Ties you up in bed

Sophia continues to play with you, gently squeezing your cock, then slowly stroking it when you hold still. She only gives it a couple of quick strokes before she releases you. Each time, you involuntarily let out a small whimper, and she giggles. She teases you in this way for a few minutes, and you feel your dick straining against the invisible bonds. You feel as though you're on the verge of exploding when she stops and sits back, watching your dick twitch on its own. You look at her pleadingly, but keep yourself from moving. You don't like the sound of "punishment".

She stands up, phone in hand, and you openly gawk at the sight of your hot friend standing over you in lingerie. You can't tell exactly which factor is pushing you to the edge, but between Sophia and the implant, your cock is harder than its ever been.

She gestures you to follow her as she walks towards what you imagine is her bedroom. You don't need much more of an invitation and you scramble to your feet, following after her. Once you get there, you see Sophia pointing at the bed. "Kneel." She commands. You hesitate, but she holds the phone up, threateningly. "Uh, okay..." you mumble, getting into bed. As you kneel on her soft sheets, cock hard at attention, she smacks your face lightly, smiling coyly. "Call me Mistress, ****." Your heart pounds. "Yes, Mistress."

She orders you to lie back in bed, spreading your arms and legs. Seemingly out of nowhere, she pulls out some wrist and ankle straps, affixes them to your limbs, and pulls them tight. Apparently she was a little kinkier than she let on. She smiles knowingly at you. Straining briefly at your bonds, you find them impossible to break out of. Turning your attention back to Sophia, you see her slowly slipping her panties down her legs, revealing her tight pussy. Your heartbeat reaches right to your cock and it twitches in anticipation.
