28M. My GF and I were discussing kinks and fantasies the other day, and she loves the idea of wanting to be able to cum in me. Both from the perspective of filling me up, and also wanting to know what it feels like to cum inside someone.
We are both bisexual, but in a heterosexual relationship. I am into anal play and want her to peg/use anal toys on me anyway, and thought the idea of her somehow cumming in my ass was super hot.
Are there any toys or techniques people know of that could help make this biologically impossible desire more achievable?
(Edited to clarify relationship type)
