Lisa really has to go

With his cock twitching in his pants, Kurt let out a strangled grunt as he lost the battle to his lust, that luscious ass before him was too good to pass up. With a silent apology to Zack, he lifted his hands and reached for Lisa, but just as his palms were about to make contact with her flawless olive skin, the girl groaned painfully.

"Ah, sorry, I need to pee!" she exclaimed, bolting to the bathroom.

Kurt remained seated in the armchair for a few moments in stunned silence as he heard Lisa going into the bathroom and plopping herself down on the toilet. His hard-on wasn't going away though, and that was what snapped him out of his trance.

She's sitting there, he thought. Naked from the waist down. And she didn't finish paying me.

That notion in mind, Kurt narrowed his eyes and entered the bathroom as well. Lisa's eyes widened in shock at his arrival, making her cover her crotch with her hands.

"Kurt?! What the hell?"

"Your debt wasn't fully paid, Lisa," he told her while fiddling with his trunks. "I just came to collect the rest."

The Latina watched with her mouth agape as the older guy pushed down his trunks and pulled his erect cock before her very eyes. Words failed the girl as he began pumping that hard shaft, it was only the second penis she saw in her life after all. Lisa didn't want to see Kurt's dick on that trip, she only had eyes for Zack's. Why am I feeling funny, then? she asked herself, her eyes glued to Kurt's rapidly moving hand. She caught herself checking his cock out, it came close to being as long as Zack's, from what she remembered, and it seemed to be just as thick, causing a warm feeling to boil between her legs.

Kurt's gaze roved over Lisa's sexy, voluptuous body as he pumped his cock, the notion of having the dark-haired girl watching him only serving to make him even more excited. Finally, he couldn't take it anymore. "Wanna touch it?"

The question made Lisa divert her gaze to his face. "I only agreed to this because of Zack, so I can do it with him," she told him in an unsure voice.

"But this is the cock that's here with you right now," Kurt insisted, his hoarse tone betraying his desperation.
