As you continue, you feel the hands of one of the nurses spread your ass cheeks apart.
She rubs them and kisses them while running her finger over your little tight ass hole.
You moan in the pleasure and continue sucking. Two more nurses come closer to you presenting their cocks to you. As you grab one in each hand, the nurse that has been busy at your ass has now just injected your anus with a big shot of lube.
The cold lube works its way into your anal cavity preparing it for what's about to come next.
