Bathroom Sex - Thursday, March 12, Morning
I woke up already wet, my new cock half-hard against my mound and my pussy throbbing with that familiar ache. David’s arm was draped over me, his thick cock pressed against my ass. I slipped out of bed and hurried to the bathroom, my bladder screaming. The moment I sat down, David followed, his heavy shaft already stiff in his fist.
“Open,” he said, stepping close. I took him between my lips just as the stream started. The sound of my piss hitting the bowl mixed with the wet noises of my mouth sliding up and down his cock. He groaned, fingers in my hair, feeding me more while I emptied myself. When the last trickle stopped, he pulled me up, spun me around, and bent me over the counter.
His cock drove straight into my dripping pussy in one thrust. “Fuck, Mary,” he growled, hips snapping. “You’re soaked already.” I braced against the sink, watching us in the mirror as he pounded me, his balls slapping my thighs. My own shaft bobbed beneath me, dripping onto the floor. He reached around and stroked it in time with his thrusts until I came hard, clenching around him and spraying the cabinet with thin ropes of cum. He put his load inside me at the same time.
We showered together, soaping each other’s bodies, his fingers lingering on my growing breasts and the sensitive head of my cock. After we dressed and ate, I headed to work.
Lunchtime Quiz the Sequel - Thursday, March 12, Mid-day
At lunch, Linda joined Carol and me at our usual table, cheeks pink. She leaned in, voice barely above a whisper. “Last night ... were you wearing a strap-on? Because it looked real.”
I glanced at Carol, who smirked. “It is real,” I said quietly. “I’m in a drug trial. The shots are turning me into a hermaphrodite. My clit’s become a cock. It’s four and a half inches now and still growing.”
Linda’s eyes went wide. She asked, “and David. Is he ... is he ... as big as he looked?”
Carol took this one, “He’s got a big cock. Nice and fat. It really stretches a girl in all the right ways.”
Linda asked, “And he was in your butt? How does it even fit? You can’t possibly like it.”
Carol responded with a dreamy smile, “Yes. He was all the way in my ass! I love it deep and hard up there! I came so hard I saw stars.I admit it takes some preparation and practice to enjoy one that big, but it’s worth it.”
Linda twisted her napkin. “Tom ... he gave me permission. For lesbian stuff. As long as I tell him everything when I get home.”
Carol reached over and squeezed her hand. “Why don’t you come to my place after work? Just us girls first. A threesome or a hermaphrodite might be a lot for your first time stepping out.”
Linda nodded, relief and excitement mixing on her face.
On the way back to the office I called Emily. She answered on the second ring. “Be at my house tonight at six-thirty for dinner,” I told her. “Wear something sexy underneath.”
She hesitated. “I ... I have plans—”
“I’m not asking,” I said. “Six-thirty. Don’t be late.”
When I hung up, Carol and Linda were laughing. “You’re bad,” Carol said, bumping my shoulder.
I shrugged. “David pointed out last night that he still hasn’t fucked her. Time to fix that.”
Surprise Guest - Thursday, March 12, Evening
After work we hit the home gym. While we lifted, I told David, “I have a surprise for you tonight.” His eyes lit up but he didn’t press. We showered, then rushed through dinner prep, chopping vegetables and seasoning chicken while the clock ticked toward six-thirty.
The doorbell rang exactly at six-thirty-one. I opened the door and Emily stood there in a short coat, cheeks pink from the cool evening air.
“You’re a minute late,” I said, sternly. “We’ll talk about that later.”
Her eyes widened, but she stepped inside without argument. David looked up from the dining table, and I introduced them to each other. David’s eyebrows lifted in appreciation when he realized what his surprise was.
We ate the meal I’d prepared—simple grilled chicken, roasted vegetables, a bottle of red. Conversation stayed light. Emily asked about David’s work-from-home setup. David asked about her classes. I watched the way her gaze kept drifting to my chest, the way her thighs pressed together under the table. The trial’s effects still hummed through me, my nipples tight against my bra, a slow trickle of wetness already soaking my panties.
After dinner we moved to the living room. David and I took the couch. I pointed to the open space in front of us.
“Stand there, Emily.”
