Let's try a blowjob

"Right away, my master." She drops to her knees with a clank. Guess you didn't think she needed to ditch the armor first? That's cool. We all got our thing. She does remove her gauntlets though before handling your penis. Thankfully the Pharah homunculus is self-sufficient enough to do that, even when you're too busy to think of those sorts of precautions.

A strong, lender, brown hand reaches forward and brushes lightly against the tip of your cock. Her fingertips gently dance their way down the shaft and she takes your balls in them as she places her other hand upon your penis. Leaning forward, Pharah places a gentle kiss on the very tip. You feel the whole thing twitch and a glorious shiver runs down your spine. Again she kisses your cockhead, over and over, her lips following a path much like her finger tips had, only stopping when she reaches the hand she's grasping you with then moving back up.

She locks her brown eyes with yours and her tongue flits out. She licks your mushroom tip like a caricature of someone with an ice cream. And it's hard to deny it feels great. Your hand reaches down and you take hold of her black hair. She knows instinctively what to do.

Finally the head of your penis is engulfed by her lips. She forms a tight seal around it and begins to apply suction. With each little suck you feel it expand slightly then shrink back down when she ceases. She moves her head down, taking more of your length into her mouth. All the while, her tongue works its way around your encased member. She lets go of your shaft and now uses both hands to play with your balls, massaging and tugging them while she takes the entirety of your dick into her throat effortlessly.

She begins to bob her head up and down in your lap "GLUK GLUK GLUK GLUK GLUK" The sounds are immense and the pressure begins to build up in your balls.
