Things were a bit awkward in our house for a few days after I’d fucked Susie for the first time. I think we were both embarrassed by what we’d done and I felt guilty as hell. She might only be a step sister but it was still wrong, if our parents ever found out what I’d done to her they’d have killed me for sure.
So we went around the house doing our best to avoid each other. To be honest I didn’t trust myself to be alone with her, after that session we’d had if I was being truthful I was hungry for more.
A couple of frustrating days passed and I took myself off to my room early one night. I was asleep but in my dream Susie was there pressed against me, stroking my cock and playing with my balls. I woke suddenly and realised it had been no dream, Susie really was there, in my bed alongside me holding my now hard dick in her hands.
“Jesus Susie, what’re you doing?” I gasped, shocked at finding her there.
“I couldn’t sleep Danny,” she whispered back softly. “You don’t mind do you? I’ll leave if you want.”
Leave? No way was she leaving. I put my arms around her and pulled her back closer to me, she was naked with not a stitch on and I was aroused and rock hard for her.
We ended up screwing that night and every other night that followed. After everyone was asleep Susie would creep quietly down the hall to my room and get into bed with me, going back to her room in the morning just before our folks woke up. My cock had never had such a great work out, I was getting it every night from my horny little sister.
One thing bugged though in this otherwise perfect set up. I wanted to give it to her up the ass, I wanted it badly. But Susie was one helluva tight girl, her pussy was still quite tight despite the pounding it got from my cock every night, but her asshole was almost impenetrable. We tried a couple of times to get my dick up there, but I was just too big for her and it would end with her in tears and I’d feel so guilty we had to stop.
She’d do loads of things to make it up to me, sucking me off, giving deep throat which in itself was no mean feat given the length of my dick, doing little strip teases for me in my bedroom.
One night I knew I couldn’t stand it anymore and I just had to get my cock up her ass. She had done a raunchy little strip act for me and had turned around naked to face the wall, bending over at the waist. With both hands she grabbed her ass cheeks and pulled them wide apart giving me an awesome view of her pussy and asshole. It was too much for me and I shot my cum all over my hands and the bed.
She turned around grinning wickedly, “Oh Danny you made a mess of yourself.” I sure had and made her come over and lick up every last drop of spunk.
I had to ride her ass I couldn’t stand it anymore.
The next day I went online and found a site selling sex aids. Butt plugs. Why hadn’t I thought of that before? I figured if I bought a few in different sizes maybe Susie’s ass could be “trained” to take my cock.
So I placed an order and about 5 days later the package arrived. I ran up to my room with it and scattered the butt plugs onto the bed. The smallest was really thin, not much wider than a finger and I knew she could probably take that. There were four of them in all, the biggest being a fat one measuring around 2 or 3 inches and about 5 inches long.
That night when Susie came to bed she got a little surprise. I got her to roll over and inserted the smallest butt plug up into her ass. As I’d thought it went in easily enough.
“What’s this for?” she asked surprised.
“Just keep it in there sis, leave it until tomorrow.” I told her. The thought of her sleeping all night with that thing up her ass turned me on and I had to give her a quick fuck up the pussy although it wasn’t really what I wanted to be doing.
In the morning she got up and went to go back to her own room.
“Leave it in there,” I reminded her as she slipped out of my bedroom.
“But it’s sore when I walk Danny.” She complained, “How am I supposed to go to the toilet?”
