ENDING FIVE: Double the Fun

Heather has been waiting for you, she picked out a low-cut halter top and mini-skirt just for you.
For a long time, the two of you make out in her room, before eventually undressing and preparing to fuck in her bed.

But then Veronica knocks on the door, and says that Heather wants to discuss something they talked about with you.

She asks you if it's okay if Veronica can join the two of you.
"Sure, why not?" You respond, drooling.
Veronica is already naked as she makes her entrance.

As your dick takes Heather's pussy from behind, Veronica positions her spread legs in front of her sister's head. Heather shoves her face right into her sister's snatch and begins eating her out as you fuck her pussy.

Just like sisters, they came at the same time. And then switched positions.
Heather enjoys the feel of another girl's tongue for a while, but decides she both misses the tease of pussy herself, and wants to suck your balls. So she crawls under Veronica in a 69 as you pump inside her pussy.

Heather and Veronica finish you off with a double blowjob, their mouths licking up and down your length and sucking your balls in tandem until you bust a nut and cover their faces in sperm. The stacked sisters lick it all off each other and kiss passionately.
It won't be the last threesome you have that month. Next time, they treat you to a slippery double titfuck, kissing as your cock pounds their pushed together pillowy cleavages.
