Time to fuck

"Alright girls, who wants it first?" You ask, indicating it's time to move on.

"I do!" Ava shouts out faster than either of the others can even open their mouths.

"Well aren't you a greedy little slut." Says the professor with a look of jealousy.

Ava just smirks back at her before standing up to get on top and ride your cock. You lean back on the chair to provide her a comfortable seat. Ava walks over the top of you and grabs the tip of your cock, lining it up with her pussy as she squats down onto your lap. She seems to already be dripping wet from the anticipation of getting your big juicy cock inside her and so she slides it in with ease. She takes a moment to slowly lower herself down, making all sorts of contorted faces as she sinks your cock deeper and deeper into her pussy.

"Oh fuuuck that feels good." Ava practically moans out as she sits down in your lap and starts grinding on your cock whilst it's buried balls deep inside her.

Meanwhile, the professor seems to have taken Emma for herself and is grinding her face into her pussy. It seems these girls had a hunger for more than just cock.

Before long Ava is bouncing on your cock happily wailing out for anyone out in the hallways to hear.

"Oh fu-uu-uuck!" She squeals out as she seems to approach orgasm from your cock penetrating deep inside her.

After reaching the end of her self-earned orgasm, she sinks down and buries you balls deep inside her whilst she huffs and puffs to recover.
