Mark reaches down under her black lace panties and teases her clit with his finger. She bites her lower lip and moans loudly. Mark moves his face from her breast to her mouth and passionately kisses her. You look down to see Mark's, now fully recovered, hard cock rubbing against her soaked panties.

You kiss your way down her luxuriously soft smooth skin until you reach her panties. Mark's throbbing cock is reaching underneath them and rubbing her clit. You press your nose and lips against Mark's bulge under her panties. Liv strokes your hair with her hand and lifts her hips up, signaling you to remove her panties, so you do. You see Mark's hard rod rubbing against her wet pussy; his precum mingling with her juices. You kiss Liv's labia and lick your way to her clit. In one motion, you lick both Liv's clit and Mark's glans and take them both in your mouth. They both giggle. "That's it" Mark comments "good boy". Mark wraps his arms around Liv as if he's bracing her while kissing her neck. With her clit caught between your tongue and his cock, you repeatedly lick. Liv closes her eyes as her breathing gets heavy and you can hear Mark whispering to her "cum for us... cum for us" repeatedly. With your lips around them, you furiously flick your tongue against her clit. Mark pinches one nipple and aggressively sucks the other. Liv screams out in ecstasy. She grabs your head with her thighs and crushes you against her wet pussy. "Keep going, slut boy!" She commands as Mark bites her neck and twists her nipples. You suck her clit and lap your tongue across her pussy. "Oh, Go~d!" She cries as she cums, squeezing your head between her thighs. [Fuck, I'll pass out] you think [but why does this feel good?].

Liv winds down and lets go of you. With her forearm over her eyes, she catches her breath. She places her hand on your face and pulls you up to her. "Fuck. You really rocked my world, didn't you?" She says "come closer and give mama a kiss" you lie on top of her with your chest pressed against her breasts and she wraps her arms around you as you share a quick soft cuddle.

Mark turns over and pulls a plastic bottle of lube out of the nightstand next to the bed. He stands up behind you presenting his hard upcruved cock for you to see and squeezes the lube over his glans and you watch as it slowly engulfs his cock. "You ready for me?" Mark asks. You lift your ass in the air and caress your asshole with your finger "this ass is always ready for you"

Mark gets back on the bed behind you and Liv. He grabs his cock at the base and touches his glans to your asshole. You feel a submissive vibe take over your body and your ass pushes back against his member, seemingly, by itself. "I'm coming in" Mark says as he gently pets your lower back "relax for me, babe". His touch puts you at ease and your ass accepts his cock's head. "You're doing great" Liv comments as she caresses your face and admires your satisfied submissive expression. Mark puts both hands on your ass cheeks and pushes his shaft through as well. As his cock moves in, you feel it rub against your prostate and a small squirt of cum is pushed out of you and on to Liv's belly. She feels and, before you can react, kisses you. Mark keeps slowly pushing through. "does it hurt?" Mark asks you. "A little" you reply "but please don't stop". Mark is finally balls deep in your ass. He gives you a moment to soak it all in. [I feel so full] you think. Mark leans in to you and kisses your cheek. "I'm going to start moving now" he says. You nod.

With his hands on the bed on either side of you and Liv, Mark pulls his dick out slowly, but before the head leaves your ass, he slides it back in again...and again....and again. The huge cock gliding it's way across your insides feels like it's giving every nerve in its path a tiny orgasm. Everytime Mark stops moving, your anus contracts around his shaft as if to suck him back in. Mark starts thrusting. The bottom of his cock saws across your prostate and you feel your mind slipping. [Co~ck] is the only thought you have right now. Your body is tingling. Mark picks up the pace even more when, suddenly, you hear a clock alarm go off in the other room. Liv extends her arms out towards Mark. He leans in and she wraps her arms around the both of you and kisses Mark. "Happy birthday, dear" Liv says to him. "It certainly is" Mark replies as he continues kissing her with you sandwiched between them. [It's his birthday too?] You think as you're happy to share anything with mark.
