Free incest stories: My Sisters’ Tits – Part 2
While my sisters looked almost identical, their personalities were almost opposite. Although they could be highly competitive, Jenny would inevitably take the lead the lead and the more demure Emily would always follow. But, while I knew Jenny preferred girls over boys, I never could figure out my other sister.
As far as I knew, Emily never dated anyone, boy nor girl. I just assumed that having her twin as a lover was enough to keep her satisfied, so maybe she was a lesbian too. It was a bit of a surprise to learn she actually did have an interest in boys, even if she wanted to keep it secret. Why she wanted that, was another mystery.
Undeterred by her reluctance, Jenny pressed on, forcing her twin to react. “Come on Emmy, I only want to help you. I know you’ve been curious about boys for some time. It’s only natural… for most.”
Emily didn’t answer, but stared at her feet and nodded.
“So, do we have a bet?” jenny asked as she knelt next to me.
“Yes” Emily whispered.
Even before Emily had answered, Jenny had already undone my fly and now she pulled down my pants and underwear. My cock had never gotten this hard this fast. In a fraction of a second it was standing like a flagpole, throbbing and ready for action.
“Get on your knees sis, and open your mouth” Jenny ordered.
As directed by our sister, Emily got on her knees in front of me, her face only inches from my groin. Still a little shy, she closed her eyes and opened her mouth. Her slightly extended tongue was a perfect target for me to aim at.
I grabbed my cock and started stroking it. In less than a minute I felt my sperm rush up my penis and watched it land on Emily’s pink tongue. Jet after jet splashed in her mouth, gathering in a small white puddle just behind her teeth.
Only after she was convinced I had given her all I could, my sister closed her mouth and swallowed. Then she opened her mouth again to show us she drank every drop.
Then, she seemed to realize what she just had done, and Emily was once again her demure self. Embarrassed, she threw herself onto the bed, burying her face beneath the pillows.
“Well? Was it everything you hoped for?” Jenny teased as she pulled away the pillows.
“Can you feel your breasts growing?”
This caused her sister to chuckle sheepishly. I could see the relief on Jenny’s face. Although her twin was still unable to talk, and her cheeks were deeply flushed, she wasn’t freaked out too much.
“Just don’t forget to brush your teeth, if you want to kiss me tonight”
Despite her timid nature, only a few hours later, Emily came to my room again, alone. It was almost bedtime and she needed another dose of sperm before she went to sleep. I didn’t know whether she really was that determined to win the bet, or if she had suddenly developed an uncontrollable craving for cum, but I was happy to oblige.
I pulled my penis out while she got into position. Like before, Emily sat dutifully on her knees, her head tilted back a little, mouth opened wide and her tongue stuck out a little.
Dressed in her nightgown, her breasts were still hidden, but her nipples poked through the thin cloth. It was a shame I couldn’t see them, knowing how gorgeous Jenny’s allegedly identical breasts were. Pushing my luck a little more, I grabbed her gown and lifted it a little. She didn’t protest and even raised her arms so I could take it off completely. Now she was dressed in only her panties, looking indeed every bit as gorgeous as her twin had.
Smiling nervously, she opened her mouth again as I commenced stroking my cock. With her eyes she seemed to beg me to give her everything I had, and despite cumming twice already, I shot within seconds. After I had deposited the last drops on her tongue, she closed her mouth and swallowed slowly, moaning as she did. She gave my cock a quick kiss, got up and left without a word.
Satisfied and tired I watched her panty clad ass sway as she walked out. Maybe, one day… I shook my head to rid myself of these perverted and dangerous thoughts. Not long after, I fell asleep.
The next morning I woke early. My mind immediately wandered back to last night and as I thought of my sister’s beautiful body and how her lips had briefly touched my cock. I quickly became hard as rock.
Before I knew it, my hand had found my erection and had started stroking it. For a minute I paused, not wanting to waste my seed by jacking off instead of feeding it to Emily, but then decided to continue. Maybe, if I got rid of this first load now, I would last a little longer the second time.
I had just finished cleaning up after cumming when my bedroom door opened and Emily sneaked in. I could see she was glad I was awake, and even more glad to see my still swollen penis. Without saying a word, she took off gown again and got into position.
Having my gorgeous sister sitting there topless was enough stimulus to keep my cock hard. My plan to lower the pressure in my balls had worked wonderfully. It took quite a bit longer for me to reach orgasm this time. While I was jacking off, the tip briefly touched her tongue. A little drop of precum oozed onto her pink tongue. She must have felt it too, but she didn’t move. A bigger drop followed the first, leaving a slimy trail on her tongue.
After a lingering moment, Emily moved her head back and broke contact with my cock. She closed her mouth, and savored the taste. Then she opened her mouth again and leaned forward a little. I took this as an invitation and moved forward as well. Once more, the tip of my cock gently grazed her tongue.
My sister did not let her tongue get away from my cock again and even licked the underside in a teasing and barely perceptible way. Though my balls felt like they were about to burst, I really didn’t want to cum yet. Hoping Emily wouldn’t notice, I moved my fingers a little closer to the base of my cock and kept stroking the shaft without touching the sensitive head, hoping this reduced stimulation would help me last even longer.
Although my plan seemed to work, I had not anticipated that, with my hand out of the way, my sister would move closer as well. The tip of my cock was now well past her front teeth and extended into the cavity of her mouth.
While I still pretended to jack off in her mouth, I noticed how Emily’s lips closed ever so slightly, as if she secretly wanted to suck my cock, but was too afraid to do so. My heart froze as I waited for my sister to close her mouth around my cock. Never had I wanted anything more than for her to suck my cock right now.
A bolt of electricity shot up my spine as her soft lips finally made contact with the sensitive tip. She halted for a moment to gather courage and then closed her mouth around my cock, allowing the head to fully slip into her warm, wet mouth. I couldn’t believe it; my very own sister was now sucking my cock!
She wasn’t actually sucking on it, but licked my cock and swirled her tongue around the tip for minutes, much like I imagined she’d do when she ate Jenny’s pussy. It was very different from any blow job I’d had before, but no less enjoyable. Much too soon, and with mixed emotions, I registered the unmistakable signs of an imminent and inescapable orgasm.
“I’m gonna cum” I warned Emily.
My sister just nodded, giving me permission to fill her mouth. She stopped licking the head and now really began to suck while I gently fucked her mouth. She moaned softly, sending wonderful vibrations up my shaft that tickled my balls and sent forth the first wave of cum.
Emily never stopped looking deep in my eyes as I came, filling her mouth with jet after jet. Sucking hard she drew every drop from my balls until I had nothing left to give her. I was seeing stars and feeling lightheaded from cumming this hard. It was one of the best orgasms ever, and it was my sister who had caused it!
Still looking at me, Emily let my wilting cock fall from her lips and swallowed my load. She giggled nervously as she got up and gave me another kiss, on my cheek this time.
“Thanks Tom,” she whispered. “See you tomorrow”
After those already incredible two days, things only got hotter. Over the next weeks, Emily taught herself to suck my cock like a pro. Soon her oral skills surpassed even those of Susie, and one day she surprised me by taking my cock all the way up her throat.
Time flew by in an almost continuous orgasmic haze and before I knew it, another month had gone and it was once again time to measure the outcome of the experiment.
Emily and Jenny both undid their tops and the three of us inspected and compared the four gorgeous breasts. With a bit of disappointment I had to acknowledge the fact that Emily’s perky titties were still exactly as big and beautiful as those of her identical twin. Damn, these weeks had been a dream, and I would have been more than happy to continue this experiment for another few months.
Emily seemed to be equally disappointed, although I didn’t know it was because her breasts hadn’t grown one bit, or because of the $50 she had lost. Personally I hoped it was because she no longer had an excuse to suck my cock.
The only one who was acting cheerfully was Jenny. She had won the bet again and she showed it.
“I knew it, I told you” she laughed with a smug smile. “Sperm doesn’t do shit”
“It does work” Emily persisted.
“Then why are your titties so small?” she asked, pinching Emily’s nipples and pulling them up a little.
“Hey! My tits aren’t small!” Emily said, slapping her sister’s hands away. “They’re just as big as yours! Maybe we simply didn’t try long enough. I’m sure if we continue for another month, we’ll see a difference”
I liked where this was going, and so did my cock. It was already swelling in anticipation.
“Hah, you’d like that, wont you? To suck Tommy’s cock some more?”
“No… It’s… I just know it works!”
Emily was lying again, I could see it. Certainly Jenny could see it.
“No, Emmy, You lost and I won. But…”
“But what?”
There was that mischievous smile again.
“There actually is a guaranteed way to make your tits grow, if you’re that desperate to continue. I’ll give you one last chance to win this bet, but you must be crazy if you want to try it. You see, the only possible way to win is if you let him knock you up”
