We have stopped at Macarthur station, grey sky outside and the doors standing open, waiting for the Concord-bound train to come by for the transfers; the wind is whipping by, lashing sheets of rain across the platform. You come up the escalator into a flurry of cold water, a gust right in your face that blows your short coat open and spatters your shirt with cold drops, then once again before you manage to get in the door right in front of me. The front of your shirt is soaked through, clinging and nearly transparent--I can see the flesh of your belly and the curves of your breasts through eh thin material; one fat drop landed directly over your nipple, making it both hard and visible at the same time, and I look you up and down over my book, not shying away from staring at the shape of your body. You catch me looking, but I don't look away, and as the train doors close, you hold my eyes, and when the train starts moving, you breathe deep and turn sideways so I can see the outline of your nipple against the wet fabric.
We climb the slight rise and then drop into the tunnel leading to the Ashby station; the whole way, I am staring at you, smiling a little, imagining you naked, or soaked head to toe, or maybe just on your knees--you can't tell anything except that I am definitely concentrating on you. At Ashby, the doors open again, and a departing passenger shoves past you, pushing you into me, and I reach out to steady you--at least partly to steady you. but my hand lands just below your shoulder, fingers over your collarbone and the palm of my hand firm against the upper slope of your right breast. You jostle into me, and as you press up against me, I shift my hips so you can feel me brush my semi-hard cock against your side; my hand slips down just a little , the bottom of my palm just touching your nipple, hard, firm. I can feel how firm your breast is, supple under my hand. You step back as the door closes, not as fast as you might, and I draw my hand down and away, my finger trailing down and slipping across the erect bud, and now I can see that the other one is hard too, and you're breathing a little more heavily. The train pulls away, and we both sway with it.
A crowd pours in at the Berkeley station, pressing you against me, and I spread my feet a little wider, straddling your hip and pressing forward; you can feel the hard bar of my cock now, rigid through the fabric of my pants, and this time, as you stand against me, I take your wrist and press your hand down until your fingers are on my erection, and then I flex the muscles in my cock so you feel it throb; when I let go, you leave your hand where it is for an extra second, and then you snatch it away--more than you expected. You were lost for a moment, feeling the hot flesh, imagining it in your hand, in your mouth.
