The tents

As it was, they were a bit smarter than your usual soldiers - since they seemed to act, with decent expertise. Namely, they kept the fire going - so they always had light and to namely ward of some of the pheromones. Although that part nobody in that time would know about, including having some sentries set up to keep guard - since they assumed beasts in this forest were responsible for the ****.

Although, the Beast could spot the usual human weakness - laziness, sloppiness and simply short-sighed. As there was one tent, that contained two males in them, with barely any sentry able to see towards that specific location. Whilst the others seemed to maintain guard or hang around the fire roaring in the center of the camp. It simply waited for the right moment to sneak two vines inside of the tent.

The two vines were a bit bigger than usual, mainly to keep them restrained when they decided to strike. The Beast needed to keep them quiet once he fed them the nectar. The vines slowly crawling around their bodies, pressing their arms close to their bodies as well as their legs. The bulbous heads placed on their lips teasingly, waiting for the opportune moment to strike and insert into them.

The Beast was patient but gently squeezed a bit to wake them, the bulbous heads would enter their mouths beginning to thrust slowly keeping their mouths closed, and quiet and held down by the tentacles forcing the two to look one another in the eyes as they were violated by the vines. The tips reaching the back of their throats as that sweet nectar began pouring into their mouths and down their throats.

The initial attempt was a bit difficult, since they did awaken and almost immediately started thrashing against the vine inside of their mouths - since it was violating them and had been a rather surprising wake-up for them both. The nectar eventually started doing it's job and they eventually calmed down. Allowing the liquid to be poured down their throats, in likely amounts much larger than given to the others.

Once that was done, the two would almost immediately start rutting each other - giving the Beast a perfect opportunity to seed them both with eggs. As the first one to free himself, immediately penetrated the ass of the other - who was still held by the vines. Keeping his own moan, silenced - otherwise they might be found having fun with the creatures of this forest.
