Sarah makes Shasta cum on her tongue

Shasta wriggles, her long body rippling with her motion, her erect nipples bouncing a little bit on top of her small breasts. She tries to say something but it doesn't quite come out as words. From the look on Shasta's face, she's feeling really good.

You gently stroke your meat as Sarah's head bobs, and Shasta moans and writhes. Then Shasta sits up a little, looking down at Sarah's head. She holds her sister's head tightly to her pussy, saying, "Damn it, Sarah! You're gonna make me come all over your tongue!" Suddenly, her whole body arches backward and her thighs squeeze Sarah's head as Shasta explodes in a raucous orgasm. As she thrashes her head from side to side and her fists grab handfuls of sheet, her squeal fills the room, and then she screams, "Yes! Yes! My head is erupting all over the room! Fuck! Fuck! Sarah! Give me your tongue!" Shasta's climax seems like it lasts for ten minutes in your high-as-a-kite state, but eventually, she collapses to the bed in sudden loss of muscle tension. Her thighs part, and Sarah lifts her head up to suck in some much needed air. The two sisters are smiling beautifully.
