Her text message reply explained that she has placed a mattress on the floor in the entrance way of the incall with a sheet hung from the ceiling from wall to wall. She slides her hips onto your side of the sheet for DATY, doggie, etc and you slide your hips onto her side of the sheet for BBBJ, cowgirl, etc. You never see her face and she never sees yours. Two issues for me. First whenever I enter an incall I take 15 ish seconds to look at the surroundings and SP to get a sense of safety, security and peace of mind. Not possible with this set up as you have no idea what / who is behind the sheet (part of the intrigue but...). Second no use of bathroom to wash up before or after.
