Highly Effective

The cock quickly retreated after that, as it shrivelled with a string of semen hanging from it.

"Hmmm 30 seconds, not bad." You say content with your performance not expecting another monster of a cock bulging engorged waiting for you in the hole next to the one that had a cock in it a second ago.

"Awww were you stroking this listening to you friend cum?" You ask aloud not expecting a reply just watching the cock bounce there in front of leaking precum.

Grabbing its shaft roughly "Alright your going to cum in 30 seconds just like friend because you were jerking off to him naughty boy. Starting now."

Jerking him as hard as you can rubbing the previous mans cum over his cock spitting what was left in your mouth from him on the new cock in front of you.

You hadn't even gotten to 20 seconds when you could feel his cock flexing. "That's it don't fight it big boy cum for me... go on cum!" Just like magic a massive load bigger than you had ever seen was shot in your face surprising you making you gasp and giggle.

The cock hung around for a moment then retreated back in its recess. Watching the holes now anticipating another cock to emerge from them, but none did. So you walked over to the intercom pressing the talk button.

"Is that all for today? Seems a little light from what I am used to."

Silence for a moment then a crackle from the speaker above you "That was the first phase miss, second phase is being prepared as we speak. Just watch the opposite wall miss."

A new light shone on the wall as you waited patiently.
