In your mouth

"In your mouth." you say.

"Mmmmm" she purrs "that sounds yummy. You know, I bet Marianne that your cum would be sweet." She says, mischievously winking before lifting herself off your cock, and squatting down between your legs. She gives you an ample view of her whole body, stroking your cock between her tits for a moment before greedily taking you into her mouth.

Her mouth feels almost better than her pussy, though with you this close to orgasm it's hard to be sure. She bobs her head a few times, making lurid wet noises before deepthroating almost ypur entire length. She holds that position for a moment, winking up at you, before backing off and sloppily licking your cock up and down. While doing this her hands have found your balls and are massaging them gently. She doesn't break eye contact at all through the incredible blowjob.

It only takes a few moments of her expert attention to have you right up to the edge, and Hilda sees it in your eyes. She pops your cock out of her warm mouth for just a moment. "Cum in my mouth professor. I want to taste your seed, I want to lap it all up." her words drive your over the edge, and she barely manages to seal her lips around your cock before you explode inside her, pumping out over a week of pent up semen. She coughs and sputters as you pump more and more inside of her, until she can't take it all and some pills out of her mouth and down onto her tits.

"Professor" she coughs and drools, "that was incredible" and all you can do is nod before passing out.
