You realize that you really want the feel of a real cock inside you. “Sure Sarah, let’s do it”. Sarah’s eyes light up with glee as she tosses the dildo to the side and attempts to swiftly undress, you laugh as she tries to take off her shirt, getting tangled up in her excitement. You calm her down before helping her, you want her to feel special for her first time, even if it’s just with her older brother.
As she removes her bra you undo her pants. Hooking your hands around her panties you pull both articles of clothing down together, Sarah’s rock hard cock swings up as it is freed, you smoothly dodge it on the upswing, only for it to come back down and smack you anyways. Sarah lets out a giggle and you glare at her, which simply causes her to giggle more, the glare being less than intimidating with her cock resting on your face.
You move back and take a moment to stare at it, her cock is large, far larger than your own, you would feel emasculated that such a little girl was so much more endowed if you weren’t so entranced by it. You grab onto it with both hands, eliciting a groan from Sarah as you do, it feels impossibly hard, heat radiating off of it. Despite all this it looks cute, you don’t know how to describe it. Without thinking you give the head a chaste kiss, Sarah lets out a yelp when you do. “Come on Doug! Stop teasing me” She complains, as she says this you feel her cock pulse in your hands.
Ashley went in dry just fine, but given the option you want Sarah lubed up before she enters your ass. You feel a sense of finality as you open your lips, allowing Sarah’s cock head to slip inside your warm mouth, “it’s too late to turn back at this point” you think. The tip of her cock resting on your tongue, you can’t help but think that it tastes incredible, you give it a lick and taste a bit of her pre, you understand why your mother’s trashy love novels liken the taste to nectar now.
“Oh Doug!” Sarah exclaims, the feeling of a boys warm lips around her cock a new and pleasant experience, instinctively her hands reach for your head, but she stops herself from forcing you to take her deeper, she too wants you to enjoy this as much as possible.
You hum a thank you to her, an act that does not go unappreciated as another spurt of pre leaks from her cock. Sating your curiosity, you begin to take her deeper, her cock touches the back of your throat, and with a deep breath in you push forward. You and Sarah groan at the same time, her from pure please, you from a mixture of pleasure and the uncomfortable feeling of your first deepthroat, your eyes water but you keep going, inch by inch disappearing into your throat. You stop with only a few inches left, unable to move any further for a moment. Sarah has her eyes closed, mind clouded by the incredible new experiences today has offered her.
You pull back slowly, drawing another moan from Sarah, you catch your breath, taking another moment to enjoy the taste of her pre before swallowing her cock again, as you reach the point you stopped last time (Marked by the shine of your saliva) you grab onto Sarah’s hips and pull her forward. She stumbles with a gasp before grabbing your head to stabilize herself, understanding your intent she pulls your head towards her, ramming the last few inches down your throat. Your nose presses against her crotch, the peach fuzz tickling your nose while the oddly masculine musk drives your senses wild. Sarah’s breathing is heavy and lust filled as you hold that position, eventually your lungs demand oxygen once again and you pull off of her.
Sarah lies down on the bed as she tries to catch her breath, automatically you kneel at the bottom of the bed and start to lick her cock, your original goal forgotten, your sole focus on getting your little sister to cum on your, to let you taste her seed.
Luckily Sarah isn’t yet as lost to pleasure as you are, and she stops you, pulling you in for a kiss before standing up. “You’re going to want to brace yourself for this Doug” she says, her voice strained but her breathing even.
You recall the reason you’re here and blush, embarrassed that you lost yourself to the pleasure of sucking your sister’s cock so easily. You stand up and bend over, grabbing onto Sarah’s bed for support. You look back and see her standing there, entranced, the veins on her cock now noticeable. Sarah reaches down and sticks her index and middle fingers into your ass, you moan as they slide in, after several pumps Sarah nods, you’re ready.
You feel empty as she pulls her fingers out, but that feeling is immediately replaced by her large cock pressing against your backdoor. Reflexively you clench down, and Sarah’s initial thrust pushes you forward instead of pushing into you. “Relax Doug” She says in a soothing voice, “I’m not going to hurt you”.
You blush as you let your muscles relax, and yelp as you feel her cock slip inside you, it’s a tight fit, but the pain that you associated with Ashley was gone, all you could feel was a pleasant pressure and a warmth radiating off her cock and into you.
You moaned as Sarah pushed deeper into you, stopping when she reached haflway in. You looked back at her again, her eyes were closed as she tried to center herself, trying to keep from fucking you until she was spent. She pulled back out slowly, agonizingly so, until just her glans remained inside you. A second later she was pushing back in. This continued for a minute, her cock never going deeper than halfway into your ass. The whole time she fucked you this way you felt the pleasure inside you grow, you moaned as she moved, and whimpered when she stopped, unable to communicate with anything but the most primal of noises.
Eventually she stopped, pulling her cock out of you with a pop. “S-Sarah” you managed, still too addled to make a coherent thought, but fervently wishing she would continue.
“Just a second” she panted, her face flush, “I’m going to try something, I just needed a second.” You felt her re-enter you, faster than before, once again reaching halfway inside. “Hold on, I might not be able to control myself after this”
You don’t have time to respond as she begins to gyrate her hips, her cock rubbing against the rim of your ass hole, the tip of her dick grinding against your walls. You cried out, a spark of pleasure originating from your Prostate, you hadn’t noticed before when she was moving slowly, but now every time her head rubbed against it you felt as if your head would explode. You came, a stream of cum thicker than anything you had produced by yourself shooting out and splattering everywhere.
Sarah increased the tempo of her gyrations, her upwards thrusts actually lifting you slightly off the ground. “This is amazing Doug” she cried, suddenly grabbing your hips and thrusting forward, jamming the rest of her cock into your butt in one go. Now she was fucking you, at first attempting to get full thrusts in, pulling all the way out and slamming back in, hard. But she eventually settled on a steadier pace, pulling out only halfway before smashing her hips against yours. The force of her thrusts made your knees weak, you were glad you were holding onto the bed, as she would have fucked you into the ground otherwise. Her balls also swung forward with contact, smashing against your own, while not necessarily painful, the feeling emasculated you, and strangely this turned you on way more than you felt it should. You could feel your cock hardening again.
Sarah thrust into you for a full five minutes before crying out. She hilted in you one last time as she let out a stream of her girl cum. You screamed as you felt her cock expand inside you, and as the first strands of cum shot from her dick you came again. You fell forward onto the bed, Sarah falling on top of you, causing her dick to reach slightly deeper inside you as it continued to pump gallons of baby batter into your guts.
Sarah wrapped her arms around you and pulled you closer to her as you bit the sheets to keep from crying out further. You stayed like this for a couple minutes before Sarah pulled her softening member out of you with another pop. You felt your asshole seal, keeping Sarah’s cum inside you “At least that still works” you thought. Sarah smiled at you weakly as she pulled you in for another kiss. “Thank you Doug, that was wonderful”.
