Now that Miss Radley had securely attached her harness, she motioned to her husband.
"This part may seem difficult, but you should know that a large portion of our body-weight is contained in the legs, the conjoinment conversion process makes conjoinees significantly lighter, and therefore easier for their partners to carry."
With that, Mr Radley doffed his bathrobe. There was a gasp in the room, particularly amongst the girls, as his penis was exposed to the class. Though it was soft at first, it quickly hardened, curving upwards towards his stomach. It was about 6 inches long and uncircumcised, with visible veins down the length.
Mr Radley then approached Miss Radley on the table and hoisted her up by the straps, rolling her over and pulling her towards his chest. Everyone gawked at her now-exposed crotch. They (with the exception of John) had all known this was a thing their teacher did, but they had never seen it in so much detail before. She had a definite camel-toe, but her clitoris was large enough that it poked out anyway, it was a curious sight to behold.
Miss Radley addressed the class "Its up to the couple in question whether the conjoiner or conjoinee is the one to do the insertion, Mr Radley is usually the one to do it in our case. Now if you could connect our erogenous zones"
Miss Radley almost didn't have to say it, as Mr Radley almost immediately reached down and grabbed his penis. Bending it slightly, he aligned in with Miss Radley's vulva.
"Now some of you may have issues with lubrication at first. Rest assured, with time your bodies will learn to recognize the conjoinment process and produce fluids accordingly."
John hadn't been paying that close attention, but upon closer inspection she was right, he could see fluids glistening between her legs in the fluorescent lighting of the classroom.
With that, Mr Radley began to push himself into Miss Radley's vulva, Miss Radley uttered a silent gasp as he did. The class could clearly see the tip of his cock as it spread the folds of her crotch.
Miss Radley struggled to add to her last point as her and Mr Radley's minds connected.
"For... Those of you who... are... are just starting out... bottles of lube are... available in most washrooms."
The class stared even harder as she regained her composure.
"Now I'd like to thank you for your maturity during my presentation. I'm sure you all have plenty of questions burning inside of you." Said the teacher "Before we begin the Q&A, I'd like to remind you to please use scientifically accurate terms, and to ask only legitimate questions. No jokes please."
