Zack finds a treasure inside the bathroom

As Zack was about to get into the shower, he spotted something purple underneath the counter. It was a dainty piece of frilly underwear, and it was very familiar. More than once had he seen the pink number hugging Lisa's tight ass back when they were still dating. Zack picked it up, inspecting it out of boyish curiosity and nostalgia. Although he realized he didn't love Lisa in the end, there was nothing to complain about in the sheets. A slim body. Curves where they were needed. And she often went into this pink haze when they were fucking that didn't end until they were both spent and messy.

"Oh, great," Zack groaned when he noticed his cock had become erect from his memories of Lisa. A naughty thought crossed his mind, and behind the locked bathroom door he decided to indulge it. Zack wrapped Lisa's used panties around his shaft and began to pump it. He closed his eyes and summoned the memory of their first night together. Lisa's bashfulness quickly melting into high-pitched moaning within a few thrusts of his cock. He could still remember how her pussy felt wrapped around his bare cock.

Zack was getting into the rhythm when there was a rap on his door.

"Hey, Zack, do you see my underwear in there? I can't seem to find it." Of course, the underwear in question was wrapped around his cock. What shocked Zack was the fact that it wasn't Lisa's voice that asked. It was Hannah. Fuck. The image of Lisa taking his cock transformed into his first crush.

"Ye-yeah. I see it."

"Oh, great. I was looking high and low for it," Hannah said. "Hey, you better not do anything naughty with it, alright?"

"Now that you mentioned it..." Zack joked, **** to hide the anxiety in his voice. Despite this, his hands hadn't stopped stroking his cock.

"Hahah, you ass," she giggled and left. Holy shit, now I've done it.

Since he was already in the deep and couldn't undo his mistake, Zack decided to continue masturbating with Hannah's panties until he came into the slip of cloth. Gooey semen exploded between his fingers and drenched the panties until it was a messy rag. After coming off his post orgasm high, Zack scrubbed it clean and wrung it as dry as possible, before finishing his shower. He hung the panties up by the door and pretended he forgot about it.

He was worried about getting caught when he came out, but both Hannah and Lisa were nowhere in sight. They must have gone to the dining room already. Zack sighed in relief and dressed up.
