She sees the effect on Brynn almost immediately, as the poor girl let's out a loud moan and nearly cums on the spot, and Vena lets out a little squeak. "Gah! She squeezed tight! Gonna cum!" She grunts, before rutting Brynn's ass as hard as she can for a minute or two before burying her cock in to the hilt and cumming with a loud moan, blasting Brynn's bowels with her cum. Brynn's belly swells out, and she moans, having another orgasm as Vena empties herself. Vena pulls out, and then Brynn looks over her shoulder, with her ass gaping and pooling with cum. "P-please- m-more cock- i-in my ass!" She groans, wiggling her ass like a wanton slut.
