As I sat, I felt my own erection in my pants and felt the need to readjust it within my pants so I can sit more comfortably. As I stood back up to rea...just, I looked down at Sam who was sitting in my computer chair in his polyester shorts pulled slightly down to above his knees, his long skinny fingers wrapped around his penis and tugging slowly. He had no shirt on. We both sat watching the two stars eat each, him masturbating, me slowly rubbing my penis from on top of my shorts from time to. We were just horny and alone in the house all day and, well she made the first move. Aubrey stays with my family for the summer. A couple of weeks in were tired from the pool and bored with Netflix. I was laying around naked in my bed, feeling horny and rubbing myself under my red blanket. Aubrey came in in her PJs and asked me what I was doing. I got sort of embarrassed, but just told her straight up. "I'm masturbating," and laughed about it.She didn't miss a beat. "Cool if I join you?"I had. Her moans filled my ears.I felt her body tense and looked up. There was Mark with his huge cock in his hand. He was straining and grunting as he looked down at Christie and I. I couldn't wait to feel his cum hit my skin. I slithered up Christie's body as she poised herself under Mark's throbbing cock. I watched as his balls tightened, his grunts grew louder and then his cock exploded. Most of his cum landed on Christie, but some found its way to me and I squealed in delight. Oh how I'd missed. Mum smiled at me and let out a nervous laugh, thanks darling she said as she looked down at her open robe. I mean it mum you look good still. It was then I now realised I was flirting with her, she gave it one of those silly stop it and tap me on the shoulder, I noticed her other hand was resting on my knee as well. We began flirting and I couldn’t help but compliment her, which she was loving, giggling and taking them all in. I then started asking her what she had been up to here already. I.
