Paint her pussy with it

"Oh fuck David, not inside me! Pull out and shoot it all over my pussy! I want to feel your hot spunk covering my pussy lips" Alyssa pleads body still trembling in orgasm.

Not about to argue that, you begin doubling your efforts, continuing your **** on her helpless body while the intense pressure steadily builds inside your balls. Finally, as you feel the cum boiling up from your loins, you pull out from her, roll her onto her back, and take hold of your cock, squeezing it tight to keep from exploding right then and there. Alyssa grabs hold behind one of her legs, pulling it to her chest and spreading herself wide for you and you quickly slip your cockhead back between her lips. When you release the stranglehold you had on yourself it's like a dam just opened and hot jizz begins pouring out of you. The release is incredible and you can't help but let out another, loud, groan as your legs buckle beneath you from the sensation. Regaining control, you start pumping your shaft, spurting more and more of your cum onto Alyssa's swollen labia as she lets out euphoric cries of glee at the sensation until your balls are finally emptied.

After squeezing the last drop of cum from your cock, you take a step back then flop down onto the couch next to her. Still reeling in her orgasmic bliss, Alyssa releases her leg, letting it fall over and roll her back onto her side, ass pointed at her sister across the room. Very aware of that fact, she grabs hold of her ass cheek and lifts it, giving Danielle a better view of her freshly, creampied cunt.

"Holy shit Danielle, what a fuckin' birthday present! Does my pussy look absolutely abused?" she asks her. "I haven't had a dick that big inside me in years! You've got to feel that thing inside you!"

Alyssa then moves to stand up from the couch, climbing onto her shaky legs and says to both of you. "I'd love to stick around and watch the two of you, but I really should go clean myself up a bit. You two have fun, that is, if you've got anything left in you David" she says to you with a chuckle, then leaves the room, making her way to the bathroom.

You watch Alyssa's ass jiggle and shake as she walks away until she disappears around the corner then turn and smile at Danielle. "I promised you I'd be able to go again after I finished with her." you say, slowly stroking your cock to try and keep it engorged. "Well, what do you say? Do you think you want to take me up on that offer?"
