You bed Mel
From Torg Adventure
Mel's eyes decided it for you. The adoration you saw overwhelmed your senses, her look of loving devotion struck a chord inside you. You knew then that you would do this again to see that look. Your body was taut, your nipples so hard and aching, your pussy so wet. It doesn't matter that you are not really interested in girls: that look turns you on incredibly, and whatever entity you've called wants this as payment. You pick up a lot of the entity's lust.
Mel continues to undress, pulling her tee shirt over her head, releasing her naked boobs, luscious perky orbs with fat nipples on them (that's definitely the entity, but damn if they didn't look fine). She wore bikini panties, and you can see a damp spot in the front. This is definitely a powerful spell if you can make someone lust for you, even they aren't normally interested in your gender.
You close with her and pull your shirt over your head. Her hands reach up to help remove your jeans, her eyes eager to see you naked.
