Apparently, massaging your breasts

Despite the hesitation in your voice, you don't resist as she pulls the t-shirt up and off of you. You may not know where this is going, after all, but you're pretty sure you're going to like it. "I hurt you before," Allison whispers seductively as she lowers her face to your chest, "and now I'm going to kiss it to make it better."

She presses her lips to the top of your right breast while tracing her fingers softly around the edges. Then she lifts up just a fraction before pressing her lips down again, this time a bit to one side. Slowly, she traces a complete circle of wet sloppy kisses around your areola, before she finally moves in and plants her mouth firmly on the nipple. All the while her right hand is massaging your other breast, pressing gently but firmly into the soft flesh.

As she starts to suck on the nipple between her lips, you instinctively bring your hands up to cradle her head and softly stroke her hair. The sensation is definitely erotic, but it's also strangely comforting. The warmth of her face against your chest makes you feel somehow more secure. Her hand remains on your left breast, now gently pinching and rolling the sensitive nub at its peak.

Your pussy is gushing, but this time, you aren't in a rush to take things further. You also decide not to bother pointing out to Allison that while her lips are on your right breast, it was your left breast that she was poking a minute ago. You're perfectly content in this moment, and you don't want anything to interrupt it.

Then the door opens. "Sorry, I kind of changed my mind. I don't really need anything at home, so I just shot mom and dad a text and..." Gwen's voice trails off as she takes in the scene in front of her: you on your back, nude, Allison straddled on top of you with her face and her hands glued to your chest. The chair you were sitting in lying knocked over on the floor beside you. Both of you stare back at her like the proverbial soon-to-be-roadkill deer. It occurs to you that, from Gwen's perspective, the whole scene probably looks as if Allison tackled you to the ground for a quickie as soon as she left the room.
