A few weeks ago I had to move back in with my older sister. We are both in our late 30s. I swear we were mixed up at the hospital because where I am athletic, lightly built frame, she’s about an inch taller, pear shaped, fat (over 370 pounds) and a bit plain, almost pretty if she gets herself all dolled up. Anyway she’s never really amounted to much professionally, but she’s a pretty good artist. On the heels of my divorce my credit is destroyed and I needed a place to land. She opened her studio apt up to me.
At first it was just the awkward trying to stay out of each other’s way. But then she decided she wasn’t going to go into the bathroom to change anymore, and soon after I stopped too. One night I got out of the shower and was looking for some clothes, digging through my laundry basket. When I found my drawers I just let the towel slide to the floor and my sister just stared at my naked body. She said I HAD to let her sketch me. Naked. I shrugged and agreed to let her.
So there I am butt ass naked while my sis does a quick pencil sketch. It took her about an hour or so. She yelled at me to hold still a couple times and I told her I’ve never modeled so just be glad she gets to have someone to sketch.
When she finished she showed me her work and I thought it was amazing. I was still naked. She touched my p**** and said it was beautiful. I agreed and started to get dressed but she stopped me and asked if there was any way she could “thank” me for my modeling “services.” I laughed but she persisted and said she would give me a hand job.
Keep in mind I haven’t had s** in a while so I agreed to let her. But after she started she asked if I wanted to up the ante and put it in her butt. I said no and that was too much but she countered I was basically just using her r***** to m*********. So next thing I know my sister’s massive panties are coming down and her big bare ass is begging me to dominate it. She handed me some lotion and I put some on my d*** and her a*** and slid in.
I don’t know what it was about that moment. The taboo maybe. But f****** my f***** sister up her fat ass was better than any of the p**** I’ve ever had.
I blew one of my biggest loads ever in her ass. It felt so good. When I pulled out a small amount of p*** covered my d*** and I didn’t even bother to wipe it off. We just lay there about 30 minutes before she said she couldn’t believe it just happened. I laughed and asked if she was hungry (as fat as she is she’s always hungry) and suggested we go get some dinner. While we were out the shame of what we did set in. We went to a place where I usually flirt with the waitress but that night I couldn’t. I had just f***** my own sister up her ass and still had her s*** on my d***. It felt so wrong and shameful.
But that night she asked if I’d sleep in the bed with her instead of on the floor. We both lay naked, spooning each other before finally she said she wanted to do it again.
So I did. And have done it every night since then. I’m horrified what my ex wife would think if she found out but at the same time I want her to know my sister’s fat ass is way better than her p**** ever was!
What the h*** is wrong with me?
