“Hey, are these the jeans you were going to wear tonight?”, I asked my sister as I pulled a pair of jeans from my dresser drawer. My sister and I both do our own laundry but sometimes when our parents decide to help they always get at least one clothing item confused.
“Yes, why do you have them? You didn’t jerk off into them or anything did you?”
“No. I told you after the blowjob my urges were done. I’m a new man.”
“… ok, they’re better not be any weird stains on these. Anywhere. If I find out you did anything with these like touched your dick to them or anything like that, so help me god you’re dead.”
“Trust me, I didn’t.”, I lied yet again to my beautiful step sister. The moment I’d found them I knew it was one last chance to get my rocks off to something of hers as she keeps her door shut at all times now and comes in and out of the bathroom fully clothed.
“Ok. Well, I’m getting ready for my date. I’m gonna go get in the shower, my tits, ass, and everything else will be out. I don’t want yo even thinking about me while I’m in there. And don’t try anything funny either.”
“I won’t, I’m done with that stuff now.”
“Good.”
As she turned to go to the bathroom I watched her ass jiggled in her leggings, they were the trendy kind to make her ass look bigger than it already was.
Once I heard the water of the shower turn on I pulled out my cock and started beating it to the memories of my sister’s incredible blowjob to me. Oh, how the memories don’t do it justice.
“Fuck it, she’s going to rat on me eventually anyway, might as well really get my last ideas out of the way first.”, I said to myself.
I began to think of reasons for me to be in the bathroom with her, none too great. Until I got the idea that I could say I burned my hand on the stove cooking myself some dinner and barge in with my cock out ready to be pleased.
It wasn’t a great idea but I’ve already gotten too far into this anyway.
“OW, SHIT! SHIT! SHIT!”, I yelled as I burst into the bathroom, in my efforts to sound frantic and rushed my actions matched my voice and my hard dick knocked over several items on the countertop in the process causing several louds noises.
“Ahhhh! What the hell are you doing?”, my sister screamed.
“I burned my hand on the stove cooking dinner!”
“How bad?”
“Really bad! I need your help!”
She pulled the shower curtain aside to get a better view at what was happening and as she did so she saw my cock hanging out in the air, hard as a rock.
“Fuck you, I thought you were hurt!”
“Sorry, I just needed a way in here with you. As you can see I’m having those urges again and, well, you’re the only way I can get off anymore.”
“I’m not letting you put your cum anywhere on or in my body anymore! Especially after last time! You came in my mouth after I said no to that, you really screwed the pooch on that one.”
“Actually I really screwed you on that one.”
“That just made your little issue to me that much less of a problem for me to deal with.”
“I’m sorry, just let me jerk off to you again. I swear it’ll work this time. You won’t have to blow me or anything.”
“Shut up! I’m not helping you anymore! Just find some porno online and jerk off to that! Their tits are nicer than mine anyway.”
“That’s bullshit! Just let me blow it to you one more time. Please?”
“Oh my god. No! No. Your not putting that nasty dick anywhere near me again. You crossed a line that was not to be crossed and it ruined any chance you ever had of me helping you ever again.”
“So don’t set line, just let me have free reign and then no more boundaries will be crossed! There, problem solved.”
“You’re such a pervert!”
“Please, I’m so hard it’s starting to hurt. I’m dying to nut to you again.”
“50 dollars.”
“What?”
“50 dollars and I’ll let you jerk off to me right here right now. Wet tithes and all.”
“For 50 bucks I better get a reach around too!”
“55 and it’s a deal.”
“Ok.”, I nearly yelled. I was going to get a handy from my sister in the shower! Her nice, wet, massive tits would be fully exposed to me as well as her pussy. I’d never seen it before and was dying to know what it looked, tasted, and felt like.
“Well hurry the fuck up.”
I quickly undressed myself and got into the shower. Her massive breasts swayed and glistened under the water, I never thought they’d be more beautiful than they were on their own. My cock swayed from side to side as I stepped into the shower with my sister.
She reached out and began tugging my dick. It felt great, not as good as her throat or tits but still great nonetheless. I started to twitch already and knew I was only minutes away from spurting my load all over her stomach.
As I was started to go with the motion of her and pump back and forth in her and she released her grip and spat onto her hands and rearranging her grip on my dick to really speed things up. It was working, I began to twitch and expand in her hands as her slobby hands worked their way up and down my cock. After a few speedy pumps and some twisting of her hands I exploded all over her.
My cumshot lasted for nearly 10 seconds and covered her tits to her naval. It was amazing and a sight to behold! I don’t know that she was quite expecting it so quickly because she flinched out of shock and lost her balance, falling to her knees in front me. My cock was once again at eye level with her. She saw the look in my eye, getting ready to ask if she could blow me again.
“No, I’m no-”
As she opened her mouth to enunciate the O in not I “tripped” forward and “accidentally” shoved my cock in her mouth. The previous orsgam’s waves were still washing over me and her wet, warm mouth gave my dick a calling for a few extra shots of cum. Between the unexpected visitor in her throat and the cum pouring down it she began gagging and choking on my cock, causing even more waves of good feelings as her throat spasmed around my head. I pulled out and gave myself a few tugs and shot even more ropes of sticky, warm cum all over her breasts as she regained a normal breathing pattern.
“I’ll let you keep getting off to me, but it’s gonna cost you. And no more dirty tricks like that and the other night. What I say goes and if you abandon that line of command then this is all over and mom and dad are finding out.”
“Sounds like a plan to me.”
