Has anyone fucked their step sister? Was it good?

Didn't have stepsisters or sisters. Dammit.

The only family member that I ever fucked was my cousin, Anne. I posted the story of it on here 6 weeks ago:-

"I was 16 yrs old. My female cousin, Anne, was 15. We were cycling through the woods where we lived (separately - she with her parents, I with mine) when we were stopped by 2 very aggressive women (aged 20 ?)
"Give us your bikes" one demanded. To protect my younger (& smaller cousin) I stood up to them to allow Anne to shelter behind me.
I received a slap to the LHS of my face. "Whack". It hurt, but I didn't let it show. Another one to the RHS - this time even harder.
"Oooh - I think he likes it" one said to the other, as she fondled my crotch - I had an erection ! (Cycling behind Anne, I was already semi erect as I gazed at her gorgeous arse in her very short & very tight white shorts) - but why did my semi turn into a full one when I was smacked?
"Fuck me" one of the girls (Dianne) barked at me as she lay back on the grass with her skirt up around her waist & her knickers at her feet.
"I, Er Um, don't know how to" I said (my erect cock saying the opposite)
"Sue, I think we have a virgin here" Dianne giggled. "Rock, Paper, Scissors for which one of us takes his Cherry !"
Sue lost, Dianne won, so she again lay back on the grass. "He might need some help, Sue" she giggled. I got on all 4's in front of Dianne as Sue put her hand between my legs, cupped my balls (I almost spunked at the gorgeous sensation) & guided my cock into Dianne's cunt.
It felt wonderful ! Warm & wet & very tight - better than any wank I'd had previously.
Doing what came naturally to me, I thrust into Dianne with force, withdrew before thrusting into her again. Immediately I felt my orgasm build, but I was shocked out of it by the "Crack" on the back of my head from Sue's hand - "Don't you dare Cum before she does" Sue barked. All thoughts of pleasure were dispelled by that 'Crack' - I was now an automaton programmed to obey. Fortunately, Dianne had been rubbing her Clit so hard that she came quickly.
"Phew, that was a relief - Now my turn to Cum" I thought.
No chance, Sue dragged me off Dianne, removed her own knickers & sat in front of me with her legs open. I was on all 4's once again & crawled towards Sue's 'Hairy Magnet' - my very erect young cock ready to unload. Before I got there Dianne gripped the back of my neck & thrust my face into Sue's cunt "Eat it " she barked. I did & enjoyed the taste. I must have done something right because Sue orgasmed on my tongue. "My turn now" I thought as Sue descended from her high.
No chance - "See you here next week" the 2 Strumpets said, leaving Anne & I to return home.
Before we mounted our bikes, Anne pulled me close to her, kissed me passionately & said "Thank you for saving me. You are my knight in shining armour" Corny, I know, but it made my cock erect. "Now, claim your prize, good Knight" she gasped as she lay back on the grass with her legs apart. Her knickers were soaking wet so I asked "have you pee'd yourself" She (naively?) replied "No - why?" I didn't answer. I simply removed her knickers, buried my face in her 'snatch' & licked her to orgasm. She was so turned on that it didn't take long. "Now fuck me" she commanded. I did so. I didn't last long before pulling out & squirting all over her belly. She scooped it up & drank it, winking at me. "Maybe we can fuck again sometime?", I thought as she said the same words .........
