April O'neil
She’s at the absolute top of my list of dream castings along with Stoya and Bobbi Starr. Her NA scene was terrific way back when she filmed it, but she deserves a scene with better tech. If there’s any way to get her…
Please, SLR, make our dreams come true.
One of my all time favorite pornstars
April is my favorite. I really wish we could see her in VR again. There are so few scenes and they look rather dated. Please make it happen!
This girl rocks pigtails better than any other IMO, has very fuckable tits, and normally comes off as pretty genuine or into it
I hope the SLR team looks into this

Her scene with Naughty America is the only reason to have a subscription to that site. I would love to see a new one.
Her scenes with Wood Rocket are some of my favorite ever. She's so sexy. We NEED those tits in vr again!

Renewing my pleas for SLR to make this happen. She'd undoubtedly deliver a stellar performance.
