"I had something delivered to the house today. Has that come yet?" Julia asked, almost regretting it as that was probably a source of turmoil for Liam... He was still lost in thought and gestured toward the countertop. It was some super sexy lingerie she had bought for him and a small butt plug she wanted to see if he would wear. "We should go shower together, love!" Julia purred at him. That pulled him from his thoughts because he looked up at her and smiled wide. He just got up and started. It didn’t take long before my cock was fully erect and I started stroking it trying not to look at my sister. I tried to forget she was in the room but no matter how hard I tried I knew she was there, staring at my tiny penis watching me masturbate. However, two and a half minutes later I started becoming more comfortable and somewhat turned the tables on her by closing my eyes and thinking about her in her short shorts and sports bra. It didn’t take long before I was ejaculating all over. I still had to wait nervously for another 10 minutes before he turned up, i waved him over to my car and he got out of his and into the passenger side (so all going to plan so far) he actually looked nervous and asked if this place was safe, I told him it was as quiet as could be expected and that he just had to keep look out while I did what he wanted, he said " o.k let's get on with it" this made my cock twitch being ordered to service him. He then surprised me and asked if first he could. “That backside … Those tits…“Upstairs,” he repeated, pointing. “I want you again.”I knelt on his bed at his instruction, lifting my rump high, tilting my pelvis so he could feed his erection into me.Mister Jennings went at me from behind, sometimes holding tight to my hips, pulling me onto him so my buttocks slapped off his skin, my flesh rippling. At other times he leaned over me, arching over my back so he could hold my breasts. During those moments he would mutter filth into my ear, jabbing.
