I was on my back on the bed, my legs splayed out to the side as he pounded his cock into me again and again. I always appreciated his stamina and he w...as definitely going to give me all I could handle. He was pulling at my nipples with his mouth as his pelvis smacked into me, his cock driving up into my pussy, grinding against me, bouncing my ass against the bed. As his efforts brought me to orgasm my head thrashed from side to side. Getting a new idea he pulled out and flipped me over, pulling. He parted her soft and inviting lips moist with her passion, licking, sucking, tonguing, his tongue flicking across her hard little clit, then nipping it teasing it.As Pierre orally pleasured her, Darla thrust her hips forward to meet Pierre's probing tongue. Her body stiffened. Her back arched. She pulled his face into her with her hands as she came, moans and screams of passion escaping from her parched lips. However, Pierre could wait no longer, for as he inhaled the sweet smell of Darla's. I could only hear the low mumble of his voice and I was sure the other voice I could hear was Carl's. A minute or two later, I head footsteps coming up the stairs and stepped back into my room. Carl knocked softly at my open door and poked his head in."Joey, Mr. Jarvis would like to see you," he said and then retreated back downstairs. I was so excited, I had to make myself take a couple of deep breaths to calm down. Without trying to be too obvious, I hurried down the stairs and went directly. With a conventional firearm that uses gunpowder to propel a projectile, some of the sound that is heard is caused by the explosion and gases escaping the barrel, while the projectile surpassing supersonic speeds creates a sound--a sonic boom--of its own. Suppressors do a good job of containing the sound of the explosion and the resulting gases, but they do nothing to stop the sonic boom. To be truly silent, or as quiet as you can be, you need to both use a suppressor and fire subsonic.
