After riding for some time, I got tired and was sweating heavily on the AC Bus.He guessed I was tired, so he stopped me but kept me in the same positi...n. He thought, got up and came and sat behind me. He held my back a bit higher. He then thrust his dick into my pussy in the doggy style.He gripped my hair with one hand and my boobs with another. He was thrusting my pussy while increasing his pace after every thrust. I started moaning hard. The guys in the front were enjoying a great fucking. She looked so sexy that it wasn’t long before I could not hide my full erection. I ran to my room and stripped off faster than I had ever before. I lay back on the bed stroking myself.The feeling of jerking off felt great. I had only started jerking off, and had still never actually cum before, I was scared and never knew what it would be like.I closed my eyes, seeing granny’s gorgeous face in front of me, making me jerk off hard. I didn’t hear my door open and granny walk in. I didn’t see her. She knew he could always be counted on for a hard fuck from behind providing she didn’t object to him spanking her sensitive ass cheeks for good measure. In her mind, it was a good trade off because the spanking was high on her fetish things to do list and she would often trade spanks with her girlfriend Sandy when they were hard up for some sexual release.Then, poor Sandy got bent over the garbage cans down in the basement by some undocumented dayworkers on a quiet Saturday morning and she was. She then wiped away all the evidence and asked. “Did you enjoy that?” All he did was nod and grin till he handed her the ‘extra’ arrangement. “Maybe ... maybe next time you could suck me off”, he said as she turn to leave and allowing him to dress. “You know the arrangement”, she smiled. “If you are happy with that I will suck you off”.She was surprised at her own comment, just casually said as though sucking a man off was an everyday occurrence, but as that cock exploded and cum gushed out she.
