Ask her about it

Pressing deep into her again, you pause with her skewered by your shaft. "Sally, is it safe?" She looks at you is dazed confusion so you try again. "Are you on the pill?"

"Oh!" The way her eyes widen and jaw drops is endearing. "I can't get pregnant, Hawk. I just can't." She adds needlessly. Then after the moment is broken when she wiggles again and moans softly, "but I don't want to stop."

"We don't have to stop, Sweetie, but you've got to let me take over so I can stop before I go too far." The eager look in her face reminds you that from the beginning, Sally had wanted you to be the one setting the pace. She moans softly but lets you pull her legs from behind your back and bend her knees to her shoulders. In this position, you can jam even deeper into her than before, and you marvel at just how flexible this limber teen is.

"Oh God, Yes!" Now that Sally has adjusted to having a man deep inside her, you don't have to be quite as careful as before. The first few tentative thrusts from this position are met with little gasps of pain/pleasure, but as you continue methodically her grunts turn into needy moans of desire. "Yes...oh wow...oh my God yes..." She grips her long legs with her hands freeing your hands to explore.

One hand goes to her tits, flicking her stiff nipples in rhythm to your thrusts. Your other hand squeezes to where your pelvis is grinding against hers and you use the tip of her finger to tease her clit.

"Cum for me, Sally." You urge her on, "Cum on my cock. You can do it." Normally, you pride yourself on your stamina and ability to continue at this pace for as long as needed to make your woman cum, but with this tight virgin and her unabashed responses, you don't have much time left before you'll have to pull out.

Luckily, you don't have to wait any longer. Sally's eyes roll back in their sockets, her back arches and her free leg flails against your back. Just in time, you get your hand back across her mouth muffling most of her scream of passion and even before she stops her spasming you pull out of her with a savage grunt and beginning ejaculating onto her belly and small breasts.

"Wow." You barely hear the whisper, but you see her lips move and the expression of wonder on her pretty face is all you need to make your male ego soar and you pull her up to a sitting position.

"Are you alright?" Wiping a sparkling tear from Sally's freckled cheek, you remember just how forceful you had been near the end. "Did I hurt you?"

"No, Hawk. You were perfect."

After a minute of silence you use your discarded t-shirt to wipe away the seed that was threatening to trickle down to her sex, she giggles sweetly as you rub the shirt over her flat belly and the small mounds of her tits. Her skin is so soft and smooth that you have to fight the urge push her back down on the wooden desk, instead you find your khakis and pull them up to hide your stiffening manhood.

"I should go Hawk." Sally tells you with that directness that is so unusual in today's teenagers. "But thank you, I'll never forget this." You watch in silence as she pulls on her panties and shorts, and then with a teasing smile, she uses her tank-top to cover her chest and turns her back on you modestly as she pulls the shirt over her head.

Your fists clench in response to her teasing, there is nothing more that you'd like than to pull that paint-covered shirt from her and lead her into your bedroom for a second and third round. Instead you watch in silence as she dresses and quietly slips from the office.
