It's close, but yes

It only takes two minutes and I am ready but bust my load into Avas mouth, but I don't want this to end, and so I push both of them away. Ava just grins at me knowing I was very close. I take a few deep breaths and order Luna to watch from below. I grab Ava and throw her onto her desk. Her ass grinds against my hard cock as I try to open her pants. Once I got it I just pull it down, line up my dick at her entrance and push inside her without protection. That movement sends shivers down her spine and an electric shock from my brain, down my spine and up my cock. Time to fuck Ava.

Show me what I missed out on last week.

And I show her. I fuck Ava as hard as I can on her desk. I want to create a memory for her, that everytime she sits down at her desk, she remembers me fucking her brains out right her with Luna watching from below. I feel Lunas hand on me and when I rest a few seconds to breath she sucks in my balls and plays with them.
Yep, she is broken and my loyal fucktoy now. I start to move again and her a 'plop' when my balls move out of Lunas mouth. I remember Ava telling me about how sensitive her nipples are, especially after she got them pierced, so I play with them. I turn them, pull on them and pinch them will hammering my cock deep inside her everytime.

Luna! I shout. Wanna watch me fill Avas cunt? I see her nod and pull Avas head back. You like that, don't you? You like her watching while I fuck your pussy until your last braincells gasps for air. My other hand rubs her clit. I want you to cum so hard, that it takes me with you as well. Cum for me Ava. Cum for me and make me cum as well you fucking bathroom slut.

It takes Ava over the edge. Her pussy twitches so hard around my cock, that I cum too. My hand keps rubbing her clit and the other one grabs her by the throat. I can feel that I cum a lot which is surprising, giving I used Luna so much these past few days. My dick twitches for a solid 15 seconds inside Ava. Get ready so slurp my cum out of her pussy and don't stop until she cums again. I order Luna who as soon as I take my dick out of Ava, moves her tongue to her pussy and starts to slurp up my cum.

it is the second time in a week that I fucked a coworker without protection and maybe impregnated her. I watch on as Luna makes Ava cum twice in a row. She doesn't want to stop and starts to play with Avas asshole first with her mouth, than pushing one and later two fingers in.

I let Ava ride afterwards, with my dick deep inside her ass. Luna watches on until she can suck my cum out of Avas fucked ass. Ava and I are getting tired and I take Luna home with me, after telling Ava, that she can borrow my bitch from time to time.
