With her breasts.

While not as voluminous as they used to be, her breasts are still quite sizeable and soft for her current frame. Sticking your fingers in her mouth, you have her get them slick with her saliva before lubing your cock. It throbs in anticipation as you tell her to cup her breasts in her hands and squeeze your cock between them. "Like this?" Selas says, pressing her breasts together and lacing her fingers behind your shaft.

"Yeah... Just like that," you moan in delight as your cock is softly smothered in purple marshmallowy pillows. "Now, keeping it in your boobs, go up and down. Up and down, just like that." You moan again as she awkwardly starts to find a rhythm, resting her elbows on your knees for support. "That's good. Go a little faster. Oh, fuck, that's good!"

Selas' eyebrows are furrowed and her tongue is poking out of her mouth in intense focus as you groan and dig your fingers into the divan from the pleasure of her titfuck. But she does occasionally lose grip of your cock as it jabs her under the chin. You fix that problem by forcing her head down and telling her to open her mouth. She does so and after instructing her to press her breasts down, you start thrusting upwards, through her cleavage and into her waiting mouth. Her succubus instincts kick in and she narrows her lips, just enough to create an audible pop every time you withdraw.

When you stop to catch your breath, Selas takes over. Keeping her lips sealed tight around your glans, she does her best to lick her way to it's center while her hands knead her breasts, the way a master baker would knead their dough, massaging your cock from every direction. Your head rolls back and your grip around her head tightens as you hang on as long as possible. "Selas. Selas. Oh shit, you're gonna make me cum!"

Excited to have her "first" taste of human cum, her hands abandons her breasts and grabs onto your hips instead, pulling herself closer to you. She starts sucking forcefully and her tail wags happily from side-to-side, as precum starts to fill her cheeks. If you don't stop her, your first shot is going down her throat instead of into her womb.
