Keep the secret

Will has the fire going well, it should hold off the cold mist that will roll off the water tonight. Allison and Marcus have been gone for some time! He's glad the place he found is going over well. Allison had been hesitant at first, but he was sure she found a way to have fun. He unpacks the camp food and arranges the chairs around the fire. They should come back soon, the sun is almost setting.

~Allison shakily pulls herself to her feet and looks about ready to fall over. Her poor quim has never felt so used before. Marcus must've given it all he had. He has had girlfriends before, more partners than Will or she by a lot. She turns to look back at him. Spent, he had rolled off of her. He is sitting up now in a shallow puddle, and his member is growing again to full hardness, peeking up out of the water like the Loch Ness monster.
"No, not again." Allison says emphatically. "We have to get back!"
"I'm not doing it on purpose, Alli, Honest!" he fires back.
"Look, I know I'm not helping with my attire or whatever" she indicates her still sagging shorts and soaked shirt "But you have to keep it back, man! Will's gonna have questions if you come back with that cannon pointin' north like that!"
"I said I can't help it" Marcus repeats.
"Well, I don't think I can take THAT again, my knees are wobbling and it feels like you tried to rip my tit off." Allison says, massaging her chest where he had grabbed hold while ramming her.
"Hell, Alli, I don't know how to get rid of it. I kept hoping it would go down in the lake, but it didn't." He stands up out of the pool, and pulls his underwear up.
"What if he comes looking?" Allison worried out loud, looking toward the camp where the smoke from a fire is rising. "We should start heading back and think of something before we get there." Together they start toward the narrow trail to the camp.

~Unfortunately for the two friends, Marcus' 'problem' has not subsided before they get to the camp. Allison takes a moment to asses the situation before they step out of the woods toward the camp clearing. Ok, Marcus, we have a couple of options here, she takes a peek at Will through the trees.
"I can distract him while you make way to the tent and 'take care' of yourself. Or, um, well, we could go over there," She says, blushing a bit, and get far enough away and..."
"And what?" Marcus asks, very distracted by the erection. "You said you couldn't take any more."
"-And I could blow you. But we'd have to be reallly quiet and quick about it!"
