Not long enough, if you ask me...

It feels all too soon that your warm moment with Erin is interrupted by the sound of a familiar throat clearing, even if it wasn't technically a sound coming from a throat anymore.

"Vell, gut job, mein sohn. If dere vas ever any doubt det you inherited mein genes, I dink det seeing det hes dispelled dem.", you hear your father say from behind you and you are suddenly reminded that he was in the room (well, his brain and eyes were) and had bore witness to you fucking the living hell out of Erin. That brought all sorts of awkwardness right back into the moment as you sigh and reluctantly pull your softening cock out of Erin.

"Really, Dad? The fact that you designed almost everything about me physically didn't dispel that fact?", you say as you reach down to pull up your pants and tuck your cock back into your boxers, "Also, do you know how creepy it is that you were here watching the whole time?"

"Vell, I could nod walk oud of here, now could I? I hed little choice in dis metter, ja?", he says and you have to admit that's technically correct.

"Yeah, well...still creepy."

"Nonsense. I em a doctor. I heff witnessed efery biological occurrence both in nature und in artificially crafted circumstances. Dere is no reason to be embarrassed.", he said and added, as though trying to make you feel better, "You acquitted yourself very vell, mein sohn. You heff a proper technique und strength und stamina to make proper use of det technique."

"...It's ten times creepier that you're giving me an 'attaboy' speech about my sexual technique, you know that, right?", you reply.

"Ach, dere is no pleasing you.", he scoffs and, deciding that there was no alleviating your embarrassment in this moment, he goes on, "Vell den, now det you heff gifen to Subject A-Vun vhat is needed, you should go on to de others und repeat de process, ja?"

"Jeez, Dad, can't a guy get a couple of minutes to enjoy the afterglow and recover?", you gripe as you move to help Erin up off the table, the gorilla-woman apparently finding it difficult to stand steady on her own feet after the fucking you gave her.

"Det vould be unnecessary, Dietrich. Your refractory period should be no more den a minute or two et de most.", your father states matter of factly.

"...I don't even want to know how you know that."

"I vould assume you already know how I vould know det, Dietrich. But if it makes you feel better to pretend you do nod, ve can do det."

"...Gee, thanks, Dad.", you retort in a deadpan way before you shrug off your father for the moment and look back to Erin with a warm smile, "So, uh, looks like Dad wants me to go and...well, you know..."

Erin smiles gently to you and leans forward to hug you and kiss your cheek softly. "He is sending you to gift my sisters with what you have given me.", she says and then pulls back slightly to look into your eyes, hers still full of warm affection and tenderness, "Go, my Master. Let my sisters feel the joy that you have given me."

You smile sheepishly at that, finding it a bit embarrassing to have such high regard being put on your sexual prowess and semen, but nod regardless. "Yeah, okay.", you say and lean forward to kiss Erin gently on the lips, "Thanks, Erin. I'll see you later."

"Do make sure you do not harm any more of mein equipment in de midst of your coupling as you did here, Dietrich!", you hear your father say as you start to walk out of the lab, "I am not readily able to clean up after myself anymore und some of dose notes vere quite important."

"Don't drop anymore of your random crap while I'm in the middle of sex. Got it.", you say as you head towards the door, "But I promise nothing."

"Dietrich!", you hear your father shout out behind you as you leave the lab, a grin on your face at giving him a little bit of distress on your way out.
