On her tits and sort of

It was obvious Amy didn't have much experience with this kind of thing but she was making up for it with effort. She jerked her hands on his dick as she drove his dick down her throat, resulting in a sort of gagging punctuating every few strokes.

When he couldn't stand it any longer, he pulled back a little and blasted all over her bathing suit cover-up and bikini top.

"I wanted to swallow that," she said. "They do in all the porn videos."

"Scoop some up, then," Matt said.

She did, then made a face. "Yuck."

"I'm sure you'll get used to it."

"Want me to rub it into my tits?"

Did he want that? "Hell, yes."

Amy stripped off her coverup and then her bikini top and proceeded to massage his cum into her tits and flat belly.

"I won't shower before the dance," she whispered. "That way, when you're dancing with me, you'll know that I've got your cum juices all over me."

Which is when Karen walked into his room.

"What the hell?" his sister shouted.
