My sister's workout part 2

... looked at me. "We can get to the park faster.. If you ride with me like you did with Liz yesterday" she brought my bike to me while explaining. "Don't wanna run to the park?" "Noo.. Lets head to park first.. Now hurry up". She said tapping the seat of my bike. "all right, whatever my princess say.." I started to ride with her. She had rode my bike with me couple of times. Its not a new experience for her. "What's up with the hoodie ?" She had covered her face with her jacket hoodie. "Ahh.. You will see..." She was smiling. I didn't give it much of a thought. I stopped near the bench that we rested yesterday. "All right, sit there". She pointed at the bench. " Huh?" "Sit and shut up". She sounded so bossy, like our mom. I sat on the bench looking at my sister Standing in front of me. She quickly kneeled in front of me as soon as my ass hit the bench, like getting ready to give me a blow job. 'Noo way.. it can't be..' Thinking about it, was enough to made me hard. She surprised me by touching my hard cock, rubbing up and down, while looking at my face. Her gentle fingers moving around my cock was driving me mad. "Some one will see Jules.." I said while looking around. There are some people who use this path to run sometimes.

I saw a person running toward us through the woods. " Ohh.. God Jules someone's coming" I heard her giggling, she pulled her hoodie up to cover her face while taking my cock in to her warm mouth. No one can't identify her like that. She was hiding her face in my crotch. But me? Any one can see my face clearly. "Ohh.. God Jules, you are killing me" I groaned with pleasure. She had wrapped her tongue around my cock, while moving her head up and down. I didn't care about who saw or what will happen, i only cared about right now with my sister's tongue and lips on my shaft, trying to blow me best as she know. I looked at the person who was coming running toward us. 'Ohh.. Shit, it's a young girl, around my sister's age'. She stopped from seeing us, her hand move to cover her opened mouth, her face became pale like she saw a ghost. 'May be its her first time seeing a some one sucking a hard cock, I will give her a good show that will never leave her young innocent mind' I was lost in my horny thoughts. I was so close to cum at that time. "I'm gonna cum baby..." I warned my sister. She took her face away from my cock and start pumping faster up and down with one ...
