Try a bit!

You raise the mushroom to your mouth and find a small piece of the head to bite down on. A dabble of liquid touches your lips, its consistency of a thin jelly passing over them as it attempts to run down your chin. You sweep your fingers up to catch it before sticking them in your mouth. The liquid squirls in with your saliva, the taste slightly sweet and earthy. You remove it from your lips, setting the rest of it gently on a rock next to you before settling in, waiting for the effects to take shape. Sitting on the forest floor, you stare into the woods surrounding you, breathing in the fresh air and calmness. This is the first time you've sat still since early this morning and the change of pace is welcoming. However, it's now that you feel the aches and pains of the trek and your encounter with the witch. You begin to realize how sore your ass feels from the pounding you took. You lean back and rest on your arm as you reach between your legs to gingerly inspect your hole, feeling a bit of pain… but also something else.

You fingers begin to gently rub your sensitive hole as your opening puckers to the motion.

Your thoughts begin to drift, as your start to fantasize about the witch’s cock pounding your ass. The arousal of your daydream mixed with the rubbing of your hole begins to cause your cock to swell. Before you know it, your fingers are playing with your opening, exploring it with mixed pain and pleasure. One slips in and begins rubbing your prostate, gently applying pressure that sends precum dribbling from your head. You feel the weight of your balls increase and begin to sink lower, a side effect of the mushroom's power of increased virility. Another finger has join in on the fun, as the two rhythmically massage and then retreat from your prostate at an ever increasing rate. You feel yourself ramping up, as sweat begins to form on your body. You lay your back on the forest floor, and for the first time let your hands explore your new and improved cock on their own. You immediately notice your hand working harder to keep a grip with your new girth and the greater motion to stroke your cock from base to head. Your breath becomes shallower as your feel yourself riding the edge. You peer down, taking a good look at your bigger mushroom head just in time to blow your load. It rockets out of you, hitting your face three times before continuing to spray all over your chest. The orgasm lasts three times as long as your typical, with you ending up covered in three times the amount of cum.

You lay your head down, your chest rising and falling deeply as you catch your breath. You smile to yourself, knowing that this batch of mushrooms is going to make you a pretty penny back in the village and maybe, you might just keep a portion for your own personal stash.
