Birthday jerk session with Heather and Tara

It is your birthday and your girl Heather has brought another girl to play, but there is a catch. You cannot touch the other girl (Tara), but you can watch them play as you jerk off. The girls are clearly pleased when they see your dick getting hard, so they kiss one another. Heather points out Tara's sexy ass, knowing that you love a gorgeous, wiggling ass. Tara then peels Heather's bra off of her, kissing and sucking along the way. Are you still stroking that dick? Though you cannot join in with the girls, you fully appreciate their beauty and encouragement to jerk your dick. The girls are both nude on the bed with you now and you can smell the sex in the air. Tara's pussy is hairy and very wet and when she puts her ass in your face, you almost blow your load. Heather rubs Tara's pussy and you think about how hard your dick is. Both of their asses are now facing you and you move a hand to your balls, per their direction.
