Pink Chastity Cage

My sis hands me the tiny pink chastity cage. I didn't know what to do. Should I thank her like I did the panties. I muttered "thank you" while looking away. "Don't just thank me" She exclaimed "Put on the FUCKING chastity sissy." I went wide eyed. Wtf did my sis just say to me, is this ****?

I pulled down my stretched panties covered in cum. I didn't know what was the best thing to do except follow what my sister wants. After all I did just cum all over her bed, wear her clothes, and get my ass fucked by her bf like a sissy. I slipped on the tiny pink chastity in front of my sis. It was a perfect fit for my tiny cock for some reason. CLICK...and it was locked...

"So you wanna be a sissy bitch?" She asked. I responded as fast as I could "YES!" "PROVE IT TO ME! Put on this blindfold and cum like the sissy bitch you are." I took the blindfold from her hand and she pulled me on the bed. I put on this black, big blindfold. I couldn't see anything out of this thing. It was like double or triple layered. She pulled me on top of her and started to kiss me. while she was kissing me she teased my ass with her finger. Her bf's cum was leaking out as she fingered me. This had to be the extent of what she had planned.... She grabs my hips and pushes me backward. Full **** I SLAM MY CUM LEAKING ASS ON THIS HUGE DILDO. It was way bigger than anything I've ever experienced. Her bf's cum and dick both stretched me out and lubed me up to prepare me. My tiny dick swelled in it's cage, almost painful but pleasurable. I moaned with excitement, Cum leaking out of my tiny pink cage.

I start to get used to the size and it starts feeling better and better. Then suddenly she pulls me forward and hugs me THEN STARTS THRUSTING AS HARD AS SHE COULD INTO MY ASS. It was too much but I couldn't resist. "This is how sissies take it." My sis said "There's no stopping till I'm done with you so take it like a good girl." I was so turned on getting fucked by this huge strap-on. My tiny cage dick started shooting cum all over my sis every thrust. I was in heaven. The minutes felt like hours. This moment was the most sissy I would ever be. "Now flip around and ride my strap-on till you cum like the sissy bitch you are."

Excited at my sissiness I Switched into reverse cowgirl immediately. I road that fake dick like it was my life's mission. I pushed my butt back into the dick harder and harder. Something was building up. I could feel it coming along. I'm going to come sis. "Count down from 10 and cum on 1 for me sissy"
