You swing by her place.

About an hour later you knock on the front door of her place. You'd been here a few times, hanging out or studying, but you'd never gone over when she or her mom was in heat. But here you are now, knocking on the door of a girl in heat, hoping for something that may not happen.

When she opens the door you smile and step in, offering her a hug. It quickly becomes clear the hug was awkward given how she returns the hug, and you kinda regret it. "Hey Tabs," you say. "How's things?" The close hug though, you can smell her heat, the intoxicating, arousing scent of a female wanting sex, wanting a breeding. She wasn't the first girl in heat you'd been close to, you'd bedded a few girls while overseas but never a close friend like Summer..

Following her in, you sit down opposite her, taking a glass of water she offers and the two of you settle down to catch up. Aside from the lingering scent of her heat, which you manage to ignore, you manage to focus on her, and catching up. You do notice subtle differences in how she reacts, behaves around you. She could be getting aroused, most likely was, you certainly were by the growing tent in your pants.

A few hours pass, or at least it feels like a few hours, when you're telling her a story from a training exercise, and you notice a strange expression on her face. Well, maybe not strange, you've seen it before, know what it means, what will most likely happen next.
