister as my only hope. But apparently that wasn’t going to be either.

It didn’t take long to clean up, just some glasses and bottles in the living room and what had been left on the kitchen table. I rinsed things off and Susie put them in the dishwasher. I wiped down the counters and we were done.

“Thanks for a fun evening, sis,” I told her as we left the kitchen. “Did you enjoy your birthday party?”

“Oh, for sure,” she replied. “It’s just been a long day. I’m pooped. Guess I’ll head on up to bed.”

“Ok, I understand. I’ll be right behind you.”

And I was, literally. She went up the stairs first and I was just a few steps behind. Unfortunately, that left her tight ass swinging in my face and all I could see was the word ‘PINK’ on her tight gray shorts. I felt my hard-on, which had finally subsided after the girls left, start to rise again.

My sister’s room was the first one on the right and she paused as she opened the door to go in. “Well, it’s been fun, bro,” she turned back toward me. “Good night.”

She put her arms out toward me and I wrapped her up in my arms and hugged her tight. I gave her a big kiss as I fondled her ass. My hard-on rose a little more, but after a few moments she broke away and went on into her room and closed the door. I went on down the hall to my room, which was the next one on the right. I went in and closed the door and threw myself on the bed. It was almost a kind of **** knowing my sister was just on the other side of the wall probably getting naked.
