Mom and Dad won't be back for a few days. You know...we could do something about that."
"Well...I...uhh..," I muttered, conflicted greatly in my feelings.
----------
My sister Dina always liked to show her body off, but with my previous wish it enhanced her abilaty to not care about embarrssing herself; she once wore a thong and a bra, and didn't care too much, except she never walked around nude since our parents would notice and that would be hard to explain.
But to see my sister like this, and to be offered the chance which we could not do ever!
I decided to accept my sisters offer and I followed my sister to her room. When inside Dina helped me out of my clothes and she then took one step back away from me towards the bed.
Dina then started to fondle herself and then look at me and give me a horny sorter smile.
