...she's going to want some milk.

Tara spits a big sticky ball of saliva onto your cock, and starts stroking faster with two hands. This...this wasn't part of the deal. She pushes you back until you sit down onto the edge of the bathtub, almost tumbling in. As you brace yourself, she takes the opportunity to open wide and make your cock disappear into her mouth.
Fuuuuuuck.
"Did you really think I was going to play fair?" Tara's tone is wicked and deeply erotic and terrifying all at the same time. She double pumps you some more, reaching up to stick her tongue in your mouth. either by reflex, or by some submission to her stronger sexual energy, you return the kiss. Is this really happening? You're going to wake up soon. Yeah. That's it. This is a dream, or a nightmare, you can't decide which...but you're definitely going to wake up any second....
You're not waking up, and now Tara is lining up your cock, eyeing with hunger as she hovers over it. What is she...
You get the answer before you finish the thought, as she goes all the way down your cock in one thrust, gagging as she bottoms out against your pubic hair. You can feel her bottom lip graze your nuts, and the feeling is indescribable.

"Oh......fuuuck. God damn it. You really shouldn't...Jeeeeeezus....you really..." you can't seem to finish your protests, because every time you do, she rears back and bottoms out again, still gagging every time, but less and less with each thrust, training her reflex.
This can't go on, and in fact, it's not going to. After a few more seconds, she pulls off of your dick, with tears leaking from her eyes. She stares at you straight in the eyes, a look of pure lust in hers.
"I'm...I'm gonna..."
Tara just nods. "Cum for me, big boy." Her sultry tone is irresistible. You feel the edge approach. You feel yourself crest against it, and now there's no going back.
"FUUUUUUCK!!!" You cum three solid ropes onto her face and outstretched tongue, and she laughs as it hits her. You feel dizzy. This is so fucked up. But it's about to get worse.
"James...babe?" Jenna's voice sounds from the hallway outside. The door handle jiggles against the lock. "James are you in there?" Before you can even try to speak, Tara, puts a hand against your lips, and shouts.
"It's me in here, Ms. Jenna. Sorry." Her smug smile is both infuriating and strangely arousing at the same time.
"Oh. Okay, honey. When you're done in there, can you get Jared up? I need someone to go to the store with me, and I can't find James anywhere, so I'll have to take him."
"Oh sure thing, Ms. Jenna," Tara never breaks eye contact with you while talking through the door. "I'll send him right to you."
After Jenna's footsteps retreat, Tara leans closer and grabs a handful of your hair, ramming her tongue straight down your throat. You can actually taste your own cum on her tongue.
"Mum's the word, big boy. I'll be seeing you later."
She sways out of the bathroom and closes the door behind her. You sit in the wet bathtub, naked, shivering in post-orgasm angst.
