I licked her until she started to shake at which time she began riding my face like a mechanical bull. She rubbed her pussy all over it and finally st...rted to slide down my body to my eager cock. When I could feel the tip of my dick right up against her pussy lips, she abruptly rolled off of me and lay next to me with her mouth up against my ear. She took my hand and guided it down to my dick and whispered,"He made me promise him that I wouldn't fuck you when I got home. He wanted to know that. My turn came and I wished it could have been less public. I would have much preferred it to be in my bed chamber alone with Ralph but I knew I couldn’t go back on my word to Auntie. Ralph led me to a chaise longue and slowly removed my dress. Without the uplift of the cups, my breasts looked decidedly small, a fact that did not go unnoticed by my rival. “If it wasn’t for the slit between her legs, she could be mistaken for a boy,” she remarked cattily and loudly enough for the other guests to. Ricky eventually asked if I ever had sex and when I told him yes and as a matter of fact I once blew Mr. Phillips, the science teacher at our school he was really surprised and got a big kick out of that. I asked him if he ever had sex and at first he said yes, then hesitated and said no, that he never has. I told him I couldn’t believe a good looking and sexy guy like him has never had sex! He looked embarrassed by so and I put my hand on his crotch and squeezed his half hard cock thru his. I looked around and no one seemed to be looking, I was near the front of the bus and two seats were facing me but they were empty. I slowly slipped my hands under my skirt to assess the damage, I wondered if I could tie it back together somehow but it was no good. I pulled at the waistband to try and get enough material to fix it together but…snap…oh fuck again!I looked down and my ruined underwear was beyond saving, I couldn't leave it there because it was so noticeable, I teased and pulled.
