Smile, nod and then resume sucking Jimbo's dick

You smile and turn back to Jimbo's now fully erect penis, taking it back in your mouth as you feel the big agent behind you tugging down your shorts. Forming a tight noose with your lips you work your way to the base of Jimbo's shaft, sucking hungrily. Behind you the agent takes hold of your hips and positions his big cock at the entrance to your pussy.

"Here it comes Miss Smith," he breathes. You smile around Jimbo's cock at the agent's politeness, then gasp and almost chomp down on the cock-meat as you are suddenly filled from behind by his large penis.

Jimbo's runs his hands through your long blonde hair, holding your head down and humping back up into your face. Jimbo had just got out of the shower when you pounced on him so for once his dick tastes clean. Behind you the big agent his holding tight to your butt and thrusting in and out in long strong stokes. The feeling of two big cocks simultaneously inside you is wonderful and you feel your orgasm approaching.

You suck harder than ever on Jimbo's dick, trying to stay true to your promise to make him cum for a week. At the same time you push your butt back against the big agents jack-hammering penis, clutching at it with your vaginal muscles.

Jimbo is the first to cum, falling back on the bench whilst still clutching your head as his dick bursts and fills your mouth. You suck and swallow hungrily, the sudden taste of his creamy sperm jetting across your tongue actually sets you off, your whole body tensing and undulating with orgasm. This in turn completes the chain reaction, your cunt tightening it's clutch on the agents thrusting cock and squeezing him into his own orgasm.

Jimbo, his eruption over, pulls his dick out of your mouth just your other end begins to get filled with the muscled agents cum.

"Oh yes!" you gasp through clenched teeth as the last throes of orgasm coincide with the last few spurts from the unknown agents cock.

That was an entertaining interlude. Time to shower up yourself and head to the next class.
