Consensual sex in the missionary position

Grabbing the arch-imago, you carry her into the estate and toss her into the bedroom to relieve your stress. Before you can do anything, she's already gotten undressed, hearts in her eyes as she casts a spell, shifting the estate itself around you. Soon, the stone floor is gone, replaced with soft, fertile soil ready for any plant monster to root itself.

"Oh no Verdi, don't modify my body and use me to vent your lust. You'll break me." She said with an eager voice as you undress yourself. Grabbing your mutant genitals, you gently stroke yourself, allowing blood to fill the shaft and inflate the many spikes and tendrils decorating it, wet slaps resounding through the air as both your mare mounters reach their full size. You know you could release your transformation and ravage the mage in ways no living thing had done before, but you want to bully her for her little stunt.

Getting onto the bed, you pin her arms above her head and kiss her on the lips, your tongue extending into hers as she lets out a surprised squeal, struggling to break free. As your tongue invades her, you note how long it is, extending far beyond any normal human and oozing thick slime. Feeling Citrana's body go slack, you soon realize that your genitals weren't the only monstrous part about you, the Enoch skill allowing you to retain your tongue tendril.

Knowing Citranas' stats, you quickly **** your tendril to secrete every muscle relaxant you have, rendering her into nothing more than soft putty in your arms as the **** took effect. Soon, her struggling stops as you withdraw your tongue, the formerly perverse mage now blushing from embarrassment. She can't even look you in the eye as she speaks.

"Verdi, aren't you gonna turn into a monster and ruin me?" She asks nervously as you grin, your plan already bearing fruit. This perverted mage was fine getting every hole stretched beyond repair and having her body altered by a faceless tentacle monster for months on end. If anything, the lack of a human face was something she preferred. Now, she was paralyzed and **** to endure something she had never tasted before: Vanilla sex with a humanoid partner.

"This is my ****." You state firmly, looking down at your freakish monster cocks, the tendrils studding the horse-like shaft continuing to flail about in excitement while the spikes on your sheath grew rigid. It wasn't completely vanilla sex if you had this monster attached to you, but you also know anything less wouldn't do a single thing for Citranas. Aiming one cock to her pussy and the other to her ass, you push forward while kissing Citranas again, causing her to struggle weakly as you enter her. You feel the familiar snug holes swallow you as your tentacles begin stroking her from the inside, each one instinctively rubbing away at her weak points as you bulge her stomach out from your sheer size. Of course, this isn't what occupies Citranas' mind as she continues to struggle against you, the constant kissing causing her to flail around. You eventually let go, giving her a moment to process everything as you begun thrusting, the fleshy spikes on your cock stimulating her while your tendrils squirm inside of her with glee

"Verdi, please, no need to hold back. You should let everything out." She begs, unused to your long, slow thrusts or such affectionate treatment. Your monster side begs begs to go along with her demands, but your more spiteful human side is busy relishing in her discomfort. While slowly thrusting into her, you opt to do the unspeakable, reaching and wrapping your slender hands around her soft, ivory white hands. She yelps at the touch, tightening like a vice around you as she struggles to break free of your hand holding.

"Verdi, please, not like this." She begs as you continue to slowly **** her with the same process of slow, intimate sex. Hours pass as your slow thrusts bring you no closer to orgasm than when you started, but you know Citranas had suffered no less than 10 orgasms during your session, staining her bed with her juices as her protests become mindless groaning and drooling. By now, she's inarticulately mumbling as you french kiss her yet again, her mind reduced to mush from the constant kissing and stroking. Deciding that you had your fun at the eve of your 8th hour of torturing her, you begin thrusting harder, Citranas' already hyper sensitive body twitching at your increase in pace.

"I'm gonna cum. Take it all." You warn while slamming yourself into her, your knot swelling up as you feel your seed stain her insides. You feel the tentacles studding your cock swell up as well, serving as spare outlets for your sperm to leave. Her stomach swells up faster than before, reaching the size of a first trimester pregnancy in seconds. You soon fire another volley, swelling her up even further into her final trimester while her stomach is packed with your seed. You give her one final kiss before withdrawing, watching as your cum flows straight out of her mouth, your prodigious load overfilling her body.

After another 8 shots, your orgasm comes to an end, Citrinas' body now stretched to hold triplets within her. Her entire body is drenched in your sperm thanks to you overfilling her ass, but she is still fixated on your hands holding hers. By now, the muscle relaxants suppressing her body had worn off, but your knots and the exhaustion of 8 hours of nonstop sex leaves the two of you merely panting in overexertion.

"That was mean, Verdi. I like your true form better." Citranas grumbles after a few minutes as you gently withdraw yourself from her, your knot stretching her out before slipping out with an audible pop. Rushing sperm oozes out of both holes as she slowly deflates, her body slowly returning to its default shape.

"We aren't done yet." You say, grabbing the sperm covered mage in a princess carry, her body dripping with your fluids as she bites her lip.

"What's next?" She asked, genuinely afraid as you carry her to the bathroom and set her aside, filling it with water and making sure it was warm to the touch.

"Now you're getting a massage and cleaned up." You say as she scrambles to her feet, only to slip and fall into you.

"I-I-I'm fine! I don't need it!" She protests as you begin scrubbing her down, taking care to clean every last trace of your seed away before massaging her numb body. She protests the entire time, struggling weakly to escape, but her soreness nd fatigue are too much as she ends up falling asleep mid massage, giving you the finale of your ****. Dressing her up in pajamas, you carry her to bed and lay in the covers with her, pretending to sleep with her.

While you didn't manage to vent away all your lust, you did manage to embarrass the arch-imago for an entire night and leave her as an **** drooling mess. Your mind break add on was NOTHING compared to the effects of standard vanilla sex for this deviant pervert.
