Walking in from a long day of work, you don't expect your lover to be in a robe and teasing you. She's horny, and that's perfect for the day you had. Not only that, but she wants to tease and entertain you really well. She toys with you a bit, saying she wants to try something new. You need to trust her though, and just agree to whatever she says if you want to have a good time.

Pulling your cock out, she sucks on it a little and licks you, kissing it and encouraging you to trust her and have fun, let go. She wants to put a condom on your dick, something you guys don't do much anymore since you're exclusive. Still, you go along with it.

No complaints when she pulls you close to fuck her. It's only just as you're close to cumming that she tells you... her little surprise...
