Gotta finish inside, this is educational after all.

Mr. Carter nods. “The class won’t get the full picture if you finish outside, Mr. Alvarez. Go ahead and cum inside of Emily.”

Emily would react, but her body isn’t really in her control at the moment. She’s coming down from her third orgasm, and tries to complain between gasps. “Mr…I…I can’t…you…cum…in me….please….” It’s all nonsense, and if anything it almost sounds like Emily was begging for the cum.

Mr. Carter smiles. “You heard the girl, Tony. Cum in her.”

Tony nods enthusiastically, and quickens his pace. The class crowds around, watching Emily getting pounded over and over, until, finally, Tony cums.

To call it a simple ejaculation would be underplaying what happens, as Tony blasts a tidal wave of semen inside of Emily. She can only scream as she is immediately filled up, the massive overflow of cum making her feel like an overinflated balloon. She gasps for air, until finally, Tony slides his length out. Lacking anything to hold it in, the semen gushes out of Emily, who can do nothing but moan and twitch as her ravaged pussy pours out a waterfall of semen.

Everyone cheers, clapping Tony on the back. Mr. Carter nods. “Well done, Tony. An excellent showing.”

Emily loses track of the rest of the goings-on…as she lies there twitching and gasping, before finally passing out…
