I kept rubbing and rubbing, thinking about my sister with her hands on her little twat...“Havin' fun there?” My sister asked me. I stopped my jerk...ng, to the dismay of my penis, and nodded. I realized it had just been a few seconds. “Do you mind if I masturbate too?” She asked. “Do whatever you want.” I told her. She nodded, and rolled my desk chair over to the foot of my bed. Then she propped her feed up on my bed and spread her legs so I full view of her aching pussy. I could see that she was. She told me this was just a meeting with the doc so that he could give me an examination and tell me all about the procedure.But before we could get there my mom pulled into a gas station where she took me into the single use ladies bathroom. Mom brought a bag with her and once inside she told me to take my clothes off. She began taking garments out of the bag and folding them over her arm as I stripped everything off as instructed.She produced some white satin panties with black trim around. But he suddenly pushed on the back of her head until Ana had the huge dick fully buried into her soft wet mouth...and she started sucking as he pushed his full hard erection in and out.After that he pushed her against the seat and started to lick her wet pussy and bite her clit. She had a huge cum as he licked her. Then he pulled her over his lap so she straddled him.Ana reached down and guided the head of his big dick into her steamy pussy. She rode him wildly until she got to another intense. She decided to place a finger at her back opening as well and slowly pushed it in feeling dizzy from the sensation. “Maybe your cock will fit in my ass instead, Ethan?”, she whispered excitedly. She had never had thoughts like this before. Her whole body felt like it was on fire and pulsating. After getting used to a single finger, she inserted both her middle and ring fingers into her ass while keeping her index finger in her pussy. She began panting and whining quietly, spasming and got more.
