A lap dance

You eye Brenda's naked body hungrily. She has a much better body than you'd given her credit for over the years and now it's there in all it's glory for you to admire. Her hips are still swaying to the music, her hands running over her own body, as you mentally instructed her to do. But now it's time to raise the heat.

Your legs are parted, your bulge obvious and you tell her with your mind to look at your swollen bulge. And not just to look at it, but to get more aroused the longer she looks at it. You tell her that she wants it, even craves it. But as much as you want to get naked with her, you want it to build up, not to rush it. Since you got her into your room with the premise of her doing a strip tease, it's time to take her to the next level.

"If you're going to try to be a stripper, you have to learn to lap dance," you tell her with a grin.

Your sister smiles, running her tongue along her full lips as she starts to slowly approach you. Brenda's eyes are fastened to your bulge. Her hands are cupped over her own breasts and you see her fingers squeezing the lush mounds. She stops to stand right in front of you. You smile and bring your thighs together.

She releases her breasts and reaches her hands to your shoulders. Your gaze drops to her trimmed mound as she spreads her shapely thighs to straddle your legs. You see the labia of her vagina spread as she parts her legs, then squats to sit on your lap, just above your knees.

You can hear her heavy breathing as your eyes travel up her figure to her full breasts, watching them rise and fall on her chest with her breathing. Her nipples are thick and swollen.

You place your hands on her knees and slide them along her soft, smooth thighs, then to her firm rear end. You cup your sister's cheeks and slide her forward, higher up into your lap. You don't stop until her mound makes contact with your straining crotch.

Brenda breathes in sharply at the contact. You look at her lovely face, seeing her eyes closed. You mentally instruct her to press harder against you and to slowly grind her hips. She emits a soft moan and you see her bite her bottom lip as her hips start to undulate.

Your hands spread her firm cheeks, pulling her tighter until your can feel the heat of her vagina right through your jeans. Your sister's breathing becomes even heavier as she rubs her mound against you.

You slide your hands up along her sides until your touch her heaving breasts, then move your hands over them. Brenda moans as you caress her full breasts, cupping them in your hands and kneading them. She arches her back, her stiff nipples poking into your palms. Her breath catches as you bring your fingers to bear on them, rolling the swollen points, lightly pinching and pulling on them.

Your sister presses her mound harder against your crotch, her fingers digging into your shoulders as she rocks against you. Your hand slip under her breasts, pushing the fleshy orbs higher until her thick teats are pointing right at your mouth.

Brenda gasps, a shudder going through her naked body as your tongue slides out to lick at each swollen nipple. Your tongue tip moves in a circle, tracing her wide aureolas, then fluttering at the sensitive tips. Your lips encircle them in turn, sucking lightly.

Her breathing is more laboured as you suckle her breasts more firmly. She slips a hand to the back of your head, holding your mouth to her swollen breasts as you suck on them. Your sister's back arches to push her fleshy mounds against your lips, urging them wider to get more into your mouth. At the same time, her hips are undulating faster, showing more urgency in her state of arousal.

You slide your hands back down to cup her firm cheeks and pull her harder against your crotch. Your sister moans as you start to grind back against her. Brenda starts to pant, her breathing coming in faster, shorter gasps. You raise your head and pull her against you, arching yourself to press your swollen member harder against her hungry mound.

Brenda rests her head on your shoulders, her arms tightening around you as she grinds harder and faster against you. You feel little quivers going through her and you know what's soon going to happen. You push hard against her, pressing the entire length of your jean covered shaft against her mound, the material and the flap of your zipper bringing more friction to the grinding.

Your sister's body goes stiff for a moment, her arms squeezing you tightly and she presses her open mouth against your shoulder. Brenda let's out a deep moan as her body starts to quiver. Your hands spread her firm ass cheeks to hold her on place as you shift your hips a bit to grind hard against her flooding mound.

She let's out little squeals as her body jerks and spasms in orgasm on your lap. You hold onto her soft body for a while until you feel them start to subside. She lifts her head from your shoulders and looks at you, a dreamy look in her eyes. You tell her with your mind not to care if you're her brother, just to fulfil her needs.

"I want you to fuck me John," she says breathlessly. "I don't care if you're my brother, I just want your cock inside me. Fuck me John. Fuck me now."

Your sister Brenda slides back a bit as she utters those words, a hand dropping down onto your bulge, rubbing it to show her need.
