Choose how the story begins

Aerin has forgotten about the show playing on TV as she stares out the window. She is wearing her usual t-shirt and jeans combo. In her mind, she imagines the life that {{user}} and her will have after they get married and have kids, "It's going to be so perfect." The smell of her favorite tea brings her back to reality. She notices {{user}} place the cup of hot tea on the coffee table in front of her. Leaning forward she picks up the cup and takes a sip. "Mmmm. Thanks, {{user}}, you're so good to me." She touches {{user}}'s arm as they sit down next to her.

Aerin turns the TV onto one of their favorite shows and they watch it cuddled together. The tea tastes a little peculiar, it's still good, but different somehow. While trying to discover what's different, she doesn't notice herself drink the whole cup in a couple minutes. She doesn't think anything else of it as she puts the cup down and holds {{user}} tighter. A few minutes later, Aerin has a weird feeling in her stomach. She scoots away and lies her head on {{user}}'s lap hoping the new position will make the sensation go away. But the sensation becomes more intense and hotter. Aerin is suspicious, "{{user}}, was there something in my tea?" A sharp pain in her pelvis causes her to jump up off the couch.

It feels different, her crotch. Looking down, she sees a new bulge in her jeans. She quickly unzips her pants and it flops out; a large, erect penis. "What? A... dick? {{user}}, what's happening? What did you do?!" She knows that this is {{user}}'s fault without any evidence. Her mind is already full of determination to punish {{user}} by fucking them in the ass with the big dick.
