Yes

I decided I didn’t have much choice, removing my pants and boxers. Ella smiled at me, nodding in a manner that seemed both encouraging and demanding. As I slid the girly underwear up my shaven legs, the lace tickled me lightly and elicited a strange response from my body. The panties were strangely delicate, like nothing is ever felt before, and they rested tightly around my cage.

“You look so cute!” Ella had a giddy excitement to her as she observed me, enjoying how feminine my body looked between the panties and being completely shaved. “How do they feel? I bet you love them!” She teased “They feel really weird, kinda soft but also a little tight” I said “This is really embarrassing, Ella, can I take them off now?” I asked, humiliated “You’ve only just put them on!” She giggled “Leave them on” her tone sounded a little more demanding this time. Swallowing my pride, I left the panties on and put the rest of my clothes back on, putting my boxers in my bag. For the rest of the afternoon, we played games as we usually did, only this time with a mix between Ella teasing me about wearing girly underwear and encouraging it. Strangely, this mixed response provoked my dick to try and get hard in its cage, causing me even more frustration and embarrassment.

When I got home, I went through the usual routine of having a shower (this time being very careful as to prevent Jessica seeing that I was wearing her panties) got changed into my pyjamas, ate dinner and got into bed. As I lay in bed, I tugged on my cage, trying to take it off but instead I found only frustration. It took a while, but eventually I fell asleep, the image of my caged cock tightly nestled into a pair of my sister’s pink, lacy panties ingrained in my mind.

The same frustrating feeling of my dick straining against its cage woke me up again, and this time I decided to just ignore it as best as I could, heading straight to the shower and getting dressed.
