Finish inside her

Your sister gave you the go-ahead, so it's okay. You kiss her hard, drilling your tongue into her mouth. You keep pumping into her hot little cunt and move a hand up to her breast, squeezing it and pinching her nipple hard. Amy screams into your mouth as her orgasm blooms again. She humps up into you as you plunder her once-pure pussy. You both are completely lost in your lust.

Amy's arms wrap around your body, and her legs clasp your hips as she comes hard. You can feel her pussy muscles beating hard against your shaft.

Your mind is flooded with **** pleasure, more than you've ever experienced before. You push all the way inside her wonderfully-abused cunt and your body jerks hard as you erupt deep within Amy's willing womb. You both break the kiss and arch your backs as your orgasms merge into a mammoth explosion of bodies, sweat, lust, and fluids. Your hot seed seems to make your sister climax harder, and very unladylike animal grunts emerge from her tiny throat.

You rapidly piston in and out of her, even after you've finished coming, because her body still shakes and gyrates for many minutes. Her limbs hold you so tight, you couldn't pull out now if you tried.

Suddenly, her orgasm stops and her body collapses in a heap with you on top of her. Your cock is firmly inside her, kept hard by frequent aftershocks that squeeze you. Amy struggles to catch her breath from the pounding and ecstasy you've given her.
