You don’t hold back anymore. You both want it, and you don’t care what anybody else thinks is wrong

You kiss her again, then break off the kiss in your rush to pull her top off over her head. Then you begin another intense, feverish kiss as you fumble to unbutton and unzip her shorts, then push them down.

Her hands are sliding up your sides, pushing up your tee shirt. She yanks it off over your head. Once your chest is bared, she presses her face to it, placing soft, wet kisses all over your pecs. She shifts on the bed, to kiss down your belly as she opens your jeans. Her hands move with considerably more confidence and skill on your belt and fly, than your awkward efforts on her bra. By the time you get it unhooked, she’s already pulled your jeans and boxers down your legs and off.

She doesn’t hesitate a moment to take your hard, straining cock deep into her mouth. This is the first time you’ve ever felt anything other than your own hand on your cock. The warmth and wetness is an amazing feeling. Her head moves fast, taking you deep each time she bobs forward. You start to panic that you’re going to cum after just two or three seconds.

You grip either side of her head, and pull her back. “Whoa… hold on… or I’m gonna cum too quick.” You gasp out.

When you pull her mouth off your shaft, her hand replaces it. She twists back and forth as she strokes up and down. “It’s not too quick. I want it now.” She grins at you devilishly. Her fingers smear a mix of her saliva and your precum over the head of your cock. It’s too much for you, and your cock erupts. The first spurt lands on your sheet, but Abbie darts forward to wrap her lips around your cock head, eager for the rest of your load.

A shudder runs through your body as you cum into your sister’s mouth. “Ohhh fuuuuck…” you groan. You run your fingers through her hair as she suckles the head gently, and milks the shaft, coaxing the last dribble of cum from you.

You lay there panting as your sister raises her head from your spent cock. She snuggles against you again. Her hand keeps slowly fondling your softening shaft and balls. “Damn, Stretch,” she purrs, “You taste as good as you smell.”

You feel your cheeks and ears get hot as you blush. “I didn’t want to cum so fast. I wanted… to do more. It just felt too good.” You tell her apologetically.

She smiles a satisfied smile when you tell her how good it was. “Don’t worry, you can cum whenever you feel like it with me. I don’t care. Just means I did my job right.” She chuckles. “Plus, I’ll do whatever it takes to get you hard again so we can keep going.” She waggles her eyebrows at you. “After the first few times, you’ll last longer.” She sounds like she means it, and really doesn’t care. That makes you feel a little better, but after doing the same thing with Cyn last night, you’re still a little worried that you might always be this quick on the draw.

Remembering Cyn and last night puts a question in your mind. “Do you think it’s a little weird that you just set me up with Cyn last night, and we’re doing this now?” You ask Abbie as your fingers trace lightly down her bare back.

She laughs. “I think we’re past the point of asking if anything about what we’re doing is weird.” She kisses your collarbone lightly. “But if you’re asking if I feel weird or jealous about what you did with Cyn last night,” she shakes her head, “I don’t. Cyn and I have fucked the same guy before, even done some threesome stuff.”

You nod at that. “She mentioned something about the threesomes.”

Abbie snorts in mock indignation. “She did, huh? I’d have a talk with her about spilling secrets to my family, but after what she saw me doing last night, I don’t think she’d buy that I’m shy about you knowing what a slut I can be.” She giggled.

Abbie continued, “Anyway, if you wanted to see Cyn again, I’d be cool with that.”

You raise your eyebrow at that, surprised, and a little disappointed that Abbie wouldn’t be jealous of you seeing another girl. “Really? I thought we'd be…”

She shakes her head quickly. “Oh, don’t get the wrong idea. I have no intention of being with any other guy than you. I just think you should be able to fuck around. I’ve done plenty of that already. Maybe it’s out of my system. Maybe I just know I’ll never find any guy I want more than you.”

“I could never find a girl better than you, Abs,” you tell her.

She smiles. “You’re so sweet. But you’re an 18-year-old guy. You’re wired to want more pussy than just one. I really don’t mind. At all. I want to see you happy and satisfied, beanpole.” She strokes the side of your face. “Besides, if you think about things logically, if you are only ever seen hanging around with your sister, it’s gonna raise questions. You need to date other girls to give us cover.”

Abbie is blowing your mind by arguing with you that you should date and fuck other girls. The topic of conversation and her still gently stroking hand have brought your cock back to full stiffness. “Well, when it comes down to it, I technically haven’t had any pussy yet, much less more than one.” you snicker.

Her stroking becomes firmer, faster. “That's something I'm planning to fix right the fuck now,” she growled hungrily. She pushes you onto your back and slips her panties off.

Your sister gets up to straddle you. She guides the tip of your cock to her pussy lips, then settles down on it slowly. Her cunt is wet and tight around your shaft. Her head tilts back and she groans ecstatically as she eases down, taking you all the way in. She holds there a moment, then starts to ride up and down, twisting her hips as she does. “Dammit Dave, you feel so good inside me. It’s like your cock was made for my pussy.”

Her rocking speeds up, driving down onto your shaft over and over and over. If you hadn’t just come minutes ago, you know you would have exploded already, but you manage to relax and enjoy the sensation without going over the edge.

You grip her hips with both hands. Her skin is warm and soft under your fingers. You clench a bit tighter and start to guide her to the tempo that you think feels the best, without pushing you to cum right away. She follows your lead.

Then she grabs one of your hands, pulling it away from her hip, and pressing it to her breast. Her pert, firm tit fills your hand. You can feel her stiff nipple press into your palm. You curl your fingers lightly around her breast, kneading gently. She moans and leans into your touch. “Mmmmmm, harder. I won’t break,” she groans out.

Your hand squeezes her tit tighter, you start to arch your hips up into her as she rocks down onto your cock. She’s panting and gasping now, “Ah… ah… ah… ah… ah…” high-pitched quick grunts pushed from her lungs each time your cock plunges into her pussy. Then she slams down on your crotch and holds there while her cunt walls squeeze hard on your shaft and her juices gush. “Fuuuuuuck…” she growls from the back of her throat. Once her shivering is over, she starts to ride you faster, she goes onto all fours, over you. Her face has a ****, urgent expression. “Harder. please. fuck. me. hard,” she pants looking down into your eyes. You grab her hips again and start thrusting up from the mattress, fast and rough. “Yessssss…” she hisses out. Her pussy convulses on your cock again and lets loose another flood onto your crotch. She lowers her head to kiss you hard.

You can’t hold back any longer, you drive your hips up, burying your cock fully. It throbs and pumps your jism deep into your sister’s cunt. She arches her back and cums again, her pussy spasming and constricting on your shaft as it pulses and jets inside her.

After the tension leaves your bodies Abbie collapses on top of you. You love the feeling of her weight pressing down on your chest. You’re both sweating, flushed, and breathing heavily. She squirms to settle in more comfortably on you. You trace your fingers up and down her back. “Damn!” you breathe out low. She just nods her head against your shoulder in agreement. You both lay there, enjoying the closeness of her body draped over yours. The delicious moment stretches on.

Abbie licks your chest, tasting your sweat. “I wanna make all your fantasies come true, Beanpole. Tell me one of your fantasies.” She nips your skin lightly. “Make it a dirty one.” she adds, in a sexy snarl.
