Stop her

Sam quickly pulls away from the kiss, a little startled. "I... uh.... I'm not sure that's a good idea." He says to her finally.

"Sorry..." Phina says, again tears welling in her eyes. "I just.... well... I saw how excited you got earlier..." Her voice trails off as her hand falls into his lap, lightly brushing across his cock. "And I thought maybe you liked me."

"I do." Sam replies, and instantly regrets it. "I mean, you're a really attractive girl, but_" Sam's gasps as he feels Phina's hand now squeeze his cock through his shorts, her grip tightening and his cock once again beginning to grow.

"I'm glad." Phina says, tightening her grip.

"But... with your family here...." Sam falters, "and your dad wants me to help Lauren make lunch...."

As he talks Phina's hand moves to the button on his shorts, fiddling with it, about to undo it.
