Turn up the intensity

Without saying anything, you turn your gaze to your phone. The interface is surprisingly intuitive, and you quickly see where to turn up the intensity. As you do, you can't help but let out a moan. Your cock is visibly throbbing now as pleasure ripples through it. It takes all of your willpower to keep from jerking yourself off roughly right then and there. You moan as the pleasure continues.

Sophia leans forward. "I wonder what it... feels like." She reaches a tentative hand out towards your cock, looking to you for approval. After meeting her gaze, you nod, and she slowly gets off her seat to kneel in front of you, then grasps your member. Her grip is soft, but the feeling surprises you and you utter "ung, fuck," under your breath. Sophia gasps. "I can feel it pulsing!" She looks up at you mischievously and starts to slowly stroke your shaft. You start to buck your hips. You weren't going to last long like this. Taking another look at the phone screen, you search for something to help you last longer. Finding an option to turn off your orgasm, you switch it. Your pleasure continues to build, but you get the sense that even if you tried, you couldn't cum.

You browse the other settings while your friend slowly jerks you off. You turn down the self-pleasure from the implant. Something else has caught your eye, and you have to try it.
