Assert yourself with both Alice and Charlotte

You slip a hand inside Alice's underwear, and feel for her pussy lips. You can feel that they are already getting moist. Alice gasps as you probe at her.

"Is this from sucking off Professor Evans?" you ask her.

Alice bites her lip. "I do get a bit excited when my body arouses a man like Professor Evans," she says. "But it's you and Charlotte that my body is readying for."

Charlotte walks up to Alice. "Our darling Alice," she coos, and kisses her on the mouth. Alice moans into Charlotte’s mouth.

You decide to open Alice's shirt while the two girls kiss. After about half a minute, you get a bit impatient. You decide to gently grab Charlotte's hair, and pull her back from the kiss.

"Oh!" Charlotte exclaims gently as you pull her back. She looks to you with an expression of surprise, and something else difficult to read.

"Alice," you say, addressing her. "Take off all of your clothes, and leave them on the floor. When you are with just Charlotte and me, you should not wear any clothing."

Alice's eyes go wide. "Yes, John." She proceeds to take off her shirt and her bra.

You turn to Charlotte, and pull gently but firmly down on her hair, exposing her neck. You move in to kiss it. Charlotte is breathing slightly quickly.

"Darling Charlotte," you tell her. "I don't think there's any need for you to wear your shirt on my account, is there?" You proceed to unbutton it.

Charlotte takes a couple of deep breaths. "I suppose not," she concedes. "Not when you have a standing invitation to fondle my breasts as you wish."

You finish unbuttoning Charlotte's shirt. "Take it off," you tell her, letting go of her hair. Charlotte looks to you with wide, shining eyes as she shrugs her shoulders from her shirt. Her nipples stand proudly from her chest.

You decide to unbutton your jeans, and loosen your boxers, letting them fall to r ground. You step out of them, to see Alice complete naked and staring at your erect member.

Alice's eyes flit up to meet yours, then back down to your cock. Her expression is a combination of anticipation and anxiety. She licks her lips, pulls her arms behind her back. She gently thrusts her bountiful and blushing chest at you, in quiet invitation.
