Abbie’s more experienced. Let her take the lead

You step into the house, not really knowing what to expect. You kick off your shoes, and leave your backpack on the floor by the door. “Abbie? I’m home.” You call out. You hear a muffled sound from upstairs, so you start heading up.

As you get to the top of the stairs, you hear Abbie yawn “Beanpole, that you?”

The door to her room is open, so you walk in and find her on her bed, in a sheer nightie. She’s just sitting up. Her hair is tussled. She smiles wide when she sees you. Her voice is a bit thick and sluggish. “Hey Stretch. Sorry, I fell asleep waiting for you. I was gonna greet you at the door.”

You realize that as wiped out as you are, you got more sleep that she did last night. “It’s OK. This is all the greeting I need.” You reassure her as your eyes devour her barely concealed body. You walk over to her on her bed, bend down and kiss her softly on the lips.

Her hand moves to the back of your head, holding you in the kiss for a long moment. The tip of her tongue slips between your lips and then draws back, teasingly inviting yours to follow. You accept the invitation, exploring her mouth with your tongue.

As you kiss her, you feel her other hand press against the front of your jeans. The warmth and pressure of her palm through the denim makes your already stiff cock strain. Your kissing becomes more passionate, rougher. You thrust your tongue deep into her mouth.

She moans. Her fingers clench in your hair. Her hand slides up and down over your cock. You can feel your need to cum building.

You pull back from the kiss. “Slow down.” You pant out. You grip her wrist and pull her hand away from the bulge in your jeans. “I don’t want to cum in my boxers.”

She grins up at you. “Was I getting you that turned on already, little brother?” she asks in a teasing voice. “Mmmmmm… I love that I can have that effect on you.”

You kiss her again, softly. “You have an incredible effect, but I don’t want things to be over before they start.” You chuckle.

“In that case, you’ve got more self-control than a lot of guys your age. I’ve made a few cream in their jeans.” She smiles. “And it’s not nearly over if you do cum. I bet I’ll get you hard again in no time. We’ve got time for a round two, maybe even three, before mom gets home.”

She leans forward and drags her tongue slowly over your jeans where your cock tents them out. There’s less pressure than her hand provided, but the sight is making you even more aroused. “Fuuuck” you groan out. Your knees tremble.

Abbie giggles and shifts over on the bed. “Get in bed with me before you fall over.” She grabs your shirt and tugs her down next to her on the bed.

You stretch out next to Abbie, as she lays back, facing you. Your hand strokes down her arm, then over her hip. “This is so unbelievable.” You murmur low. “Are we really doing this?”

“Fuck, I hope so.” She moans. “It’s all I’ve been able to think about since yesterday morning.”

“Should I go get a condom from my room, or do you have one?” you ask her.

Abbie shakes her head, “Fuck that! I’m on the pill. I get tested regularly,” she says as she unbuckles your belt and unbuttons your jeans, “and I know you haven’t picked anything up from some high school slut.” She tugs down your fly. “I wanna feel you in me, not latex.” She pushes your jeans and boxers down, and her soft, delicate fingers trace over your cock. It twitches and precum oozes from the tip. She leans into you and breathes in your ear. “I want your cum, little brother.” Her hand wraps around the head of your cock, while the tip of her tongue traces around your earlobe.

You know you are losing control when you hear your sister’s words. The feel of her warm hand around the head of your cock just adds to the pleasure. Your hips give an involuntary jerk, and your cock erupts, pumping warm, slick cum into your sister’s palm. She keeps stroking and swirling her hand around the head, the cum lubricating her motions. She shudders. “Yesss!” she hisses out, as if she had been the one to cum. She holds your cockhead lightly, until the last of your jism dribbles out. Dripping through her fingers down onto her sheet.

You feel your face heat up, as you flush with embarrassment. “I didn’t want to… so fast…” you stammer out. “You’re just… so sexy. It felt too good to stop.”

Abbie grins wide. “I already told you not to worry about that. I loved making you cum.” She kisses you deeply. “And technically, you didn’t cum in your boxers. You came in my hand.” She releases your cock and raises her hand to her lips. She makes a show of licking and suckling your sticky load from her palm and fingers, moaning in pleasure as she does. “Dammit…” she closes her eyes. “You don’t just smell good. You taste fucking amazing.”

You’re still shaking as you lay there, watching her. “Abbie… I want to make you feel good, too.”

Abbie laughs, “God… if you only knew.” She snuggles closer to you. “I felt better making you cum, than I ever felt cumming myself with any other guy. I think…” she explains in a soft, hushed voice. “it’s because I love you so much. I never really loved any guy I fucked before. It just feels so good, knowing I made you happy, that I pleased you. It’s like, the most important thing in the world to me.”

You smile at her and stroke your fingers through her hair. “Well… I love you too, and I want to feel how good it is to please you.” You grin. “Fair’s fair, right?”

Your sister smiles devilishly at you. “If you insist.” She says with an ironic tone. “I suppose I wouldn’t mind.” Then giggles. “If you really want to please me, get naked. I want to see your lanky bod, bro.”

You rush and fumble to pull your tee shirt off and push down your jeans and boxers, while Abbie slides her nightie off over her head and slips out of her panties.

You stare in amazement at your sister’s beautiful body.
