Yes unfortunately

Eve gets up and takes one halting step towards Professor Miles, then another, and kneels between his legs. You can see she's repulsed by his large stomach and hairy legs. She reaches a hand out towards the Professor's cock and hesitates. Miles sighs, grabs her hand, and puts it on his dick. She gasps but lets him start guiding her hand into stroking. Once he's satisfied he pulls his hand away.

"Alright, good girl, keep on stroking. Spit on your other hand and use both," Professor Miles says and closes his eyes for a moment. Eve reluctantly does as she's told and now you are watching your girlfriend use two hands to jack off her old fat professor while nude kneeling between his legs. You're jealous that it's not you, disgusted that she's bought it, and angry that he's caused this all to happen. Even so you know you can't intervene, you have to get to the bottom of this, and interrupting now would ruin your chance.

It doesn't mean you have to like it though. You grit your teeth as she keeps going half-heartedly. Some part of you is turned on. You look down and see a tent forming in your pants. Suddenly you hear Professor Miles start speaking.

"So Eve...we can have a...ah...conversation. It kind of...oh...reinforces the non-sexu-ah-l nature of this handjob," Miles says. You understand he's trying to put Eve at ease so she feels more confident, so she feels that this sort of behavior is normal. You think the moans should undermine his message but she does seem to be getting used to it. "Why don't you....ugh...tell me about your tennis stuff?"

Eve hesitates with the strange nature of the situation. A huge part of her wants to stop but she knows the Professor needs some help. She keeps stroking his cock, moving it slightly to the side so she can look him in the eye to hold a conversation. When his eyes aren't closed in pleasure he's looking between this goddess of a student jacking off his huge cock and her tits openly exposed right behind that. She still tries to make it feel normal.

"Uhhhh...yeah...ummm. My tennis team. We meet Tuesday and Thursdays, try to fit in practice sometimes on weekends too. We don't have official matches for a couple months but we have to keep up with it," Eve starts out uncertainly but with every word seems to be more confident. Miles, still occasionally moaning, actually manages to have a conversation about it. After a couple minutes it's like she doesn't realize she's jerking her much older Professor off out in the open in his studio. The words flow from her mouth as if holding a completely normal conversation. At one point she removes her hands to emphasize some talking point.

"Ohhh Eve, back on my cock, that-a-girl. Spit again," Miles directs her.

"Oh sorry Professor!" Eve quickly moves her hands back to his cock. Then she kneels up a bit to hover over his cock and spit a bunch on the top, letting the spit work down his shaft with her hands. You watch then as leans back on her haunches and continues stroking his cock. You can't believe she's acting as if this isn't weird as fuck!
