Naked Confession Time In The Shower With My Sister (final)

The Saturday morning after the events from the last story, I woke up to take a shower in our parents' master bathroom. They have a wonderfully spacious and luxurious shower. Handheld shower head and supportive shower bench, and a rain shower head with excellent water pressure.

While in the shower, I was using the bench to support myself as I shaved my legs. My sister appeared in the doorway. She had already watched me shower before so this wasn't new. I smiled at her as her eyes scanned up and down my body with the rain feature having water partially danced off my body as I was spread wide reapplying shave gel to my thighs. She was in skimpy pink panties her bush was peeking out a bit and a worn out white cami top. 

She then stepped into the shower with me, still with her clothes on. She sat before me on the bench where I was on full display and had me relax against the wall as she took over shaving my thighs for me. She opened up her curious questions again about my interactions with our family during the COVID years, this time she asked about our dad. She had been enjoying the dildo replica of our dad's dick since the other night I told her about it. She asked if his dick was ever inside me for real. I told it never was, but there were many times he and I enjoyed masturbating around each other. She then asked if I thought our dad would ever enjoy her body. 

My sister is tall and athletic, she played basketball. She is fit and toned, tan, and still slender build with naturally light brunette hair that she's always kept dyed blonde. She's got likely a C cup pair of tits (I never flat out asked her, just guessed). 

I then reached up and pulled the strings of her cami top, her clothes were fully wet by now, and lowered them off her shoulders. She nodded for me to keep going. She was finally ready to be naked for me. I lowered her top some more, slowly exposing her breasts as she leaned forward, teasing my face. I confessed to her that I had always wondered what she looked like, never having seen her naked before. I then exposed her nipples, revealing her bright pink protruding rounded nipples with tiny areolas around them that were slightly darker pink (yes, they were shaped like pencil erasers). I kissed her nipples and told her how beautiful her breasts were and that our dad would really enjoy them.

She moaned as I kept kissing and licking her nipples. She removed the rest of her wet clothes and stood up to let me have a close look at her pussy, with a thick, brunette bush. I brushed my fingers through it and explored her folds, getting a good look at her pussy. I told her she looked a lot like our mom, very tucked in pussy lips with a hint of inner lips peeking, while mine was very puffy outer lips that hid my inner folds. I told her our dad would be into her body very much.

She then shut the shower water off, which wasn't warm anymore anyway. She knelt forward on the bench over me, guiding my hand back to her pussy and having me feel inside her. She whispered in my ear "then offer me to our dad"

I was a little confused on what she meant, cause we were gonna be gone from house-sitting before our parents returned. She saw my confused look and then flatly said "roleplay it with me". So, we both stood up and I dried her off and pampered her a bit and then we walked to our parents' bed where she had left the dildo replica of dad's dick on the bed. Now, everything clicked. 

I played out a scenario where I offered her to my dad instead of having sex with me. My sister then got on the bed and positioned the dildo under as she slid it inside her. She then invited me to lay next to her and "dad" on the bed. I laid beside her as she rode the dildo (7 inches and thick) and said out loud the things she's been wanting to say to him for years. Her lust for him was obvious, similar to the lust I had for our mom. She even confessed being envious that I had a fully sexual relationship with our mom while she didn't get to have one with our dad, and she wanted one for years.

She had one intense orgasm, and kept going, while stating she kept wanting me to watch. She slowed down in between intense orgasms, but kept the dildo inside her until she had a big final one that exhausted her. She laid beside me, sweaty, breathing heavy, her nipples hard and sticking out from her breasts. 

She then rested the dildo on her chest between her hard nipples  and caught her breath before she got up and lead me back to the shower with her. But, that I will keep to myself.
