"Lets see what we have in here…" she purred making a move for Jo’s top button.Jo was dumb struck. One minute in a job interview, and within thirty...seconds a very attractive brunette had slipped her hands inside her blouse, with four dirty old men looking on.Soon she realised that she’d skilfully unbuttoned her entire blouse. She then pulled Jo to your feet."Wow, they look great…” she whispered in Jo’s ear, her hands gently easing Jo’s tit out into the open.The woman’s lips slowly decended to. As the light shone on his face, Lizzy told her mother.“That guy was in the store.”They looked down and saw that the man had his penis out. It was fully erect and looked huge. He was masturbating openly. Instead of fleeing, Kate held her daughter’s hand and stopped to look at the big cock.“OOO That’s a nice one.” She commented. The man then stepped back into the alley. Kate and Lizzy took a few steps into the alleyway and watched as the man began to jerk off in earnest. As the stranger stroked. I was so nervous that I was trembling. She looked at me and smiled as she squeezed my dick though my jeans. I thought I was dreaming. I couldn’t believe my sister was touching cock. She opened my button and zipper and released my cock. She stared at my hard-on for a minute before taking it in her hand and stroking it. My cock instantly responded to her touch. I felt short of breath and was hyperventilating. I closed my eyes and tried to process what was going on when suddenly I felt her lips. I approached her after class and struck up conversation, asking her for directions.She was even more innocent looking as she spoke, like a little girl she was shy and looked at me sheepishly.We soon became friends, talking more often and hanging out occasionally in our spare time. Although our relationship remained friendly within the first few weeks I knew she caught me looking the times I snuck a peek at her little titties and round ass.One night we had been walking back to my place after.
