Emma's turn

With you feeling your cock has been successfully rejuvenated in record breaking time, you decide it's time you fucked Emma.

"Get on that table on all fours." You say to Emma.

She obediently does as instructed and jumps up onto her hands and knees on the table. You approach from behind and align your cock from her rear.

"I think it's time you tried something new." You say, pressing the tip of your cock against her asshole.

She lets out an audible gasp the moment she realises what you intend, but before she can say anything you push as hard as you can and manage to squeeze the tip of your cock into her tight little asshole. The moment you slide it in a little further it knocks the breath out of her and stops her from saying whatever she was about to say.

You take this opportunity to start sliding your cock in and out slowly, still not having even worked half of your length inside her. This is when Emma finally manages to get a word out.

"Oh... my god... that's... in my... ass!" She gets out between deep breaths as she struggles to accomodate your girth in such a tight hole.

"That's right, it's time you learnt to take a cock up your ass."

"You're stretching me out so much. And it feels so rough. It hurts. Please."

"Alright can one of you get over here and lube her up please." You say to the professor and Ava, who have been taking turns licking each others pussies behind you in the meantime.

It's the professor who steps up to help out and comes over to Emma to help the poor girl out. Whilst you continue slowly sliding in and out of her asshole, the professor leans over the top and spits on her hole to help lube it up before getting her face in real close and licking the side of your cock as it slides in and out of Emma's asshole.

"That feel better sweety?" Professor Slattery asks in a motherly tone.

"Yeah... a little." Emma squeezes out, still focusing hard on the intense stretching sensation coming from her rear end.

"Why don't you turn over and let me help distract you from the pain."

"Ok." Emma replies.

You pull your cock out of her and allow her to flip over onto her back. With her legs pulled back up to her head, she makes a grimacing face as you prepare to slide your cock back into her asshole. It goes in a little easier this time not that it's been lubed up more and Emma has started to relax a little more. Meanwhile, the professor leans over the top of Emma and starts licking her pussy for her, further helping her relax and enjoy this new experience a little more.
