The Main Event (missionary vaginal)

As she catches her breath, Ashley's eyes meet yours. "You know," she says quietly, "I've been wanting this for a long time."

"Oh?" you ask.

"All the nights you and Emma thought you were being quiet in her room next door... you weren't that quiet. I think I came harder than you two did," she confesses, her cheeks flushing a deeper shade of red.

You're taken aback for a moment, imagining a teenage Ashley getting off on listening to her sister get fucked.

"And now?" You ask, reaching out to cup her breast in your hand. The way she responds to your touch tells you everything you need to know.

"Now..." She sighs, leaning into your hand as you gently massage her nipple. "Now, Emma can go fuck herself. Because you're gonna fuck me."

She grabs your cock with one hand and with the other pulls your hips into her. She gasps at the contact, feeling you slowly fill her to the hilt. She's impossibly tight, her pussy gripping your cock like it hasn't been in years.

You start thrusting, slow and deliberate. Her moans fill the room as her body responds to your every movement, and she digs her fingernails into your back, urging you on.

As you fuck your wife's little sister in her bed, any guilt you feel is outweighed tenfold, by this forbidden pleasure.

The wet slapping of skin on skin fills the room Ashley's tits bounce with each thrust. She wraps her legs around your waist, pulling you deeper inside her pussy.

"You're so fucking tight," you groan, struggling to maintain control as you thrust harder and faster.

You look down at her face, her eyes closed in ecstasy as she takes every inch of your cock. You thought she was the shy innocent little sister, yet here she is, naked beneath you, fucking her sister's husband.

"Give me that big dick Chuck! Fuck me hard!" she screams. Her pussy grips your dick in a vice-like grip, sending waves of pleasure coursing through your entire body.

"I'm close," you warn her between gritted teeth, sweat dripping from your forehead as you continue to thrust into her tight pussy.

"Cum for me, Chuck" she whimpers, her pussy pulsating around your dick like a vice. The intensity of it all pushes you over the edge, and you can't hold back any longer.

Your hips piston faster, harder, as you feel yourself on the brink of explosion.

"Fuck! Fuck! Fuck!" You moan, thrusting into her one final time as you explode deep inside her pussy. Each pulse of your cock sends another stream of jizz jetting from your dick, filling Emma's little sister up with your cum.

As you collapse on top of her, catching your breath, the gravity of what just happened settles in.
