Comfort and reassure her

You pull her to your body and hold her. "Oh, Jacklyn. I'm sorry, I should have asked you about protection. I thought you were on the pill." Then you kiss her, slipping your tongue past her lips. She returns the kiss, twirling her tongue with yours. She starts breathing heavily again. You break the kiss. You'd much rather keep having sex with Jacklyn and not get her knocked up. "Don't worry, baby. We'll get you a morning-after pill tonight. We'll use condoms until you can get on the pill."

"Oh, thank you, Jack. I'd rather not finish the school year pregnant," Jacklyn says before kissing you again. Her kiss gets hotter and you start massaging her tits and caressing her hair. She stops with a gasp and climbs on top of you, straddling your waist. Her deft fingers caress your cock, bringing new life to it. "Since we're doing something about it later, I think some more fucking is in order."

You grin up at her and say, "That's the spirit! Slide me in, baby!" You lift her hips up and she points your cock at her slit. She gets you slotted in, so you drop her hips. Her cunt swallows your cock to the hilt.

"Oh, my God! Having your cock in me just makes everything better." She starts to rock, pulling your cock in and out of her tight, slippery twat. You help her, holding her hips and guiding her. "Fuck, Jack, this is so good."

In just a few minutes, this petite girl is screaming your name as she cums. You keep your cool and your jism, since you just came. Feeling her pussy squeezing you is amazing. You pull her down to suck her nipples, and she keeps coming. Her bouncing slows, so you roll her, ending up on top, still firmly inserted inside her. You pound her sex with quick hard strokes, making her orgasm all the longer and harder.

Finally, your balls contract, sending a load to spray Jacklyn's fertile womb. You both growl as you fill her with sperm, thrusting madly. You get an image of a pregnant Jacklyn fucking you, making your shaft squirt another big dollop inside her. In a quick minute, you slump on top of her, huffing and puffing, your cock slipping from her hot box.

"Oh, god, Jack! Your cum feels so good up in me. I can feel its heat in my belly," Jacklyn says while breathing heavily. She leans up and pulls you in for a deep kiss.
