No Sex, stimulation till ejaculation

Jenny: “Hahaha of course we are not going to have sex. The trial needs to be standardized of course. A machine stimulates your dick in a preset frequency. Don’t worry, its pretty slow, starting with 1 stroke every 5 seconds, becoming 1 second faster every minute, 2 strokes per second is the maximum though. The whole time it measures your hardness and of course how long it takes for you to ejaculate, just as the volume and velocity of the ejaculate. I will be there with you the whole time of course, watching you, talking to you, maybe even giving you some extra visual stimulation if needed.” she says while pulling her shirt a little, revealing more of her cleavage to him. “Visual stimulation is part of the trial, but it is not specified what kind. The standard is watching some porn, but…if you’d rather look at me instead…I’d let you.”

“I…I’d rather look at you.” He says while blushing.

She smiles. “Thats what I wanted to hear! One more thing, your data is gonna be published. But I guess that would be the least of your concerns.”
