Event with sis on a bus
Few months ago, myself m(32) and my sis(29) were returning from a get together. Took a bus as we couldn't find a cab service. The evening rush had packed the bus far beyond what it was meant to hold as it was pouring outside. There was hardly any place to stand.
She stood near the middle of the bus, holding the overhead rail. I stood directly behind her, to protect her from any untoward instances. The rush was crazy and people were just swinging front and back.
At first, we tried to laugh it off. I also said sorry. She just snuffed it. Honestly I have really high libido and I can't control myself when it's about sex.
This was repeatedly happening, which got me hard and it started rubbing against her. I could tell that she can feel it.
She was giving no signals. I was scared a bit but honestly I had no choice too. It was making me uncomfortable as the dick was tilting towards left and rubbing weirdly inside my own pants too.
So, I just .. corrected it's position and brought it to the centre, vertically aligned. Now right onto her ass crack. And at this point she looked back and starred into my eyes. A slight angry look.
My dick kept grinding against her until a few minutes later, someone finally got off and a seat became available beside us. She saw it but didn't even move and said I am fine here.
When the conductor said that we are one station away from reaching, she turned around to face me. And now her tits were rubbed too with the movements. Eyes are locked with my cute little sis. All I have is immense care for her honestly. And maybe that is what is making me so horny for her.
The fact that she is liking it too, and that I am protecting her from everyone made me crazy horny. I gave few hard strokes, on her body. And burst into my pants. All she said was "It's okay"
When we reached she held my hand and took me off the bus. Peak life experience.
