Start with a nice tit fuck!

"Okay, how about you both 69 while I focus on Aza here?" David suggested to Samus and Katara as he took a seat, letting his erection stand in plain view with his legs parted slightly.

"Would you like a blowjob, Master?" she winked as Samus laid back with Katara getting atop her. "Or perhaps you'd like me to ride you?"

"Neither. I'd like a tit fuck this time," David replied.

"Oh yeah! Coming right up, Master!" Aza declared, leaning forward and wrapping her boobs around his cock, sliding it up the gap between her mounds until the tip poked out of her cleavage. She then proceeded to start pressing her tits together around his cock, and began moving her torso up and down, gasping. Being a Sex Genie made her breasts quite sensitive, so this felt good already on a physical level. But the real treat was the psychological delight she felt at the knowledge that she was pleasing her Master, smiling up at him. They combined into an amazing experience for the magical sex ****.

David leaned back into the couch, letting out a soft, "Oooh... Yeah, that's good.. keep that up..." Aza giggled, pleased that she was fulfilling her **** drive by giving David a good time. She began manipulating her breasts with her hands, moving one up, then back down as she moved the opposite one up, rinse and repeat, even as she moved her torso up and down on him, her coordination with the multiple motions flawless.

Eventually, she reduced the up and down motion of her torso to smaller strokes, opting to leave his tip poking out of her cleavage at all times. The reason for that became evident as she tilted her head forward, proceeding to start licking his cock head. "Ah!" David gasped, leaning his head back, panting with the additional stimulation. Aza giggled as she drew her tongue along his tip in circles, before taking the head of his cock into her mouth, moving to use her wrists to squeeze and shift her soft chest around his cock so she could finger her own nipples.

David moaned, bucking his hips, before turning his head to glance towards Katara and Samus, smiling as he saw them really go at licking each other's slits. He then returned his attention to Aza, before patting her head.

She hummed in delight around his tip, continuing to work her tits on him for several minutes. "Aza, I'm reaching my breaking point..." David grunted out through gritted teeth as he gripped the cushions, his dick beginning to throb in her cleavage.

This only made her redouble her efforts, and she was soon rewarded by him releasing his climax with a pleasured sigh, and she tasted his pearly white seed as it filled her eager mouth. She truly loved the taste of her Master's semen, and she gulped it down greedily. She waited until his member was spent and softening, then she sat up straight, letting it slip from out of her sacred valley. "...wow, Master... That was truly fun..." she purred.

"Yeah, I loved it too," David breathed, basking in the haze of post orgasmic bliss.
