Technically the main function of breasts is for feeding babies, however in the meantime, they are very sensitive and seen as a highly sexual part of the female body.
Boobs come in all shapes and sizes, some can be full and pert, others hang a bit lower – some have tiny nipples, others are much bigger – they are all different. Real breasts wobble, move, and need support – only fake breasts look perfectly round and symmetrical. Real is far more interesting and attractive.
They all, however, can feel great when stimulated in the right way. Kissing, licking, sucking or gently tugging on the nipples can feel great, but don’t neglect the rest of the boobs, the sides (especially towards the arm-pit) can be very sensitive when stroked too.
When you are making out, copping a feel can feel nice and a bit naughty, but remember they are breasts not stress balls…
