'Whatchya doin in here b*o?" Amber?! What the shit!" I'm stunned for a moment as my sister comes barging into my room mid-stroke while I freeze with m... raging hard cock still in hand and pulsing with pleasure. I come to my senses and realize that from this angle she can clearly see me standing erect and firm so I swivel my chair to try and turn my back to her at the same time tucking my cock away. "I know this is your house but you gotta knock first girl." Oh please, not like I don't already. She just wanted to crawl into bed. It had been a long day and this night was getting too long. She yawned."I'm so sorry about all this. I see you're very tired." he said."Yes, it's been a long day. I hope they get here soon." she answered him."Do you mind if I use your bathroom?" he asked."No, I guess not. Follow me." she said as she led him down the small hallway. She went to the right to switch on the light in the bathroom when he grabbed her from behind."Don't scream! I'm not gonna hurt. So I took it out, lowered my suit and started stroking it and playing with my balls.Here eyes were glued to my shaft when she took her hand to her slit, opened her legs a little and started stroking, very slowly, while playing with her nipples over her negligee. Within a minute she came, just like that."Holly shit, what happened here", she said, "I never came this fast. This is too hot."I kept on going slowly and asked her to keep playing with herself but instead she slides over to me and looks. .It is understood that my role is to assist her as she gets the satisfaction she needs from her large sex toys. While she gets completely undressed, my boxer briefs remain on…I lay beside her, my arm wrapped around her, holding her tight, my other hand caressing her tits or pulling her leg back, spreading them open, and holding them up in the air…My entire focus is on her pleasure… She fucks herself with long strokes, pulling her dildo all the way out before sliding its length deep inside….she.
