When I got home she was taking a nap so I woke her up. Then told her I had to shower before we left, so I showered with the door open but she didn’t come in :(

I was free balling in a pair of gray basketball shorts and I asked my sd if she could go inside the store and try to buy smokes for me if I handed her money. She said “why can’t u go in?” I said “because I’m not wearing any underwear under my shorts and my dick is really visable.” I had put my hand and gripped it in my shorts and she looked down and said “oh wow - yeah” Then she said, it must be really inconvenient to be a guy with a dick getting hard all the time “
Then she sajd “if you woke up and we’re a female, what’s the first thing you’d do?” I said play with myself and taste myself. Then she said , “yeah I would definitely do the same thing”

By the time we got home it was later and her mother and I usually have her give us her phone at a certain time so she doesn’t stay on it all night. I sent her a text that said “phone please”. I was changing in my bathroom with the door open. I took my shorts off and put on a great pair of small thin gray boxer briefs that allows for a HUGE visible bulge. She walked into my room and as she walked by the bathroom looked over and saw me in my boxers with a huge hard on. She immediately looked down at it, and paused to check it out. It turned me on even more. She said “Jesus” and covered her eyes. I replied innocently “I have clothes on wtf”

Then she said -“that’s huge”and followed me into the bedroom and sat on the bed

I layed down and she literally sat on the foot of the bed and I grabbed her by the waist and told her I wanted to take a few pics with her. Then she said let me see the pics and she still didn’t see the dick pics I had hidden in my folder.

Then my sd looked at one of the pics we took and she started editing it. I asked what she was doing and said cropping it so your giant dick isn’t in the picture The front door opened and her mother had arrived home
