Definitely!

Stacy is still grinding on your lap with your dick between her butt cheeks. She's getting a bit hot and bothered so she reaches down and starts rubbing her clitoris. Faster and faster she rubs, until she cries "oh, oh... I'm gonna cum!"

Stacy tenses up and squeezes your cock between her buttocks as she cums in your lap. You almost explode as well, but you're not quite there yet.

Stacy slides off your lap and Gwen takes her place, facing you and straddling your cock. She smiles and takes her bra off, revealing two sweet little handfuls of titty flesh. Her pink nipples are long and hard like bullets.

Gwen starts rubbing her naked tits all over you. Then she slides down between your legs and pushes her breasts into your lap. Looking up at you with a cheeky smile, she tries to suck her own nipples but fails.

Finally Gwen looks down and pretends to notice your cock for the first time. "Oooh, what do we have here?" she exclaims.

She squishes her tits together and slides her cleavage (what little there is) up and down your cock. You start thrusting your hips, reaching down to pinch and tug at her nipples as you fuck Gwen's tits.

You find yourself daydreaming again. Is this situation not exciting enough for you or something? Anyway, you imagine that you grab Gwen by the ears and **** her down on your cock, fucking her mouth faster and faster. Gwen makes "gak, gak, gak" sounds as you pound her throat with your massive dick. You explode in her mouth and her eyes widen as sperm shoots out of her nose...

But that doesn't really happen. Back to reality. Gwen has been titty-fucking you for a while now and you missed most of it!

Eventually Gwen says "I think that's quite enough of that for now." She gives your dick a little kiss and then tucks it back in your pants. She gets up on her knees, straddles you and lets you snuggle her tits for a bit.

While you suck and nibble on her hard nipples, you slide your hands down and start squeezing and fondling her butt. You undo the ribbons on her hips, causing her panties to fall away. You slide your hand between her legs from behind and you can feel her wet, hairy little pussy.

Then Gwen says "I hope you enjoyed your present, John."

"It was amazing, but is it over now?" you reply, squirming in frustration.

"Yeah, I think we've all gone a bit further than we planned on, but it was really nice." And she gives you a kiss on the lips.

Suddenly you notice that, unknown to Gwen, Stacy is removing your underwear. While Gwen's eyes are locked on yours, Stacy grabs your dick, gently stroking it and aiming it at Gwen's snatch.

When Gwen finally plonks her ass back down in your lap she gets a big surprise as your cock plunges balls-deep right up her cunt. Her eyes open wide and she gasps "Oh my God! You're right inside me!"

Gwen tries to pull herself off but Stacy grabs her hips and slams her back down again. "Go on, fuck him Gwen, it's his birthday!"

Gwen sits there for a moment, getting used to the feeling of your massive dick up her. Your heart is racing. "Gwen, I've been dreaming of this moment!" you groan.

Gwen whispers "I've been dreaming of it too," then gives you a passionate French kiss and starts humping your dick.
