Bend over for him

As you pleasure Russ with your mouth, you feel him bring his hands on your head … dangerously close to your invisible horns. Sucking cock is kinda nice, however you can’t afford Russ finding out about what you really are.
You quickly push his hands away and stand up. Then you unbutton your pants and let them drop to the ground. Good thing you kept your shirt on, this way at least Russ won’t see the daemonic mark on your belly. For some reason that’s the only thing you never managed to make invisible. Quite an inconvenience.
Then you turn around and bend your torso over the table.

Russ starts by caressing your butt. Sliding his hands along your curves. When his fingers eventually find your quim, he starts rubbing your slit. Oh, this is so much different than with that imp. This isn’t senseless lust, this is lovemaking.
When Russ spreads your lips and presses his tip against your opening, he brought a squeal out of you. You hadn’t wanted to moan, but this one caught you off guard.
Then you feel him slide you a little. Then a bit more, and a bit more. With every slow thrust he went deeper. You close your eyes and enjoy every moment of it.

When Russ is all the way inside, you squeeze your pussy, causing him to moan. As you try to feel his size inside you, there is something that worries you. He felt smaller in you quim then he felt in your mouth.
Whatever it is probably your imagination. You push back against him, meeting his thrusts, while one of your hands travels to your cock. As Russ pounds your pussy with his human cock, you masturbate your daemonic one.

You squeeze your pussy again and … yes, this time Russ is definitely not reaching places he could before.
You turn your head to look at him and can’t believe your eyes. Russ is developing breasts!
Not just that but his hair has grown a bit longer and his hips are wider.

“Russ? Are you all right?” You ask a bit concerned.

“Oh, Sabine.” Russ replies with a feminine voice. “You are so tight.”

Now you get it. This must be the effect succubus milk has on men. You keep yourself in this position and watch Russ’s feature lose their male quality’s and get replaced by female ones. The stubbles on his chin disappear. So does his mustache. His skin becomes gentle and soft. His chest develop a beautiful pair of breasts.
All the while, you feel his dick grow smaller and smaller while you masturbate yourself faster and faster.
Eventually Russ’s dick becomes so small, it slips out of your pussy. You turn around and reveal your succubus nature, showing him your horns and mighty big cock.

“Sabine. You have one too.” A nearly female Russ says.

“Indeed.” You reply. “And much bigger than yours.”

You then poke your cockhead against Russ’s pathetic little worm. She squeals as she orgasms and a pathetic little squirt of semen shoots from her tiny dick just before it takes the shape of a clitoris and disappear between her labia.
Seeing Russ fully transform into a woman pulls you over the edge as well. You aim your cock at Russ’s belly and shoot three mighty blasts all over her. The rest dribbles down your cock over your hand.
When you are done you bring your cum covered hand to Russ’s breasts and smear your sperm on her tits.

Russ, still horny from drinking your milk, puts one hand on her stomach and starts rubbing it out. Like she’s rubbing cream on her skin. The other hand she uses to lift her cum covered breast and starts licking your sperm.

“Oh Russ.” You say. “Whatever shall I do with you.”
