I always enjoyed my life growing up, my Dad had remarried after my Mom ran off with another guy when I was a kid and I got a very hot stepsister to go with an insanely hot stepmom. I remember any time we had a pool party I'd have all my friends coming just to see her in a bikini then when my stepsister turned 18 I'd be the kid guys would befriend just for a chance to get close to her. What I couldn't tell them was seeing her in a bikini was no big deal for me, she had her looks and attitude about nudity from her Scandinavian decent and most of the time when we didn't have guests she'd be nude or topless and encouraged my stepsister, Dad and I to have the same attitude about nudity.
Stepmom also helped me be more comfortable around her, I was awkward for ages, practically walking round with a boner all the time until, with my Dad's blessing, she sat naked in my room and had me jerk off to her a few times but it helped and I didn't feel like I had to buy shares in a hand cream company. My stepsister, Laura, was a bit more reserved, would sunbathe topless but wasn't as fond of me gazing at her breasts and spent less time naked around the house.
One summer, I attempted to be comfortable enough to join the family on a planned trip to a nudist beach. I always wore really long shorts and didn't own any speedos so I spent a few days sunbathing with just a small towel wrapped round my crotch so my cock wouldn't burn, tucked under my ass so the wind wouldn't blow it away. On the hottest day I made the mistake of falling asleep though, I was wearing pretty high factor sun block but woke to my towel gone and my poor cock a pale shade of pink. I went inside to find Laura sitting with the towel on her shoulder and her and her friend Gina laughing. I didn't care that I was naked, I was in pain and wasn't ready to put shorts on my tender cock.
"What the fuck Laura, I now have sunburn, this oil isn't safe for my cock. Where is the aloe?" I said to her, I was pretty mad.
"Why didn't you just wear speedos or something?" She replied.
"I don't own any and I was fine with the towel, where is it?"
"I'll get it, calm your jets pinkie." She said, laughing.
In my rush to get relief I didn't check the bottle she handed me, just squeezed some onto my hand in the bathroom and coated my cock. The cooling lasted a millisecond, the heat that followed was worse than the sunburn and then the smell hit me, fucking deep heat! I yelled out a pretty long line of obscenities which Laura and her friend found hilarious and made my way to the shower to spray it off my cock. I got out with it still burning and went to find the aloe, stepmom had came out of her room, topless as usual, wondering what the noise was and was talking to Laura.
"Why are you yelling and shouting, these two said they pranked you, why is that reason to shout and swear?" She said.
"Laura took the towel I had covering my crotch then gave me deep heat instead of aloe." I said.
"Its really red, I should have got you different tanning oil. Laura, where is the aloe, this isn't funny." Said stepmom, briefly looking at my cock.
"We uh, used it all, we ran out of lube." Replied Laura, Gina went a little red.
"Well you caused this, you fix it." Said Mom who went back to her nap.
The girls led me to Laura's room, they had me lay down and pointed a fan at me, that didn't help, ice actually hurt more but when Gina put her hand in ice water then touched me, that had a different effect and I couldn't help but get a little hard. Something Laura said had me wondering and actually made my cock stir even more, I decided just to ask.
"So why aloe and not just natural juices for your toys, you guys were playing right?" I said, trying to take my mind off Gina's cold hands.
"Yes we were, aloe stays slick longer." Replied Laura.
"Have you showered since you played?" I asked.
"No, why.. Oh..."
"Maybe just touch yourself in the bathroom, get some juices on your hand and touch me, may be enough to cool me off."
Laura stared at me for a few seconds, realized her mom's wrath was not something she wanted and went into the bathroom. She came out a few minutes later but only a couple of her fingers were slick and the relief I got from her rubbing them on my cock was very quickly over.
"Laura's not one for getting really wet. What if, um, you let him put it in just to get coated." Said Gina
"My own brother Gina? No." Replied Laura.
"He's your step brother, not even blood, I mean look at it, is so red but it's a nice cock. You won't be fucking him, just let him put it in you, get a nice coating of your juices then he'll be okay and your mom won't be mad." Said Gina.
"Fine, but I swear Marcus, you do not tell a fucking soul about this and no thrusting, just put it in and keep it there." Said Laura.
"I'll get him hard." Said Gina.
Being naked in my step-sisters room with her friend Gina stroking my cock while Laura stayed on all fours rubbing herself was about as surreal as I'd ever felt, Gina got me hard then led me to Laura's pussy. I pushed into her slowly, enjoying her warm tightness as I slid all 8 inches deep into her. Feeling my full balls resting against her dripping pussy felt amazing, I tried not to move but Laura started squirming and pushing herself against me, when she moved I pulled back a little then when she pushed back on me again I pushed forward too. Laura let out a moan and moved some more then stopped me.
"Gina, go take a swim." She said, her breath heavier.
Gina grinned and left, when Laura's door closed she looked over her should at me.
"Your cock feels really fucking good, if you can make me cum I'll let you do this again." She said.
I started slow, making sure she could feel every bump and contour on my cock then at her insistence, increased my pace, taking my cock almost all the way out before slamming it back inside her. To my delight, I felt her start to cum, her pussy clenching round my cock as she gasped and moaned as she came. When her moans got louder I couldn't hold back anymore and couldn't stop myself, I pushed deep inside her and shuddered as my cock swelled then sprayed the contents of my balls deep inside my stepsister. Feeling me cum set her off again and she leaned forward on the bed gasping as she came a second time. I stayed inside her until I softened then pulled out of her slowly, enjoying the sight of my cum spilling out of her pink shaven pussy.
"Holy fuck that was good." I said as I rolled onto my back beside her.
"Y... you came in me." Said Laura, catching her breath.
"I couldn't help it, you felt amazing."
Before we could say anything more her door opened and my stepmom walked in, she was about to say something then froze, looking down at the cum dribbling from her daughters pussy.
"Well, I'm guessing you don't need this aloe anymore." She finally said to me.
"I uh, it was Gina's idea." I stammered.
"Clean yourself up young lady, Marcus go shower." She said.
I got up, looking down as I went to my room to shower. My cock didn't sting anymore and I had a grin on my face that promptly vanished when my stepmom came into my room and locked my door behind her. She had a pretty stern look on her face that I hadn't seen before and it worried me.
"Now your stepsister is not on birth control, she was quite happy just playing with girls so I didn't feel the need to put her on it. She's on her way to get the morning after pill and those are not cheap. Did you make her cum?" She said.
"A few times, yes." I replied, trying not to look at her naked breasts.
"Well you're going to fuck me too. You're going to work off the $70 I just sent her away with and I'll decide when you're done. You will not tell your Father and if Laura wants to use you too, that is fine but you better keep enough energy for me. Do you know how to eat pussy?"
"I.. I've never really tried."
"Fine, Laura can teach you, suck my nipples until you're hard."
It took me ages to cum a second time but my stepmom came a few times at my efforts, still catching her breath she kissed me on the cheek when she got up off my bed.
"Next time just use sunscreen but nobody cares about tan lines at the beach. Go wash up then come help me with dinner." She said then left.
The hardest part about keeping both my stepmom and sister satisfied was making up stories to my dad as to why I was so tired all the time. Laura would come to my room daily for my oral education closely followed by stepmom to try out my progress then they'd both have me fuck them until I couldn't get hard anymore. One weekend Dad took me for a ride in the car and we stopped for ice cream. He looked at me then just burst out laughing.
"Oh Son you look worn out, I'm so sorry." He said laughing.
"What, why is that funny?" I said, a little irritated.
Dad looked around to make sure nobody was in earshot.
"That week I was away last month I was actually having surgery, part of it means I can't have sex for two whole months and with your stepmother being fucking gorgeous and reluctant to wear clothes most of the time I had to do something to stop her jumping me. She wanted you fucking Laura, she's worried her friend Gina is going to make her a full blown lesbian so she asked me if she could concoct a plan to let you fuck her. Well, you fell into it yourself and she just went with it. I also gave my blessing for her to fuck you too, I know it sounds weird and twisted but I would rather she stayed happy at home and not have urges somewhere else. Your stepmom has a voracious appetite, I can barely keep up at times but from what she's telling me you're doing good."
"Wait, you knew this whole time? How are you okay with this, you basically arranged me to fuck my own stepmom and stepsister."
"My boy, take a step back and look at both women. Both slim, sexy blondes with great tits, both enjoying you fucking and eating them as much as they want. How, on this green earth are you not just high fiving me and saying thanks. I love Carol to death but I also know how lucky I am." He said grinning.
"I, I just feel like I'm betraying you."
"Didn't feel bad for the past 6 weeks you've been balls deep in her though huh?" He said, playfully punching my arm.
"She told me not to say anything."
"I'm teasing son. Now eat up, I want a good nights sleep and I know you're getting a late visitor tonight. She can't fuck me but still wants 4 hour cuddles if she's remotely horny."
The next morning Dad brought me a high energy protein shake and told me to keep it up, I drank it and went to see Laura who'd be waiting for me to eat then fuck her. I had another shake with my lunch then took care of Carol, brief nap, another shake then Carol again before Dad got home. My Dad gets his all clear in two weeks, I just hope I can last that long so I can drop down to just Laura....
