Holding the handles on the train.Something touched my backside. Maybe it was nothing. After sometimes I felt something again on my butt. This time I c...uld feel a hand grazing across my butt. I tried to turn around. But it was too crowded and one of my leg was stuck in the crowd. I turned my head partially , to see if i can see someone through the corner of my eyes. But I couldn't see anyone standing behind me. While I was trying to do this, the hand started becoming more adventurous. It moved. As I approached them she introduced me “This is an old friend of mine, Liz” I looked at her she looked around 65ish 5’5” quite over weight, silver hair, she was wearing a red and black dress that came to just above her knee.As we talked Nancy had to go to an appointment and I was left talking to Liz. Her husband had died 15 years ago but she was glad cos he was a right bastard, ever since she’s been on her own. She has a good social life so she isn’t bored or anything. After around 20 minutes. At one point I tugged on her nipple and she pulled back. Thinking I was hurting her, I let go. Lynn mumbled “NO!” around mycock, as she pushed her boob into my hand. This time I grasped hernipple a little harder and pulled gently on it. Again, she pulledback, this time I held on and Lynn’s sucking became moreimpassioned.My cock was telling the world that I was on the verge of a bigclimax. Lynn’s tongue tickling the underside of my cock sent meover the edge. My balls felt. I tried to regain some composure but in the water without any clothes on, it isn’t easy to have a nonchalant conversation with another guy, especially when he is totally naked and has you in a Fireman’s Grip while your erection is pressed against his stomach!“You ARE gay then, I take it!” he half-asked, with his grin widening. I just nodded.“Good!” he said. Then he kissed me; full on the mouth and I melted against him as his warm tongue thrust into my mouth and explored feverishly. Our tongues.
