Kind of, but give her a scare while you do

You decide Abbie’s worked up enough, and it would be fun to play out the scene. It won’t be exactly what she’s expecting, though.

As you instantly move her and yourself through time and space again, you rewrite her memory. She remembers having a fun social life, similar to her real life, with lots of dating, hand stuff and oral, but never actually fucking a guy. She always felt like she was saving herself for the exact right one at the exact right moment.

She doesn’t remember the night a few weeks ago that you showed her the chaos magic website. In her memory, a group of women who were regulars in the coffee shop told her they were a coven and recruited her to join them. They showed her some minor spells and then told her to increase her powers, she would have to perform a ritual to summon the god of magic. They drove her into the mountains several hours from where you live, hiked into the woods to a small clearing, told her to strip, and left her alone.

Now she is in that clearing, naked in the dark.

You walk out of the woods in your original form. Her familiar brother, looking just like you did this morning in her memory.

She yelps in surprise and tries to cover her tits with one arm and her pussy with her other hand. “Fuck! Dave, what are you doing here?” she yells at you.

You stagger as you walk toward her. “Abbie?” you say, sounding confused. “Where are we? What’s going on?”

“Dave, you fuckin’ perv, I swear…” she begins. You sense her mind and know she's both embarrassed and irate at your finding her like this.

You cut her off. “Your brother is merely my vessel,” You say in a deep, gravelly bass voice. “He has served his use.”

“What the fuck?” she blurts out as you start to transform.

There is a sound of cracking bones and ripping cloth as your body grows and stretches, tearing out of your tee shirt and jeans. You grow over 7 feet tall. Your muscles bulge. Your legs become thick-furred goat’s limbs with cloven hooves. You sprout horns from your head and a long, snaking, barbed tail grows from the base of your spine. Your cock is massive now, fully hard, over a foot long, soda can thick, crisscrossed with pulsing veins, and drooling a continuous dribble of precum.

Abbie shrieks at seeing this monstrous form almost erupting from her brother’s body. You take a long stride toward her. She turns and runs into the woods, her heart pounding. You catch her easily after just a few leaping bounds. Your thick, clawed fingers close on the back of her neck. You yank her backward, dropping her on her back to the forest floor on a litter of dried pine needles.

She shakes her head back and forth in a panic, screaming, “No! NO!”

You crouch down, cup one of her big, soft tits in your now huge hand, and squeeze. At the same time, you take control of her body; you make her cum as hard as she ever has in her life. Her juices squirt out onto the needle-covered ground. All her muscles lock up, and her body shudders.

You move between her legs and pull them wide apart. You lower your hulking form down over her soft, curvy body. You grip her wrists and pin them to the ground above her head in the iron grip of one hand. The engorged, dripping head of your cock prods between her thighs. You thrust, driving into her. Stretching her open.

You make her cum again. Her head tosses back against the ground, and her body bucks under you. Her pussy contracts over and over on your huge, rock-hard shaft, and warm fluid floods around your shaft and gushes down to the forest floor.

You start to rut into her. Your violent, punishing thrusts drive her body forward on the dirt and pine needles. Every time you plunge your giant cock into her stretched cunt, her toned belly bulges from the invasion. You keep her cumming over and over throughout the entire experience.

She turns her head and closes her eyes to avoid seeing you. You control her muscles, making her look up into your face and forcing her eyelids wide. You look down into her eyes; yours are lit dull red like burning embers.

When you make eye contact, you let yourself cum. Spurt after spurt of hotter-than-human semen erupts deep in her pussy. Overfilling her cunt, it froths out around your fat, pistoning member.

You pull out of her and stand over her. Your cock is still twitching and dribbling cum down onto her belly. You finally let her stop cumming. She lays in the dirt, sucking in deep, ragged breaths. Her body is too exhausted to move.

You teleport back to your bedroom. As you do, you transform back into your old body, repair any physical harm she suffered, and restore her proper memories.

“You dick!” she shouts and punches your arm hard. After she takes a deep, calming breath, she says, “I’ve never been so terrified in my life. It was fucking hot!”
