You get acquainted with her body as well

As she is busy working your stiff erection with her hands, you slide yours up her shirt. Her breasts are more than your hands can consume. They are very large and...somewhat hard. You arch an eyebrow, but she doesn't notice. She's looking down at your thick cock, protruding more than 8 inches straight out from your hips.

You had heard rumors about Klaudina. At the end of one school year she was a B cup, then she came back the next year with what looked to be double D's. You just figured it was a growth spurt that most girls went through. Curiosity was getting the best of you now.

You start to kiss her with urgency, trying to push the tempo up a bit so you can be a bit more pushy. She goes along with it, responding with equal vigor. You push her up against the wall of the bathroom stall and kiss her neck. She grips your back tightly, digging her fingers in. You pull her shirt up, and mutter a blessing that her bra unclasps in the front. You unsnap the clasp with trembling hands, your boner pressing into the soft skin of her belly. She puts her hands in her hair, striking a pornographic pose for you as her bra falls away from her tits.

At this age you're certainly not an expert on the matter. But her tits look like the ones you see in all your favorite porns. Very large, and very perky. You're excited to finally experience augmented breasts. You reach out and cup them in your hands. They feel very firm, and you're surprised at how much you like it. You spend the next minute just groping them as she purrs and vamps like a horny slut. Your dick is jerking involuntarily, making small jumps from all the excitement.

Your heart is racing, and you feel as if you'll bust if she touches you.
