I’ve always been interested in public play and my partner was well aware of that. She’d never particularly shown much of an interest in it and I never put any pressure on her to make anything happen because It never came up in conversation besides a few times in passing. We were on the train on the way from her place to mine (about a 40min journey). We sat in a carriage with people dotted throughout but it wasn’t too busy. We put some headphones in and sat down on a row of 2 seats facing towards the front of the carriage. The train set off and I started looking out the window at the world passing by until I felt her hand creeping up my leg. It was quite usual for her to rest her hand on my thigh but it started drifting up. I shrugged it off assuming it was an accident but she kept pushing up until she was lightly brushing over my crotch. I could feel myself starting to pulse down there and, not wanting to seem like i was causing any trouble i take her hand and squeeze it. She squeezed my hand back but let go and took off her hoodie, laying it across my lap. I looked over at her with desperate eyes and she smiled at me. She slipped her hand underneath the hoodie and started rubbing me through my trousers. I had to bite my tongue to stop myself from moaning. It took a matter of seconds before I was climaxing and felt that warm fuzzy release. My leg twitched and I remember she kept her hand firmly on me, like she enjoyed feeling my pulse through my damp patch. The rest of the journey we sat in silence, not saying a word to each other. I’m just waiting for a good opportunity to return the favour…
