Grab their tits

You wait patiently for the girls to walk past, before turning to them.

"Hey, come here for a second," you say to them.

The two girls, quite innocently, lean down to talk to you, their massive breasts hanging at face level. You quickly slide a hand in each of their shirts, reaching down to their large, perky nipples to tweak them quickly before just giving the breasts a long, hard squeeze of their tits.

The other follows her lead, sitting on your other knee. The first's hand slides in your waistband, her small fingers wrapping around your cock as the other twin slides her hands in and begins to massage your balls. You reach out quickly and begin groping and squeezing her tits as they gently rub your dick.

They tighten like snakes, one hand crushing both your testicles in the palm of her hand and the other tightening around your dick like a vice, ending the blood flow.
