Gamma steps in.

Gamma takes a step closer, and Alpha suddenly draws her head back, letting your cock escape her lips. You gasp, jerking your head up, startled. Is she really going to stop now? Leaving you like this?

But as Alpha stands up and steps away, Gamma kneels down to take her place. You sigh in relief as she wraps her green lips around the head of your cock - then cry out as she takes hold of your shaft with one hand and starts to pump rapidly.

Your cock is slick from Alpha’s attentions, so Gamma’s hand glides smoothly over you in rapid, wet strokes. She holds the head of your cock trapped in her mouth, but doesn’t lower her head further, exposing the majority of your length to the strokes of her hand.

The combination hand job and blow job is incredible - the rapid pumping of her fist drives the sensation to a whole new level of intensity. You grab the arms of the chair, your hips sliding on the seat cushion, your thighs opening wide to give Gamma free access to your crotch. “Oh, god,” you moan, “oh … uhhhh … oh god ….”

A new vibration starts to run through your body, summoned forth by Gamma’s quick fingers, and you know just what’s about to happen. You start to sit up straight, your voice **** with desire. “Oh, I’m going to … oh, please, oh yes, oh please, oh, OHHH ...”

You shout, practically screaming as your cock bursts, squirting the first load of your orgasm between Gamma’s soft lips. She slows her pace a little, drawing each subsequent spurt out of you, encouraging your cock to surge and swell again and again, making you cry out every time she squeezes and tugs you. Alpha could be sharpening dental tools right now, and Beta could be charging a cattle prod, and you could care less, because at this moment, nothing in the world matters as much as having Gamma’s lips and fingers around your cock.

When your shuddering begins to subside, and your cock seems to have given its last spurt, Gamma’s hand slows to a halt. She withdraws her lips from you - very, very gently - looks up at you, and swallows, licking the cream of your orgasm from her lips with her green tongue.

You are dizzy and exhausted and amazed, and nearly ready to tell Gamma that you are desperately in love with her and you want to marry her on the spot. Or Alpha. Or Beta. Or all three of them. Do they do polygamy on Mars?

“Intriguing,” Alpha says. “I think the next experiment will be very interesting indeed.”
