Tit fucking, duh!

Nucleina unbuttoned the rest of her blazer, unlatched her bra and revealing her ginormous 34GG blue titties, grabbed an aphrodisiac lube she was hiding under Gene's seat (obviously she planned this), and rubbed it into her deep, sexy cleavage and onto Gene's rock hard cock, as well as onto his balls. The lube felt lukewarm, and within moments, Gene could feel otherworldly pleasure sinking into his cock, just as Nucleina slowly began massaging it with her 34GG tits. Her nipples were already hard as well, as Gene saw waves of pleasure beginning to overtake the alien with each thrust up and down his thick shaft.

"Ohhh, fuck yeahhh..." Gene moaned loudly as his biggest sexual fantasy was finally coming true. Almost immediately, he felt the familiar tingling of a rapidly oncoming orgasm. he struggled to keep it in, but this being Gene's first true sexual encounter, he knew he'd be an early cummer.

"Don't worry, Gene..." Nucleina whispered as she stared deep into Gene's eyes. "My lube has a special component of... Pleasurrrrre..." Just hearing her in that seductive voice made him blow his biggest load ever. And again. And again. Nucleina held out her tongue to catch his juices flying out from between her tits at the highest speeds Gene didn't know his virginal body could support. His balls suddenly went into overdrive, as the lube somehow enhanced semen production to support extended orgasmic pleasure. Nucleina didn't stop bobbing her tits either, but going slowly up and down, as she also seemed on the verge of orgasm, thanks to the pleasurable properties of her aphrodisiac lube.

"Legwrap! Legwrap!" Nucleina moaned as she tipped the threshold of orgasm. Still cumming himself, Gene complied as fast as possible, and wrapped his legs around her back just as her whole body began twitching and quivering in pure, sexual pleasure as her eyes rolled back. Their bodies convulsed together in orgasmic utopia, providing enough involuntary movement to continue the pleasurable friction of titfucking for almost an additional minute. Gene was completely creaming Nucleina's tits and cleavage just as much as she was cumming into her own work pants.

When Gene and Nucleina's orgams finally settled down, they saw a huge sticky mess; he had given her one of the biggest, messiest pearl necklace he had ever seen, with a veritable ocean of cum all over her tits and in between them, in addition to ruining Gene's work pants as well. They looked deeply into each other's lust-filled eyes and panted.
