If her mistress so decrees.

She does. 

"Come sit in my lap, good girl."

Berenike climbs back up.

And Seshen acquaints herself very thoroughly with her slave's body - and acquaints Berenike with some of the wonderful sensations her Mistress can give her. 

(She thinks she might love this girl.)

She brings Berenike into a pleasant, floaty haze, and then sends her own lazy smile over to her fiance. "Did you like the show, sweetheart?" she asks as she pets her slave.

"Very much, lovely. The two of you seem to have some chemistry."

"Her first words to me were 'Yes, ma'am,'" she says, kissing the top of Berenike's head. "She's delightful, and loyal, and skilled, and she's going to be so useful to my ambitions..." She leans her cheek against her slave's hair, smiling. "I see how you feel about Glaphyra, now."

"You deserve one of your own."

"We should introduce them soon."

"Mmm, that sounds like fun..."

She laughs, softly. "I want to - get used to Berenike a little before going too deep into your kind of fun." Hair pet. "I'm a strange person like that, you know."

"If I didn't like a little strange, I would have settled for bending Hypatia into shape myself, flower." Eleni comes over to give Seshen a kiss on the top of the head. "You being a strange person like that is a good thing."

Heeeee.

"Hopefully the Pharoah will see things your way," she teases.

"We'll convince her. One way or another."

"She still has divine right." Amused nudge. "So no planning rebellions, sweetheart."

"Contingencies only."

Soft kiss.

Kiss.

"Berenike's going to be useful to that, too..."

"If she retained Hypatia's skills..."

"That'd make her the most useful." Hair pets. "Though even just someone with Hypatia's face, but exceptionally loyal to me, will be useful."

"We'll have to test her further, I suppose."

"With a wide and diverse array of measures."

"Do let me know what help you need with that, flower."
