It was just a normal dayin school, when I saw my sister joking with her schoolmate about sex stuffs. Healso touched her boobs and grabbed her ass, mak...ing her smile and chuckle. Next day,she wasn't in school, saying that she didn't feel good and all...I came home earlierthat day, came in the house and heard some moaning and laughing. I slowly approachedto my sister's bedroom, slowly opened doors and what I saw was just: "What the hell?!".She was getting fucked in her wet pussy by that schoolmate. .”, and giggled. She started riding him again. But, this time I could tell she was more confident, and really enjoying it. She was running her fingers thru her blond hair with her eyes closed.Bouncing up and down. She sounded so wet,..and opened. I want to fuck her. I want to see her naked. I want to see that ass that is getting fucked. She was swaying. She must of been circling her ass on his cock as she went up and down. “Mmmmm” was all she was saying this round, until her boyfriend really. “Yeah. Can you do that? You don’t have…”“Are you trying to talk me out of it?” she interrupted.No, no. Once again I could hear my known mother on the end of something I don’t want happening. An end to something I’d rather gain instead.“It’s a relatively fair exchange,” she went on. “I’m invested. I can’t have you walking around with that painful boner for such long hours any longer. If this is what needs to be done then I’m on it.”Another pause. I said nothing to what the both of us were. “It’s ruining my hair, this weather,” she complains. Does she think I look like I care? “On your knees, bitch.” “I’ll ladder my stockings!” “Well then walk home in unladdered stockings.” She gives me a look that speaks volumes, then drops to her knees. “Open your mouth!” I push her head back against the unforgiving metal. Rain falling, hard drops, cold. Darkness surrounds us, save for the glow that filters back from the inside and outside lights. The swish of tyres and the hum of engines.
