Tell her that she needed to hide the evidence

She shuddered at your words, exhausted, aroused and humiliated, but she pulled herself off you and began to look around for a rag or anything else to use and finding nothing (hardly a surprise as you’d removed anything which might be used for that). “How?” she finally asked.

“Come here,” you ordered. She started towards you, cut off by your sudden command to crawl. The buxom redhead dropped to all fours, crawling towards you like a bitch in heat.
“We can’t leave any evidence,” you say.

“How c—“ Brigitte began.

You cut her off by pulling her head to the pool of semen and girl-cum on your belly, placed there by her orgasm and order her to lick it clean and swallow the evidence. The small tongue that had tasted her own juices and sucked cock for the first time with you, swept over your firm stomach, eagerly lapping up every trace of your shared seed. Your still hard cock brushed against the side of her face, leaving the occasional droplet of cum on her cheek, which she hungrily pulled to her mouth.

With your stomach clean, she dropped, without further orders to your cock, cleaning it of every trace that it had ever cum, let alone that it had just filled her formerly virgin ass with an impressive load of jizz. The feel of her silken tongue on your sensitive cock was somewhere between painful and pleasant. Your fingers ran through her long red hair (and used it to dry the saliva from your stomach. When she rose off your, now clean and softening cock, she had a simple question, what about her? She was dripping cum and while the sweat could be explained, leaving trails of cum around might give her away.

“Lie down,” you commanded.

The busty redhead lay back in the dirt, expecting you to return the favor.
