This isn't necessarily groping, but it was a consensual sexual experience initiated with a perfect stranger, and it was hot, so I feel like I should write about it since there are so many people here who believe the only way to grope someone is to meet them online first and women who aren't sure of how to initiate.

I was on the train the other day during rush hour and, as usual, looking out for any potential partners. I generally look for women who are positioned next to a guy in a way that makes it obvious she's hoping he'll touch her (he never does, which is where I come in) or women with a nice body and a big ass, because I love women with big butts and a lot of them love when (attractive) men are bold enough to cop a feel. I didn't see anyone that interested me, so I just stood like a normal person and looked at nothing.

Before the train started moving, the woman behind me bent down to sit her bags on the floor, and when she did this her butt rubbed against me. I was obviously turned on and it felt intentional, but she didn't look like the kind of chick who would do that on purpose so I considered it an accident. Once the train starts moving, I feel her butt bounce against me (my butt, since she was kind of tall) every time it jerks, no matter how slightly, and it makes me so hard that I know the people sitting in front of me could see if they were looking. Eventually I take a slight step back and flex my ass hard to see how she reacts. The next time her ass bounces against me, she leaves it there, sliding her cheeks gently so that one of ours is in each others crack. I can feel her sticking her butt out, pressing it against me completely. Her cheeks are tiny and perky, and they're as soft as a pillow. It feels like we're making out with our butts and it makes me so hard that I can feel my dick drooling in my pants.

The train clears out some and a seat becomes available in front of her and she takes it. Before she sits down, she bends back down to get her bags and, as she stands back up, she essentially wipes her ass with my thigh like it's toilet paper, then sits down and doesn't look up from her phone for the rest of the ride. I get off the train before her.

It's probably the most vanilla experience I've ever had with groping but I still get off to the thought of how horny she must have been to do that on a random man's body.
