Licking ice cream is just an added touch to this image of a bitch. So her verbal signs were quickly understood and she even squirted while being fucked in the ass.
Girlfriends have fun, hooked up with a guy, though maybe on the contrary he hooked them up. All three ended up having unforgettable sex.
