Hot stepdaughter

I married Lynn about 5 years ago.
She was 55 and I am 60. After she moved in, her 20 year old stepdaughter Kelsey came home from college. She was about 5 8, long brown hair, big hips with a matching ass, medium-size breasts, probably a C cup, and puppy eyes. She was good looking, but not hot, but sure sexy as hell to me.her real dad was a total prick and she definitely had daddy issues. She loved dated older men and often revealed she was attracted to the "father" figure. I tried to be that to her and she was very open and candid with me about her life even though we had just met. She even told me she had just lost her virginity to some boy she knew from high school!
Her mom was gone on a girl's trip one weekend so it was just the 2 of us hanging out. I got up that Saturday morning and just doing my regular thing and I knew Kelsey was asleep so I tried to be as quiet as I could.
About 30 minutes later, I heard her door open, and she comes out wearing a large tank top which showed a lot of side boobs, and I assumed panties underneath.
"Morning daddy" she giggled." " Morning baby" I laughed back.
She walked around kitchen making sure I got a great shot of side boobs and my cock grew almost immediately in my pajamas!
" I am gonna go lay out today " she tells, " watcha gonna do daddy?,". Told her I was going to just run around and be back later. I immediately walked away try to hide my erection and took a very cold shower!
Later that afternoon, I came home and called out her name but she didn't answer. I started walking towards back yard and through the patio door I saw her laying out face up and topless. I stood staring at her young firm breasts, her pink nipples hard as pebbles, her tiny bumpy areolas
And her tight suit bottom splitting her pussy. I stood and stared for a good 10 minutes, my hands down my pants touching my very stiff erection.
I went in my room, closed the door and started masturbating immediately.
I close my eyes thinking there and was so concentrating on cuming that I didn't notice that I didn't close the door completely and didn't even hear it open.
I opened my eyes for a second and I see her standing in partially open doorway still topless with her hand down her bottom.
I threw the cover over my cock, and tried to say something but the power of speech had left me.
"Were you thinking about me daddy?" She asked.
" Do you like your babygirl?" She added. I still couldn't talk!
" I hear you and mom at night and I did wonder how big you were from moms moaning and now I know why" she continued.i finally recovered and said to her
" Kel I don't think we should be discussing this any further and I am sorry you saw what you saw and let's not say ANYTHING to mom"
She agreed and cupping her breasts seductively she walked back to her room.
I sat in bed for a few minutes until I went soft, threw my shorts back on and jumped in pool to cool off for a few minutes.
I headed back to my room and as I walked by the bathroom, I heard soft moaning coming from there and water splashing. The door was a crack open and I couldn't stop the temptation so I opened it another inch and she was in the bathtub pleasuring herself.i could tell she was almost done because she started rubbing herself harder and harder, her head thrown back, her breasts thrusting out with her nipples hard and finally with a loud groan she had an amazing orgasm and her body went limp.
I walked back into the bedroom, closed my door completely and stroked myself until I came just as hard as she did!
Later that night we had a huge thunderstorm with massive lightning and I am just laying in bed watching TV aimlessly surfing channels but my mind was on Kelsey. As if she was reading my mind, she walks in wearing a see through pink nightie with matching see through underwear showing her bushy pussy.
"Daddy I am scared. Can I lay with you please?" She said shyly. And before I could answer she unfolds blanket and crawls in bed with me and snuggles up to me.
"Kel, I don't think this is such a good idea" I told her. " It's okay daddy. I just feel safe in here" and she snuggled even closer her breasts squeezed against my chest.
I tried not to get hard but her soft warm body wasn't helping.
She slowly slipped her hand over my throbbing cock and started massaging it. "Kel please don't" I said to her. " Daddy it's ok. I want this and I can tell you do too" she said with a giggle with her hand firmly holding my cock.
" Kel, what if mom finds out??" I asked again. " Daddy it WILL be just out secret I promise!"
She then removed the blanket from both of us, took my pajamas off and she took my entire cock in her mouth with one gulp! I almost came immediately. She released my cock from her mouth and said " did I do that right daddy? Never done it before"
And the she removed her panties but left nightie on.
Slowly and deliberately she climbed on top of me and started mounting my cock." Daddy go slow please. I have only been with one boy" she said " and he was not as big as you" she added
Slowly she slid down,moaning like she did in the bathtub.
She was so tight and even as wet as she was, it took a couple of minutes to get all the way inside her.
Finally when I was totally inside her, she started riding me slowly, rocking her hips back and forth. I grabbed her tits and started massaging them, playing with her nipples. That made her rock even better!
She Lowered herself to me, her long hair falling on my face, and I started sucking her nipples harder and harder which brought on more furious rocking, her clit rubbing against me. She the brought her face close to mine and whispered to me " is this what daddy wanted when he was watching me in the tub?"
She then kissed me passionately, her tongue deep inside my mouth, rocking harder and harder, riding me furiously, up and down slowly, kidding me deeper and deeper.
She then released my mouth, started trembling and I knew she was ready to cum.i grabbed her side hips and bounced her up and down on my cock until she screamed with the loudest orgasm I have ever heard.
" Daddy please cum for me, PLEASE"
I didn't need the encouragement as I exploded inside her with a loud groan holding her hips for a long time until every drop was out of me.
She fell on top of me, her now naked breasts against my chest, both of us heaving.
" I love you daddy" she said, kissed me goodnight and rolled over and we cuddled the rest of the night
