Let a woman tell about her foorst time having anal sex with her first partner. It wasn't long after he took her virginity. It startet with him going down on her and at first almost by accident brushing with his finger against her anus. Further in the foreplay his interest for this area persisted and as the time came to get penetrated by him, she noticed that he was aiming for another hole than usual. Without much protest she reluctantly allowed him to proceed. They skipped the stretching, since she found it weird to let him probe there wit his fingers. As lube they used the mix of her moisture and his saliva which flowed down over her anus during oral sex and some additional saliva on his penis. Let her describe how the initial insertion physically felt like for her. Which bodily sensations was she experiencing during it? What did it made feel her mentally being penetrated in this hole? How all of those feelings, sensations and thoughts changed as he started the actual penetration?
