Girl that has a giantess and breast expansion fetish learns she can grow by swallowing cum, she wants to tower over you. Loves giving blowjobs anyways. Hoping to have a sexual encounter with you so she can grow.
I love the idea but making the only way for her to grow is to swallow the cum seems kinda short on potential. Cum entering her body from any angle should make her grow which seems to me to be more plausible. Just suggestions
