Sister seduces tranny brother for sissyfication

As I massaged her bum cheeks spreading them I thought FUCK IT & started kissing and tonguing her bum hole. I removed her knickers. (((Put em under cushion for later teehee) )
She also somehow managed to have pulled down my pants and her feet were wanking cock which was harder than its ever been & a I my tongue was so far up her arse that my lips were french kissing her hole my cock felt as if it would blow my knob off.
Then it did my spunk shot all over her feet & I was shaking as the most intense orgasam I've ever had seemed to last for ages.
My sister turned over onto her back & as she was ordering me to remove her spunky holdups she open her legs revealing a triangle of trimmed Pubes which exposed her pussy lips and clitty
She spread it and said " my turn to cum lick this it makes me orgasam it's my clitty
I Soon got the knack after she showed how, my cock hard AGAIN soon her breathing got heavy & as she began to whimper I teased her slowing my tongue action down this somehow got her screaming in a delightful tone of sexyness Then I felt it, her clitty throbbing I matched its beat with my tongue strokes. She came hard. Made me stop it was so intense
We kissed as she stroked my hard cock, spreading her legs for me she put it in herself and my cock slipped in easy her pussy soaking. I was so turned on I came in seconds shooting my spunk up my own sister's forbidden pussy. Which made all the more intense
She laughed at my premature ejaculation 30 seconds of it
As she put on her dressing gown she said " You were good at cunny, & I only cum like that anyway." & as she kissed my cheek she handed me her knickers, and nylons and whispered you should have these I know you are tranny and I want u as my sissy" I heard myself reply "Okay!" As she left for bed she said "I give u some of my old bras, & knickers oh & I've a lace body too. And dont worry I've plenty of tights too! !"
I sat on sofa in only a tshirt and raging hard cock again....So I put on her nylons & knickers and wanked over what just happened & got another boner as I lay on sofa in all the clothes she'd worn out, spraying her tarty perfume over me and wiggling my arse as I paraded about imaging what was going to happen next.
