she snuck into my bedroom

"i can't believe that such a pretty girl is licking my!"my childhood friend ryou has transformed into an exceptionally beautiful woman. the first time i saw her all grown up, i was so instantly lovestruck that i nearly felt like a man and right now, that very same girl is creeping into my bed!? try as i might stop her, her slender, delicate fingers wrap gently around my body, causing me to moan with pleasure but isn't this wrong!? we're both women! i want to resist, but my body won't listen to my brain. and just as i start to wonder what i should do, she pulls something out from her crotch and utters the words, "i'm putting it in." wait. putting it in? putting what in!? ryou, don't tell me you were a boy all along!?"
