Suddenly I heard footsteps on the stairs. My door cracked open and she came in wearing a loose fitting button down shirt and skirt from church. All I ...ould focus on was the outline of her breasts underneath it. She was already unbuttoning herself as she walked towards the bed."All ready for me, I see," She said, smiling. I nodded at her eagerly. She sat on the edge of the bed and bore her breast to me. I quickly laid across her lap, falling into her cradling arms and felt the bulbous softness. I hadn’t fucked a hot pussy since I screwed a drunk, long-haul groupie in Omaha three weeks earlier, so I was primed to cum in just a few minutes. My balls began to pump for joy as they fired shot after shot into my sister's body. When I was finished, she lay back on the bed motionless, breathing deeply, eyes closed, the hint of a smile caressed her closed lips. My cock twitched one final spurt of juice then I let it slip out. I stood beside the bed and looked at the body lying in front of me. Her tongue danced around his cockhead as Sam moved up and down his shaft taking more of him with each stroke. Her hands rubbing up and down his thighs as her head bobbed… gently tweaking his balls with her fingernails at the upper end of her stroke. The sensation of Sam’s beautiful lively mouth and having both thighs massaged was intensely sensual. Sam quickened her stroke as she sensed his need then focused on his velvet glans – sucking hard and working her tongue. Roy felt that rush of warmth. As she sat on him he and her groaned at the same time, as she bounced up and down on his cock he licked her nipples, then she grabbed the other lad and fed him into her mouth. After watching all this from the bathroom I was already naked and feeling my rock hard 6” I needed to get in on the action, I lubed up my cock and walked over to the bed.Kneeling on I teased Donna’s ass with my tool, she groaned, then inched my way in, she groaned real loud as I fucked her ass as the other guy fucked her.
