Scott drove me home and he was rambling on about how hot that was and how horny it had made him and he stopped the car behind the convenient store two...blocks away from my house. He took out his cock and pulled me down to it and said one word, “Open,” and next thing I knew I was sucking his cock. I didn’t really even want to do this and I hurried and worked him as hard and fast as I could. He was so hot and horny that it didn’t take very long before he exploded. Just as he was starting to. " I teased back. I had forgotten about the food on the table as I felt a familiar feeling of blood rushing down to my cock. A tent forming in my pants. "It's up to you then. Did you want a stranger to help you with your problem, or your mother?" She said with a gesture to the bulge in my pants.I gulped as I thought about it. I mean we had already definitely crossed boundaries last night. After all I had cum inside of my own mother, but we never acknowledged our relationship. Now she was asking. In Kate's wardrobe. At the back of the top shelf were two shoe boxes filled with, what looked like holiday photographs, at the time my only thought, were was that blasted receipt.The following day, feeling bored and lonely, I remembered the pictures and decided to get them out and have some happy thoughts of holidays past. I pulled both boxes out and sat down on the bed to have a look. The top picture was of Kate on a beach somewhere, topless and smiling at the camera. I didn't recognise the. I could feel the eyes on me and knowing that in only a few minutes I was going to be covered in cum was enough to push me over the edge. Chelsea's tongue felt so good as she let it dance across my clit. I felt my body tense as my climax washed over me. She pressed her tongue firmly against my swollen clit as my hips slowly stopped grinding against her face.As my climax subsided I opened my eyes to see Mark above me stroking his throbbing cock. Chelsea moved to lie next to me, our legs entwined.
