Comic Convention Fun with My Niece

I have a cousin who has always been very cool with me.

She's around 4 years younger than me. She has an adult daughter, (lets call her Mia)

Mia has always been a little different.

Mia is very mousy and cute.

She has a smaller frame, and was on the shorter side. She could easily pass for much younger. She was also Quiet.

Mia is a higher functioning special needs. Very Mild. Most people dont know unless they have been told.

A little over a year ago my cousin called me and asked me if i still went to comic conventions. I laughed cause i had been to like 4 conventions when I was a teenager and in my 20's and she made it sound like i was always at them. I just said that the last one was before covid.

She told me Mia wanted to go but she wasn't comfortable with Mia going alone.

Although she was 18 she was very naïve and kinda innocent.

Also with her special needs she preferred to have an adult with her.

I told her id be happy to go with her. It wasnt far, just a few hours but i got a hotel nearby incase we needed to rest.

I picked Mia up and was told she had literally hundreds of dollars shes been saving on her ATM card.

She was wearing a mini skirt and cat ears. (and t shirt and shoes and sweater)

Most of the drive there she was pretty quiet but got more hyper and animated as we got closer.

Once we parked we had a short walk. She took me by the hand and pulled me along faster.

Her eyes lit up when we got inside. She seemed to konw where to go. She spent the day talking to people.

Mia kept circling back to a certain area that had more adult themed souvenirs.

Finally i kinda just stopped her and asked if she wanted something from the booth.

She told me she did, but because her bank was linked to her parents they might see what she bought. I asked her what she had her eye on. She pointed out a animal themed tail that had a way to attaching it to her body.. well not attach, but insert. It was $80. (i found out later cheaper NOT at comic convention.

still, i eagerly offered to pay for it, but if anyone found it, she bought it without me knowing.

I paid and she said she really wanted to try it on and started heading to the public bathroom.

i stopped her and told her i had a room.

In the room she went to the bathroom and came out a few minutes later with the tail kinda hanging out past her mini skirt.

She looked adorable but also sexy. She walked around the room barefoot, Swishing her ass around. She kept smiling back at me and also quickly looking at my bulge. Her last time around the room she headed right for me, put her arms around me and thanked me for her tail and kissed me on the lips.

Not gonna lie, i kissed back and slipped my tongue inside her mouth.

It was so erotic. Mia

turned around and climbed on the bed. tail in the air and meowed playfully. She circled around the bed on her hands and knees and then

she looked back at me. Mia put her face down and her ass up like a cat in heat.

I couldnt help it. i dropped my pants and got my dick inside her. She let out a soft purring noise as I pushed my cock into her wet and warm pussy.

God damn was it warm.

Once I was inside I let her warmth surround my dick. I savored it. Then I started to rhythmically pump. I made sure every inch of me came almost all the way out, till just the head was in the putts lips. Then I pushed back in. Mia kept playfully meowing while i fucked her. i also playfully tugged at her tail. i even played with her asshole with my finger. just playing at the edge if the tail.

I needed to see her B cups before I finished. So I pulled her up against me and peeled off her shirt and bra. Then I cupped her breasts and continued in my hands and continued to fuck her. i didnt last long 8, maybe 10 minutes. when i came she reached back and held my hip with her hand.

I let my cum ooze into her. Then we both laid down. She looked back at me and we kissed.

Soon we got dressed again and re-joined the Convention.

We didn't speak about it for a few months.
