Shy but not shy
It took months of me begging but finally my wife agreed to be shared. I blindfolded her and two of my work mates took her from behind while she was riding me. This was the most intense love making we have ever had. They both finished inside her. We took images and I can see the first one had it difficult to enter her but the second one managed to push himself all the way inside her many times - despite his larger than average size.
I asked my wife to now let me be the one taking her from behind next time. But she says this will take time for her to heal as she is all stretched and quite painful there. She says maybe next month. And just once, as she does not want those two guys to take her for granted.
LOL. She doesn't want to be taken for granted, but willing to let them do her again. Maybe she is letting you know to be extra nice to her. She knows the next time will be a lot more pleasurable for her.
