Samantha offers to help me out

"Hey John," Samantha says. "If it's alright... would it make it easier for you if I helped you... deal with it?"

My eyes widen at her words. "W-what do you mean?" I ask carefully.

"I mean," Samantha struggles to find the right words. "Like... well... your boner will go away if you cum, right?"

"Uhh... usually, yeah."

"So I was thinking I could help make you cum. Y'know, deal with it. With my hand."

I can see Samantha blushing as she speaks. I am in absolute awe at what I am hearing her say.

"Are you serious?" I ask in disbelief.

"Yes, but we need to be fast," Samantha said, glaring at me. "I'd rather Becky and Susan not find out. Got it?"

"O-okay," I say, too stunned to add anything else.

Samantha sits upright beside me and after a quick glance around to make sure no one is watching, she wraps her hand around my erect shaft and starts moving up and down.

"Woah," I moan softly as gentle waves of pleasure start to course through me.

"Is it okay?" Samantha asks, watching me carefully as though afraid she would hurt me.

"Yeah, it's fine," I say. I sit upright leaning back on my hands to get a better view of Samantha stroking my cock.

Samantha releases my cock for a moment to spit into her palms, rubbing them together to create lather before resuming her stroking, now with both hands.

"Oh wow," I gasp as Samantha's two-handed grip fully enveloped my cock. I can feel her fingers running along the tip of my cock as she stroked me, and the feeling was exquisite. Her saliva works well as a makeshift lubricant and her hands slide up and down with ease.

"Where did you learn to do that??" I ask, thoroughly impressed.

"I used to give handjobs to my ex-boyfriend," Samantha says, a small smile on her face. "He was a horny son-of-a-bitch, so I had to give him a lot of these to keep him happy."

"You mean Derrick?"

"Yeah, that asshole. He said that we just weren't connecting, but I know that he left me so that he could fuck Bernice, the slut." I can hear the contempt in Samantha's voice.

"Well, Derrick's an idiot, because your hands feel reeeeally good, Sam," I say.

Samantha chuckles, shaking her head at my comment. "Alright John, no need to butter me up. This is a one-time thing, okay? Don't get used to it."
